Progressive Overload

This principle involves continually increasing the demands placed on the muscles over time, either by lifting more weight, doing more repetitions, or improving form. It is essential for stimulating muscle growth and strength gains, ensuring the body constantly adapts to new challenges.

Maximum Recoverable Volume (MRV)

MRV refers to the highest amount of training volume an individual can perform and still fully recover from, allowing for continued strength gains and adaptation. Exceeding MRV can lead to overtraining, stagnation, and increased risk of injury, so it requires listening to one's body.

Loadless Training

This practice involves flexing and squeezing muscles without external resistance to improve the mind-muscle connection and neuromuscular control. It helps individuals learn to activate specific muscles more effectively, which can translate to better performance with weights.

Glute Vectors (Rule of Thirds)

This framework categorizes glute exercises by the direction of resistance (vertical, horizontal, lateral/rotary) to ensure comprehensive development. It suggests allocating approximately one-third of glute exercises to each vector to maximize recoverable volume and target different muscle subdivisions effectively.

Muscle Memory

Muscle memory describes the phenomenon where muscles that have been previously trained can regain strength and size more quickly after a period of detraining. This is thought to be partly due to the retention of myonuclei within muscle fibers, which facilitate faster regrowth.

Recomping (Body Recomposition)

Recomping is the process of simultaneously gaining muscle mass and losing body fat. It can be achieved by maintaining a slight caloric deficit or maintenance calories while consistently engaging in resistance training and consuming adequate protein, leading to significant changes in body shape without necessarily changing scale weight.

?
What is the ideal frequency for resistance training for beginners?

For beginners, training the entire body two to three times per week is generally recommended, as it provides sufficient stimulus for growth and allows for adequate recovery between sessions.

?
How many sets per exercise are recommended for muscle growth?

While many people generically do four sets, two to three working sets per exercise are often sufficient, especially when focusing on progressive overload and pushing intensity close to failure.

?
How can individuals determine their maximum recoverable volume (MRV)?

MRV is determined by listening to your body's biofeedback; if you're consistently fatigued, excessively sore, or stagnating in strength, you may be exceeding your MRV and need to adjust training variables.

?
Do women and men need to train differently for muscle growth?

While fundamental principles of muscle growth are similar, men and women often have different aesthetic goals, leading to variations in exercise selection and training splits, such as women prioritizing lower body and men prioritizing upper body.

?
Does the speed or tempo of repetitions significantly impact muscle hypertrophy?

Research suggests that tempo does not significantly affect hypertrophy, meaning both fast and slow repetitions can build muscle similarly, though controlled tempo is important for injury prevention.

?
How can individuals continue to make strength gains over many years of lifting without getting injured?

Long-term progress requires incorporating more exercise variety, cycling through different lifts, and not always trying to set all-time personal records every week to avoid plateaus and nagging injuries.

?
What are the primary functions of the glute muscles?

The glutes primarily perform hip extension (moving the leg backward), hip abduction (raising the leg to the side), and hip external rotation (rotating the thigh outward).

?
What is the most common mistake people make when performing hip thrusts?

The most common mistake is not achieving full hip extension at the top of the movement, often due to using too heavy a weight, which limits the glute squeeze and full range of motion.

?
Is it possible to grow glutes without significantly growing the legs?

Yes, it is possible by minimizing vertical movements like squats and lunges that heavily involve the quads and hamstrings, and instead focusing on glute-specific isolation exercises like hip thrusts, kickbacks, and abduction movements.

?
Can muscle be built after age 40, or during perimenopause/menopause?

Absolutely, individuals can build muscle at any age, including after 40 and during perimenopause or menopause, though the rate of muscle growth might be somewhat blunted compared to younger years.

?
Can someone gain muscle while simultaneously losing fat (recomping)?

Yes, body recomposition is possible, especially for individuals new to training or those with excess body fat, by working hard in the gym, consuming adequate protein, and maintaining a caloric deficit or maintenance.

?
Is lifting weights or Pilates more effective for building strength?

Lifting weights is generally more effective for building strength and muscle hypertrophy compared to Pilates, which focuses more on core stability and flexibility.

?
Is spot reduction of fat possible (e.g., losing belly fat by doing crunches)?

No, spot reduction is a myth; fat loss occurs systemically across the entire body through a caloric deficit, not by exercising a specific body part.

?
What is an effective but unusual training tip for general strength and hypertrophy?

Performing one set to failure for 6-10 exercises per workout, two to three times a week, can be highly time-efficient and effective for achieving significant gains, especially when rotating exercises.

1. Prioritize Resistance Training

Engage in resistance training for both immediate and long-term health benefits, as scientific evidence strongly supports its necessity.

2. Implement Progressive Overload

Continuously increase the tension placed on muscles over time by lifting more weight, performing more repetitions, or improving control, as this is the primary mechanism for muscle growth and adaptation.

3. Optimize for Maximum Recoverable Volume (MRV)

Determine and adhere to the maximum amount of training volume from which you can fully recover, ensuring optimal muscle growth without leading to overtraining or injury.

4. Prioritize Training Enjoyment

Recognize the significant psychological component of training; prioritize enjoyment and motivation to ensure long-term consistency and better results, rather than dreading workouts.

5. Set Realistic, Sustainable Training Goals

Establish training goals that are realistic and sustainable within your lifestyle, avoiding guilt over not doing ‘more’ and focusing on consistent effort over time.

6. Combine Progressive Overload & Mind-Muscle

Optimize hypertrophy by integrating external progressive overload (increasing weight/reps) with internal mind-muscle connection (focused contraction), as these elements work synergistically.

7. Master Mind-Muscle Connection (Loadless)

Practice flexing and squeezing muscles without external load to enhance the mind-muscle connection, which is crucial for effectively targeting muscles during resistance training.

8. Track Training Progress

Utilize a logbook or app to meticulously track your training progress and set clear goals, ensuring consistent gains and preventing stagnation.

9. Prioritize Strength & Form

Focus on gaining strength over time for substantial muscle change, but never at the expense of proper form or full range of motion, to prevent injury and ensure quality.

10. Adjust Training Variables for Recovery

If training a muscle frequently (e.g., three times a week), adjust variables like volume, effort, and exercise selection to ensure proper recovery and continued strength gains, especially as you age.

11. Train When Psyched & Recovered

Achieve better results by training fewer days per week (e.g., two) when you are fully recovered and excited to lift, rather than overtraining frequently and going through the motions.

12. Embrace Personalized Hard Training

Learn to enjoy training hard, understanding that ‘hard’ is subjective and varies based on individual schedules, pain thresholds, and goals, with many effective paths to progress.

13. Prioritize Lagging Muscle Groups

To improve a lagging muscle group, increase its training volume and frequency (e.g., adding a third training day), while simultaneously reducing volume for other well-developed muscle groups.

14. Maintain Strength/Size with Less Volume

Once muscle size and strength are built, they are relatively easy to maintain with significantly less training volume, allowing for prioritization of lagging body parts.

15. Vary Exercise Selection Monthly

Avoid repeating the exact same movements constantly; switch up exercises monthly or every few weeks to continually challenge muscles and prevent plateaus.

16. Efficient Training: One Set to Failure

For efficient and effective training, consider performing one set to failure for 6-10 exercises per full-body workout, two to three times a week, as this can yield significant gains in less time.

17. Train Near Failure, Not Always To Failure

You don’t need to train every set to failure; leaving a rep or two in the tank while increasing overall volume can yield similar hypertrophy and strength gains with less injury risk.

18. Maximize Effort in Final Reps

Approach each work set by making the final two to three repetitions as difficult as possible, focusing on form and muscle activation rather than just completing more reps, to maximize adaptation.

19. Use Variety to Prevent Injury

Incorporate more exercise variety to prevent nagging injuries and ensure continuous gains over the long term, rather than sticking to the exact same movements indefinitely.

20. Recognize Overtraining Signals

Be aware that certain exercises or intensities can lead to excessive soreness or injury; learn to recognize these signals and adjust training to avoid overtraining.

21. Incorporate Deloads or Layoffs

Periodically incorporate deload weeks or short layoffs (e.g., one week every 14-16 weeks) to allow for physical and psychological recovery, heal nagging injuries, and maintain motivation.

22. Substitute Painful Exercises

If a specific exercise causes pain, substitute it with a suitable alternative for a period, rather than pushing through the pain, to prevent injury and allow for recovery.

23. Flexible Rep Ranges for Growth

Utilize a flexible approach to rep ranges (6-30 reps) for muscle growth, as both low and high reps can be effective; vary rep ranges to keep training interesting and spare joints.

24. Tempo for Longevity, Not Hypertrophy

While tempo doesn’t significantly impact hypertrophy, controlling the weight throughout the movement is crucial for longevity and preventing injuries.

25. Muscle Growth Possible at Any Age

You can absolutely grow muscle at any age, even starting in your 80s or 90s; while the rate of growth may be blunted compared to youth, significant gains are still achievable.

26. Recomp (Gain Muscle, Lose Fat)

Focus on recomping (gaining muscle while losing fat) by training hard and ensuring adequate protein intake, as evidence suggests muscle can be gained in caloric maintenance or slight deficit, avoiding large bulks and cuts.

27. Maintain Healthy Body Fat for Hormones

Maintain a healthy body fat range (e.g., 10-20% for men, 15-25% for women) to optimize hormone profiles; recomp within this range, or perform mini-bulks/cuts if necessary, rather than extreme bulking or cutting.

28. No Spot Reduction for Fat Loss

Understand that spot reduction of fat is a myth; fat loss occurs systemically through caloric deficit and increased activity, though site-specific muscle growth can improve body shape.

29. Choose Lifting for Strength Training

For strength training and muscle growth, prioritize lifting weights over Pilates, as lifting provides a more direct and effective stimulus for hypertrophy.

30. Master Six Foundational Lifts

Focus on mastering and progressively overloading six foundational lifts: squats, bench press, deadlifts, military press, chin-ups, and hip thrusts, to develop all major muscle groups.

31. Minimum Resistance Training Frequency

Aim for a minimum of two full-body resistance training sessions per week to see results, especially for beginners.

32. Maximize Muscle Gains Frequency

To maximize muscle gains, aim to train each muscle group twice a week, as this frequency is generally optimal for hypertrophy.

33. Optimal Sets Per Exercise

Perform two to three working sets per exercise after a sufficient warm-up, focusing on quality over excessive volume.

34. Three Times Weekly Training Split

Consider training full body three times per week, or use a lower-upper-lower-upper-lower split, adjusting for recovery and specific goals.

35. Gauge Progress with Loads/Reps

Use loads, sets, and reps as your objective barometer for progress, ensuring increasing demands are placed on the muscles over time.

Focus on identifying and strengthening weak links in your physique, as this targeted approach can transfer to overall strength gains in other lifts.

37. Understand Glute Functions

Understand that the glutes primarily perform hip extension (moving leg backward), hip abduction (raising leg to the side), and hip external rotation (twisting leg outward).

38. Glute Training “Rule of Thirds”

For comprehensive glute development and optimal recovery, divide your glute exercises into three categories: one-third vertical (squats, deadlifts), one-third horizontal (hip thrusts, glute bridges), and one-third lateral/rotary (abduction movements).

39. Achieve Full Hip Extension (Hip Thrusts)

When performing hip thrusts, ensure you reach full hip extension at the top of the movement, avoiding excessively heavy loads that compromise range of motion.

40. Hip Hyperextension from Hips, Not Lumbar

When achieving hip hyperextension during movements like hip thrusts, ensure the movement originates from the hips, not by arching the lower (lumbar) spine, to prevent injury.

41. Reverse Lunges for Lower Glute Max

Use reverse lunges for optimal lower glute max development, but limit them to once or twice a week due to their intensity and potential for soreness.

42. Glute-Dominant Step-Ups

To make step-ups more glute-dominant, lean forward and step onto a box such that your working thigh is parallel to the ground, emphasizing the glutes over the quads.

43. Hip Thrusts for Upper Glute Max

Consider hip thrusts for upper gluteus maximus development, as EMG suggests strong activation in this area, though more research is needed to confirm direct growth.

44. Men’s Glute Growth Strategy

For men seeking glute growth, if already performing squats and deadlifts, add hip thrusts and seated hip abduction to target glutes without compromising recovery or other upper body goals.

45. Add Hip Thrusts for Glute Growth

For significant glute growth, especially if squats and deadlifts alone aren’t sufficient, incorporate hip thrusts, starting light to master the mind-muscle connection and full range of motion, then progressively increasing strength.

46. Adjust Barbell Hip Thrust Placement

Adjust barbell placement for hip thrusts based on individual hip anatomy; some can keep it over the pubic bone, while others may need to push it onto the upper thighs to avoid pain and ensure comfort.

47. Glute-Dominant 45-Degree Hypers

Perform glute-dominant 45-degree hyperextensions by rounding the upper back and flaring feet slightly, which deactivates the spinal erectors and emphasizes glute activation for hip extension.

48. Grow Glutes Without Growing Legs

To grow glutes without significantly growing legs, minimize vertical movements like squats and lunges, and instead focus on hip thrusts, kickbacks, 45-degree hyperextensions, and abduction exercises, potentially with higher volume.

49. Embrace Hip Dips (Natural Anatomy)

Understand that ‘hip dips’ are a natural anatomical feature (a hollow point between glute medius and glute maximus) that become more pronounced with leanness; they cannot be eliminated by targeted muscle growth, so embrace them as a sign of leanness and muscularity.

50. Proper Neck Training for Posture/Strength

Incorporate proper neck training (e.g., using a plate with a towel, mouth closed, nasal breathing, tongue on roof of mouth) to improve posture, strengthen the upper spine, and enhance overall aesthetic.

51. Directly Train Neck Muscles

To grow neck muscles, you must train them directly with specific neck flexion and extension exercises, as compound movements like deadlifts and shrugs primarily grow traps, not the neck.

52. Incorporate Grip Strength Training

Improve grip strength by incorporating static hangs (progressing to one-arm hangs if back is an issue), shrugs (holding the final rep for time), farmer’s walks, or holding the last rep of deadlifts for time.

53. Calf Training: Emphasize Stretch & Partials

To grow calves, focus on the stretched position by performing full-range standing calf raises, or incorporate lengthen partials and extended partials (bottom half of the movement) at the end of sets.

54. Improve Chin-ups with Bicep Work

To improve chin-up performance, include dedicated bicep training, as stronger biceps can directly contribute to better pulling strength.

55. Train Chin-ups/Pull-downs Frequently

Incorporate chin-ups or supinated pull-downs up to three times a week, as these movements allow for quicker recovery.

56. Limit Heavy Deadlifts Frequency

If deadlifting hard, limit heavy deadlifts to once a week, especially when training frequently, as they can be very taxing and hinder recovery.

57. Self-Assess Muscle Activation

Perform a self-assessment by attempting to flex and contract individual muscles without weight, identifying those you struggle to activate and prioritizing them in training.

58. Prioritize Glute Activation

Actively incorporate glute activation exercises, as glutes often don’t activate highly during everyday movements and are prone to atrophy.

59. Grow Lower Glutes & Reduce Sagging

To reduce the appearance of ‘saggy’ lower glutes, focus on gaining strength in exercises like lunges, step-ups, squats, RDLs, and hip thrusts, combined with achieving an optimal body fat percentage through diet.

60. Manage Hip Thrust Bruising/Pain

If experiencing bruising or pain from heavy barbell hip thrusts, switch to variations like single-leg hip thrusts or partner hip thrusts (with someone sitting on your lap) to allow the hips to heal while continuing to train glutes.

61. Strength Train During Pregnancy (If Experienced)

If you are an experienced lifter, continue strength training during pregnancy as it improves outcomes; however, if new to lifting, it’s generally not recommended to start during pregnancy.

62. Modify Hip Thrusts During Pregnancy

When hip thrusting during pregnancy, use a Smith machine or barbell on the upper thighs to avoid pressure on the belly, and reduce depth as needed for comfort and safety.

63. Muscle Memory for Quick Regains

Understand that strength and size lost during layoffs are quickly regained due to muscle memory, so periodic breaks do not negate long-term progress.

If you want to maximize your gains, you need to hit a muscle probably twice a week.

Bret Contreras

If your program is working, then you're getting stronger over time. You don't need four sets to do that. You need to take notes, have a logbook or an app that keeps track of your progress, and you have a goal in mind.

Bret Contreras

If you can't flex your muscles, how can you flex your muscles against resistance?

Bret Contreras

Lifting is a lifelong journey. You can always be improving your form. You can always be learning new skills.

Bret Contreras

Tempo doesn't affect hypertrophy that much. You can have like a one second repetition and an eight second repetition and it builds muscle similarly.

Bret Contreras

The psychological component is huge. And that gets ignored.

Bret Contreras

It's hard to build, it's easy to maintain.

Beginner Full Body Resistance Training Protocol

Bret Contreras
  1. Train the entire body 2-3 times per week.
  2. Perform 2-3 working sets per exercise after a sufficient warm-up.
  3. Utilize progressive overload by tracking weights and repetitions, aiming to get stronger over time.
  4. Prioritize proper form and consistency to build foundational strength and coordination.

Bret's 'LULUL' Split (Lower, Upper, Lower, Upper, Lower)

Bret Contreras
  1. Train 5 days per week (e.g., Monday through Friday).
  2. On Lower Body days, focus on squat/lunge, hinge/pull, thrust/bridge, and abduction movement patterns.
  3. On Upper Body days, focus on compound upper body press and pull movements.
  4. Adjust the balance of lower vs. upper body days based on individual goals (e.g., women often 3 lower/2 upper, men 2 lower/3 upper).

Glute Training 'Rule of Thirds' Protocol

Bret Contreras
  1. Divide glute exercises into three categories based on the vector of resistance: vertical, horizontal, and lateral/rotary.
  2. Allocate approximately one-third of your glute exercises to vertical loading (e.g., squats, deadlifts, lunges, step-ups), which are effective but harder to recover from.
  3. Allocate approximately one-third of your glute exercises to horizontal loading (e.g., hip thrusts, glute bridges, back extensions, reverse hypers), which work the squeeze position and are easier to recover from.
  4. Allocate approximately one-third of your glute exercises to lateral/rotary loading (e.g., hip abduction movements, lateral band walks), which are easiest to recover from and target glute medius/minimus.
  5. This approach helps maximize recoverable volume and ensures comprehensive glute development by hitting different movement patterns and muscle subdivisions.

Lagging Muscle Group Specialization Protocol

Bret Contreras
  1. Identify 1-2 muscle groups that are lagging in development (aesthetically, functionally, or strength-wise).
  2. For a period of 4-6 weeks, significantly increase the training volume and frequency for the lagging muscle group (e.g., train it 3 times per week).
  3. Incorporate a variety of exercises for the lagging muscle group, including different movement types, partials, and rep ranges.
  4. Reduce the training volume for other muscle groups to maintenance levels to allow for adequate recovery and focus.
  5. After the specialization period, rotate focus to other lagging groups or return to a more balanced routine, as gains are easier to maintain once built.

One Set to Failure Training Protocol

Bret Contreras
  1. Perform 2-3 full body workouts per week.
  2. For each exercise, after a sufficient warm-up, perform one hard set to failure.
  3. Include 6-10 exercises per workout to cover all major body parts.
  4. Aim to complete workouts in approximately 45 minutes, making it highly time-efficient.
  5. Shuffle lifts, exercise order, and variations periodically to prevent plateaus, maintain motivation, and avoid injury.
