Experiment Overview

  • For the last 100 days, the speaker conducted an experiment reducing workout volume to observe the effects.

  • The goal was to transition from a high-volume training regimen (3-4 sets per exercise) to a low-volume program (1-2 sets per exercise).

Training Volume Definition

  • Volume: Total number of hard working sets for a muscle each week.

    • High Volume: Large number of sets.

    • Low Volume: Small number of sets.

    • Example:

    • Chest Training over a week example:

      • 3 sets of chest press on Monday + 3 sets of cable flies on Thursday = 6 sets total.

    • Standard scientific guideline: 10 to 20 sets per muscle group per week.

    • Low end (10 sets):

      • Chest example: 3 sets chest press + 3 sets cable flies + 4 sets push-ups.

    • High end (20 sets): More extensive split, like incorporating various exercises on multiple days.

Current Training Regimen

  • Current full week of chest training:

    • 2 sets of incline press + 2 sets pec deck on Monday.

    • 2 sets of machine chest press on Thursday.

  • Total volume now: about 6 sets per muscle per week.

  • Specific muscle volume examples:

    • Shoulders: 10 sets

    • Back: 9 sets

    • Glutes: 9 sets

    • Quads: 8 sets

  • Average: 6.5 sets per muscle group per week.

Historical Context and Scientific Findings

  • Historically, there was a strong consensus in training science highlighting high volume as optimal for muscle growth.

  • 2010 Study by James Kger:

    • Meta-analysis of 8 studies showed that 2-3 sets were 40% more effective than 1 set at promoting muscle gains.

  • 2016 Meta-analysis by Kger et al.:

    • Examined sets per muscle per week, reaffirming the dosage effect where more volume yielded greater muscle gains.

  • 2022 Study by Pelund et al.:

    • The largest meta-analysis to date featuring 35 studies confirmed the dose-response relationship between volume and hypertrophy (muscle growth).

Critiques and Limitations of Existing Research

  • Online Criticism:

    • Claims of high volume training leading to temporary muscle swelling (edema) rather than true hypertrophy.

  • Limitations of studies:

    • Generally targeted specific muscle groups rather than overall body volume.

    • Most were conducted with subjects at maintenance calorie levels.

    • Frequently short-term (6-12 weeks) focusing on acute gains.

    • The concept of diminishing returns in muscle growth where additional volume yields ever smaller increases in muscle size.

Experiential Findings

  • The speaker undertook personal experiments to evaluate muscle retention with low volume work.

  • 100-day Experiment:

    • Split: Upper, lower, rest, upper, lower, arms, rest for 14 weeks.

    • Focused on high intensity: All sets taken to failure.

  • Observations:

    • Subject did not lose strength and noticed improvements in vascularity and fullness despite a caloric deficit.

  • Reflection on prior beliefs about volume:

    • Initially felt undertrained but adjusted perception after noticing favorable results.

    • Realized reduced volume made sessions more enjoyable and maintainable.

Specific Studies Supporting Low Volume

  • Bickl et al. Study:

    • Subjects trained legs at high volume (27 sets) followed by a significantly reduced volume phase (3 sets total). Maintained size and strength.

    • Results demonstrated that training volume needed to maintain muscle is lower than that needed to build muscle.

  • Recent study by Herman et al. (September 2023)

    • Participants with just one set per exercise in a low-volume program exhibited significant gains, demonstrating low volume's effectiveness even among experienced lifters.

Final Observations from the Experiment

  • The results of the experiment showed that not only did the subject maintain muscle mass while cutting, but also made notable strength gains.

  • Results:

    • Lost 5.5 lbs fat mass, 1.8 lbs lean mass.

    • Noteworthy:

      • Lean mass includes both muscle and water weight.

    • Between day 30 to 100: Gained 0.5 lbs lean mass while continuing to lose fat mass.

    • Recorded new personal records in key lifts, bringing improvements despite reduced overall volume.

Conclusion and Recommendations

  • The experiment demonstrated that high intensity and low volume training can be effective, especially when cutting.

  • Considerations for future training approaches:

    • For bulking: Higher volume may still be beneficial for certain muscle groups.

    • For cutting, lean towards low volume but keep intensity high to ensure muscle retention.

  • Suggested training program launched: The Minmax Program, emphasizes low-volume, high-intensity routines. Designed for time-efficient workouts to help maintain muscle during fat loss.

  • 🎯 Final thoughts: Importance of enjoyment in workouts and how this can influence adherence to training regimens.
