Not Growing? You Aren't Training Enough

TL;DR

Most lifters under-train lagging muscles because low-volume minimalism feels better, but research shows 30–52 sets per week drives more growth than 5–20.

Key Points

• 1.Volume and growth are correlated up to a surprisingly high ceiling. Studies show 30, 40, and even 52 sets per muscle per week produced better hypertrophy than 5, 10, or 20 sets — overturning earlier assumptions that 20 sets was the upper limit.
• 2.Maximum Recoverable Volume (MRV) is the key limiting concept. Coined by the presenter, MRV is the point beyond which recovery fails and growth stops; staying below it while pushing strength slightly higher each session confirms you're in the growth zone.
• 3.Real-world systemic fatigue caps per-muscle volume far below lab conditions. University studies isolate one muscle group, but training the full body compounds fatigue across all muscles, making sustained 35+ sets per muscle per week impractical for most people.
• 4.The 'Club of Sevens' low-volume approach has real but limited merit. Training 5–10 sets of 5–10 reps twice a week suits beginners, strength-size combo goals, and fast-twitch dominant muscles like chest and hamstrings — but consistently fails stubborn, slow-recovering muscles like delts and calves.
• 5.Low-volume training is psychologically seductive for clear reasons. It lets you lift heavier (more fun), involves fewer reps (less pain), accumulates less fatigue, and produces faster short-term strength gains — creating the illusion of optimal progress.
• 6.Three practical methods add volume without feeling like junk sets. Increased training frequency (e.g., curls 3x vs. 2x per week adds 50% more sets), myo-rep sets (condensed rest of 5–10 seconds multiplies failure approaches within fewer sets), and agonist supersets (e.g., cable pushdowns immediately into dips) all compress volume into less time.
• 7.Apply high-volume techniques selectively to muscles that recover fastest and grow least. Muscles that are fully recovered the next day, rarely get pumped or sore, and maintain performance set-after-set (like delts) are the primary targets — keep lower volumes for muscles that already respond well to avoid excessive systemic fatigue.
