The Claim

Even doing a huge number of leg sets—over 50 a week—didn’t make anyone’s muscles shrink, which means there might be a very high limit to how much training your muscles can handle without losing size.

In plain English

Even doing a huge number of leg sets—over 50 a week—didn’t make anyone’s muscles shrink, which means there might be a very high limit to how much training your muscles can handle without losing size.

See the scientific wording

Resistance-trained males who perform 52 weekly sets of quadriceps training over 12 weeks experience no detrimental effects on muscle hypertrophy, despite the extreme volume, suggesting a possible upper threshold for volume tolerance in this population.

  1. Study: Effects of Different Weekly Set Progressions on Muscular Adaptations in Trained Males: Is There a Dose–Response Effect?

    Even when guys did a lot of leg workouts — way more than usual — their muscles didn’t get smaller or stop growing; they just stopped getting bigger, suggesting there’s a limit to how much training helps muscle growth.
