Mostly True 7/10
“As of May 4, 2026, resistance training performed at longer muscle lengths with greater training volume is more likely to produce greater skeletal muscle hypertrophy than resistance training performed at shorter muscle lengths and/or with lower training volume.”
Current evidence supports the overall direction of this claim, but not with equal certainty for both parts. Greater training volume is a well-established driver of hypertrophy, while training at longer muscle lengths appears beneficial on average yet usually by small margins and with some conflicting review-level evidence. The volume effect is strong; the muscle-length effect is modest and still debated.

False 2/10
“Most recreational resistance-training participants underestimate the total training volume they can tolerate and adapt to.”
The evidence does not support the claim as stated. Research cited here shows that higher training volumes can sometimes produce more hypertrophy and that many recreational lifters can adapt to a range of volumes, but it does not measure whether most people underestimate their own recoverable or adaptive volume. The claim turns a physiological finding into an unsupported statement about participants' beliefs.
