“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.
“The majority of recreational resistance trainers underestimate the total training volume they are capable of tolerating and adapting to.”
The evidence supports a narrower claim than this one makes. Research shows that higher training volume can sometimes produce more hypertrophy and that some lifters likely could adapt to more volume than they currently use, but no reliable study shows that most recreational lifters underestimate their own volume tolerance. It also omits that effective volume varies widely and that low-to-moderate volumes often work well.
