Health claim
“Training with heavy loads and low volume primarily improves strength through neural adaptations rather than muscle size.”
Claim checked — strong evidenceMedium riskexercise
Evidence Summary
Multiple well-designed studies consistently support this claim.
Research shows heavy, low‑rep training increases motor unit recruitment and rate coding, leading to strength gains with modest hypertrophy.
