Fig. 5From: Effect of free-weight vs. machine-based strength training on maximal strength, hypertrophy and jump performance – a systematic review and meta-analysisShows the effect sizes (mean ± SD) of changes from pre-test to post-test in maximal strength (A), hypertrophy (B), vertical jump height (C) and isometric strength (D). Black are changes in free-weight when participants trained with free-weights and grey are changes in machine groups when participants trained with machinesBack to article page
