The Claim
In resistance-trained men undergoing 8 weeks of high-frequency resistance training (4 sessions per week), intrinsic motivation increases significantly (effect size = 1.28) when exercises and repetition ranges are randomized session-to-session, while intrinsic motivation shows non-significant declines (effect size = -0.75) in those following a fixed routine.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If gym guys switch up their workouts randomly every time, they stay more motivated over 8 weeks compared to doing the same routine every time.
See the scientific wording
In resistance-trained men undergoing 8 weeks of high-frequency resistance training (4 sessions/week), intrinsic motivation increases significantly (ES = 1.28) when exercises and repetition ranges are randomized session-to-session, whereas motivation shows non-significant declines in those following a fixed routine (ES = -0.75).
What the research says
1 studyThe study found that when people switched up their workouts randomly, they felt more motivated to keep going, while those who did the same routine didn’t feel much change in motivation—just like the claim says.
