The Claim
In young men, varying resistance exercises for the same muscle group over a 9-week training period results in similar improvements in maximum dynamic strength compared to performing fixed exercises, suggesting that exercise variation does not impair the development of dynamic strength.
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 young guys switch up their weightlifting exercises for the same muscles, they’ll get just as strong as if they stuck to the same routine for 9 weeks.
See the scientific wording
In young men, varying resistance exercises for the same muscle group produces similar improvements in maximum dynamic strength as maintaining fixed exercises over a 9-week training period, indicating that exercise variation does not impair dynamic strength development.
What the research says
1 studyStudy: Does Varying Resistance Exercises for the Same Muscle Group Promote Greater Strength Gains?
The study found that switching up exercises or sticking to the same ones gave young men similar gains in lifting strength after 9 weeks, which supports the idea that changing exercises doesn’t hurt strength progress.
