The Claim
Nine weeks of whole-body resistance training performed three times per week increases maximum dynamic strength in young men, irrespective of whether exercise variation is introduced or consistency is maintained, with all participants demonstrating significant improvements in one-repetition maximum (1RM) across multiple resistance exercises.
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 lift weights all over their body 3 times a week for 9 weeks, they'll get stronger — no matter if they switch up their exercises or stick to the same ones.

Nine weeks of whole-body resistance training performed 3 times per week increases maximum dynamic strength in young men, regardless of whether exercises are varied or kept consistent, with all participants showing significant improvements in 1RM across multiple exercises.
What the research says
1 studyStudy: Does Varying Resistance Exercises for the Same Muscle Group Promote Greater Strength Gains?
The study found that young men got stronger after nine weeks of weight training, whether they did the same exercises or switched them up—just like the claim says.
