The Claim
Twelve weeks of resistance training, consisting of 3 sessions per week with 8 exercises per session and 3 sets performed at 10-repetition maximum loads, results in a 25% increase in upper body strength, as measured by 1-repetition maximum preacher curl, among college-aged men who have prior recreational resistance training experience.
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 college guys who've lifted weights before do a specific 12-week workout plan—3 times a week, 8 exercises, 3 sets each—they'll get 25% stronger in their arms, based on how much they can lift in one go on a curl machine.

Twelve weeks of resistance training consisting of 3 sessions per week, 8 exercises per session, and 3 sets of 10-repetition maximum loads leads to a 25% increase in upper body strength, as measured by 1-repetition maximum preacher curl, in college-aged men with prior recreational resistance training experience.
What the research says
1 studyThe study looked at the exact same workout plan described in the claim and found that it really did lead to a 25% increase in arm strength for young men who had some prior lifting experience.
