The Claim

In resistance-trained men, 8 weeks of high-intensity resistance training (3–5RM at ~90% 1RM with 3-minute rest intervals) leads to greater improvements in bench press strength compared to high-volume resistance training (10–12RM at ~70% 1RM with 1-minute rest intervals), with a reported 14.8% increase in the high-intensity group versus a 6.9% increase in the high-volume group.

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.

Cause and effect
1 study reviewed
In plain English

If you're a guy who's already used to lifting weights, doing fewer reps with heavier weights and longer rests might boost your bench press more than doing lots of reps with lighter weights and short breaks — at least over 8 weeks.

See the scientific wording

In resistance-trained men, high-intensity resistance training (3–5RM at ~90% 1RM with 3-minute rest) for 8 weeks causes greater improvements in bench press strength compared to high-volume training (10–12RM at ~70% 1RM with 1-minute rest), with a 14.8% increase in the high-intensity group versus 6.9% in the high-volume group.

1 study
  1. Study: The effect of training volume and intensity on improvements in muscular strength and size in resistance-trained men

    The study looked at two types of weight training in experienced lifters and found that lifting heavier weights with more rest led to bigger gains in bench press strength, just like the claim says.
