The Claim
In untrained young men performing bench press training over 10 weeks with equated volume, resistance training with 12RM protocols produces significantly lower strength gains (18.7% 1RM increase) compared to 4RM (28.4%) and 8RM (29.5%) protocols, indicating that loads below approximately 80% 1RM are less effective for maximal strength development.
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.
When beginners lift weights for 10 weeks, doing fewer reps with heavier weights (like 4 or 8 reps max) builds more strength than doing more reps with lighter weights (12 reps max), even if the total work is the same.

Resistance training with 12RM protocols produces significantly lower strength gains (18.7% 1RM increase) compared to 4RM (28.4%) and 8RM (29.5%) protocols in untrained young men over 10 weeks of bench press training when volume is equated, indicating that loads below approximately 80% 1RM are less effective for maximal strength development.
What the research says
1 studyThe study tested bench press training with different weights and found that lifting lighter weights for more reps (12RM) gave less strength gain than lifting heavier weights (4RM or 8RM) when the total work was the same, just like the claim said.
