The Claim
Pre-exhaustion resistance training involving one set of leg extension at 20% 1RM followed by three sets of leg press at 75% 1RM yields similar improvements in maximal leg press strength (15-16% gain) and quadriceps hypertrophy as traditional resistance training with three sets of leg press at 75% 1RM alone in untrained adult males, despite a 37-50% reduction in total training volume.
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.
A shorter, easier leg workout gives the same muscle and strength gains as a longer, harder one for beginners, even though you're doing less overall work.
See the scientific wording
Pre-exhaustion resistance training using a single set of leg extension at 20% 1RM followed by three sets of leg press at 75% 1RM produces similar gains in maximal leg press strength (15-16% improvement) and quadriceps hypertrophy compared to traditional resistance training with three sets of leg press at 75% 1RM alone in untrained adult males, despite a 37-50% lower total training volume.
What the research says
1 studyThe study shows that doing a light leg exercise first before heavier leg workouts gives similar strength and muscle growth as doing just the heavy workouts alone, even with less overall work, which matches the claim.
