The Claim
In individuals performing resistance exercises using machines through a full range of motion, emphasizing either the lengthened or shortened phase of the movement does not result in significant differences in muscle hypertrophy or strength gains.
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 you're lifting weights on machines and going through the full motion, it doesn't really matter whether you focus more on the stretch or squeeze part — you'll gain about the same muscle and strength.
See the scientific wording
When performing resistance exercises through a full range of motion using machines, biasing tension toward the lengthened or shortened phase of the movement does not significantly affect muscle hypertrophy or strength gains.
What the research says
1 studyThe study found that doing exercises with a full range of motion or focusing only on the stretched part of the movement led to similar muscle growth and strength gains. This supports the idea that it doesn’t matter much where you focus the effort during the exercise.
