The Claim
Over a 6-week period, neither isometric training performed at long muscle lengths nor full range of motion isotonic training results in meaningful hypertrophy of the lateral thigh region in individuals who are already resistance-trained.
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 already someone who lifts weights, doing either static holds with your muscles stretched out or full-range weight exercises won't make the outer part of your thigh noticeably bigger in just six weeks.
See the scientific wording
Neither isometric training at long muscle lengths nor full range of motion isotonic training produces meaningful hypertrophy in the lateral thigh region of resistance-trained individuals over a 6-week period.
In people who already lift weights, the muscles don't grow bigger because the training doesn't create enough force to trigger the cells that build new muscle fibers to activate and add more material.
What the research says
1 studyFor people who already lift weights, doing either static stretches with resistance or full-range leg exercises didn’t make the outer part of their thighs bigger after six weeks — so the claim is right.
