Do static leg holds build thighs like squats?
The Effects of Long Muscle Length Isometric versus Full Range of Motion Isotonic Training on Regional Quadriceps Femoris Hypertrophy in Resistance-Trained Individuals.

Surprising Findings
Isometric training at long muscle lengths may have a directional advantage in the proximal anterior thigh, despite no overall difference in quadriceps growth.
Most people assume full range of motion movements like squats stimulate more muscle growth across all regions — but this suggests holding a stretched position might uniquely target the upper thigh, even in trained individuals.
Practical Takeaways
If you want to target the upper part of your quads, try adding 2–3 sets of long-length isometric holds (knee fully extended) to your leg routine twice a week.

If you train your quads using either holding a static position with your legs stretched out or doing full squat-like movements, both ways build your thigh muscles about the same amount — neither one is better than the other.
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.
Doing static leg exercises with your thigh muscles fully stretched might grow the upper part of your thigh more than doing regular leg exercises that move through a full range, but both types of exercise end up making your whole quadriceps muscle about the same size.
If you lift weights the same amount and with the same effort, holding your muscles still (isometric) builds muscle just as well as moving them up and down (dynamic).
