Doing strength exercises with your knee bent further back makes your muscles weaker and harder to activate for up to two days afterward—even when you’re testing them at different knee angles—compared to doing the same exercise with your knee less bent.

Joint angle-specific neuromuscular time course of recovery after isometric resistance exercise at shorter and longer muscle lengths

Randomized Controlled Trial

Human

2024 Apr 1

When people did leg exercises with their knees bent more (90°), their muscles got more tired and took longer to recover—even when they pushed with the same force as when their knees were less bent (50°). This matches exactly what the claim says.

Similar Assertions

If you do leg exercises with your knee only slightly bent, your muscles stay strong at that angle—even right after the workout—but if you do them with your knee fully bent, your muscles get weaker at that angle and also at other angles.

When you push hard with your knee bent all the way back, your thigh muscles have to work much harder internally than when your knee is only slightly bent—even if you’re pushing with the same force on the machine.

If you do hamstring holds with your knee almost fully bent, you might get stronger at that angle more than if you do the same exercise with your knee only slightly bent—even if you're pushing with the same total force.
