People did more total reps with their foot pointed up, but that didn’t make their muscles grow bigger or stronger than the leg with the foot pointed down.

Myoelectric activity and improvements in strength and hypertrophy are unaffected by the ankle position during prone leg curl exercise – a within person randomized trial

Randomized Controlled Trial

Human

2023 Nov

The study found that even though one leg did more work with the foot pulled up (dorsiflexion), both legs ended up equally strong and muscular — so doing more reps didn’t help more.

After 10 weeks of leg curls, it doesn’t matter if your foot is pointed up or down—you’ll get the same muscle growth and strength gains either way.
