Doing calf raises with a shorter range of motion while your foot is pulled up might make your calf muscle work harder in that position, which could help you build more muscle in fewer sets.

If untrained guys do calf raises with their toes pointed up, they might build more muscle per rep because the muscle is stretched and working harder at that angle.

Doing calf raises at the bottom part of the movement — where your calf is stretched — might build more calf muscle in young women than doing the full raise, according to this claim.

Doing calf raises through a shorter range of motion, when the muscle is more stretched, might build more calf muscle in young women compared to doing full up-and-down reps — especially in the inner part of the calf.

If you're a guy new to calf workouts, doing extra partial reps after hitting failure on full calf raises doesn’t give you more muscle growth — it’s just as good as sticking to full reps, and both methods boost calf size by about 8% in 10 weeks.

If untrained guys do calf raises that only go partway up after hitting failure on full calf raises, they can do about 64% more reps without increasing overall workload—because the shorter movement is easier on the muscles.
