If you keep doing partial calf raises after you can't do full ones anymore, you might boost muscle growth in your calf because you're doing way more work—about 87% more—than stopping completely.

If untrained guys keep doing partial calf raises after they can't do full ones anymore, their calf muscles get slightly thicker — about 0.6 mm more on average — compared to stopping completely.

If you keep doing partial calf raises after you can't do any more full ones, you might grow your calf muscles more.

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 you're into lifting and want bigger calves, doing either full reps or starting with partial reps (and finishing with extra partials after failure) twice a week for eight weeks can give you noticeably bigger calf muscles.

If you're someone who lifts weights and does calf raises, doing partial reps that stretch the muscle might make your calf grow just a bit more than doing full reps and then finishing with partials after you're too tired to do full ones.
