Doing more sets of calf exercises each week generally builds bigger calf muscles, but after a certain point, adding even more sets gives you less and less extra muscle growth.

If you're a young woman who hasn't trained before, doing 9 sets of calf exercises per week builds just as much muscle as doing 6 or 12 sets over six weeks. This means you can save time on your workouts without getting less growth.

Doing more calf exercises per week (going from 6 to 12 sets) doesn't actually make your calf muscles grow bigger. In a short 6-week program, women who did fewer sets saw the same muscle growth as those who did more, meaning calves might not need as much training to grow.

For women who are new to weightlifting, doing 9 sets of calf exercises a week doesn't build bigger calves any better than doing 6 or 12 sets. This suggests that when you're just starting out, your calves don't keep growing bigger just because you do more sets.

If you work out more often, your muscles grow bigger — but only if you keep increasing your workouts, because your body gets used to the same routine and stops responding as well.

Lifting weights more each week helps your muscles grow, but after about 10 sets per muscle group, doing even more doesn't help much — the extra effort gives you way less bang for your buck.
