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.

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.

Doing resistance exercises three times a week for six weeks will build up your calf muscles, even if you only do a small number of sets each week. This shows that beginners don't need to do a huge amount of exercise to see their lower leg muscles grow.

If women who already work out do too many sets each week, they might gain less muscle and strength than if they did fewer sets.

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.

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.
