If you stand or walk a lot every day, your calf muscles might not grow as much when you start doing leg exercises like calf raises.

If you lift weights until your muscles are completely exhausted, it doesn't really matter if you use light weights with many reps or heavy weights with few reps—your calf muscles will grow about the same amount over two months.

When you lift weights, your calf muscles get bigger by about 6% to 20%, and that’s pretty much the same amount of growth you see in other muscles like your arms or thighs.

Adding a short, weighted stretch between your workout sets can make your calf muscles grow bigger over two months. This happens because the stretch keeps the muscle working longer, which helps it build more size than just resting normally.

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.

When people lift weights until they can't do another rep, their muscles grow about the same amount whether they use heavy or light weights — and how much they grow depends more on their own body than on how heavy the weights are.
