If you train your calf muscles to the point of exhaustion, it doesn't matter if you use light weights for many reps or heavy weights for fewer reps—you'll get just as strong either way over eight weeks.

For beginners, lifting heavy weights a few times or lighter weights many times both make your calf muscles about 15-18% stronger after 8 weeks.

Adding a short, weighted stretch between your workout sets might give your calf muscles a small strength boost compared to just resting, without hurting your overall workout progress.

Adding a short, weighted stretch between your workout sets can actually help your calf muscles get a little stronger over two months. This extra stretching boosts your muscle power without slowing down your regular strength training progress.

Adding long static stretches to your regular weightlifting routine might help competitive bodybuilders build stronger calf muscles. Over three months, this extra stretching could boost their leg strength by about 11%, making it a useful addition to their normal workout plan.

If new guys lift weights for 15 weeks using only part of the movement—focusing on the shorter muscle position—they build more muscle size in that specific area and get stronger at certain joint angles, according to this claim.
