Calf raises are one of the simplest and most effective exercises to strengthen your calf muscles.

How to do it: Stand with your feet shoulder-width apart. Slowly rise up onto your toes, lifting your heels off the ground as high as possible. Hold for a second, then lower your heels back down gently.

Repetitions: Do 2 to 3 sets of 15 to 20 repetitions.

Benefits: This exercise activates the calf muscles, improving their pumping action and boosting blood flow. It can be done anywhere-while waiting in line or during breaks at work.
