Upgrade to: Seated Calf Raises
Sit on a chair or bench with toes rested on a step or ledge in front of you — heels should be on the ground and the step should be high enough for you to feel a stretch in your calf muscle. Place dumbbells or a barbell across your thighs near the knees added resistance. Hold the weights in place with your hands as you raise your heel off the ground, squeezing your calf muscles. Pause and slowly lower heels back down until you feel a stretch. Repeat 12 to 15 times.
