For Calves That Are Strong, Defined, and Hard as a Rock, Do These 6 Muscle-Building Moves

If you're a beginner, start with step-ups instead.

• Stand with your feet slightly wider than your hips in front of a sturdy, short box (about 12 inches high or lower).
• Bend your knees, swing your arms back, and jump to the top of the box with both feet, swinging your arms forward to give you momentum.
• Stand, then jump lightly back to the floor or step back down.
