1 - Set up the calf raise machine so the shoulder pads or thigh pad fit comfortably and the ball of one foot is on the platform with your heel hanging off the edge.
2 - Keep your working leg mostly straight but not locked, and let the non-working leg rest off the platform or lightly behind you without assisting.
3 - Brace your core and hold the machine handles for balance.
4 - Lower your working heel slowly until you feel a stretch through the calf.
5 - Press through the ball of your foot and raise your heel as high as possible, squeezing the calf at the top.
6 - Lower under control and repeat for the desired number of repetitions before switching legs.
