Place a wooden block a foot or so in front of a box or chair. Take a band, remove the handles, and hook the ends together via clips to form a loop/circular band. Secure the middle of the band below the wooden block, sit down on the box/seat, and pull the band over the tops of your knees (clips on top) to create tension. (If you don't have a block, put your feet on the floor and run the band underneath the balls of your feet.) Perform seated calf raises in this position: Lower your heels to the floor, then extend your ankles (technically "plantarflexion") to go up on your toes as high as possible. Squeeze the contraction in the calves at the top, then slowly lower back down.Tips: Proper leg position is knees directly over the balls of your feet. Shift the block forward or back to achieve this.
