Sit on the floor with your left leg bent and your right calf resting on a foam roller. Conlon recommends placing the roller an inch or two above the Achilles tendon. Support yourself by placing your hands on the mat slightly behind you. Shift some of your weight from your resting left leg so you have some pressure on your right calf and roll yourself forward one or two inches so the foam roller gets closer to your knee (a). Slowly move the foam back to the starting position above the Achilles tendon (b). When you find a tight spot, “flex and extend your ankle like your pushing down on a gas pedal,” says Peters (b). Repeat on the left side.
