Start by sitting on the ground with knee extended and the back straight. Place the middle of the strap around your foot and grasp the ends near your waist.
Contract by pushing your foot downward against the strap, keeping your knee straight. Maintain your hand position. Hold for 7 seconds.
Breathe out and relax as you pull the strap towards you into dorsiflexion, stretching your calf muscle.
Repeat three times.
