To target your lower legs, triathlon coach Scott Seamster, C.S.C.S., suggests parking your bike and doing a heel-toe walk. “It’s good for getting your calves warmed up and ankle flexibility, and it’s good for your shins as well,” says Seamster. Take a step forward, landing on the heel of your right foot. Stay on the heel and briefly lower your torso down over your right leg. Raise your torso back up and transfer the weight onto your right foot, rolling from the heel to the ball of the foot. Rise up on the ball of the foot as high as you can, then lower down and take a step forward with your left leg, landing on your heel. Continue to walk in this way for 30 seconds to 1 minute.
