Here’s the cooldown routine:

Easy jog or walk — 5 to 10 minutes

Hip circles in lunge — 30 seconds each leg

Lunge and twist — 30 seconds each leg

Pigeon Pose — 30 seconds each leg

Downward Dog with alternating calf marches — 30 seconds each leg

Run through all the above stretches on one leg first, then switch sides and do them all again.
