While running, the body must remain balanced on one leg at a time. Balancing poses are excellent for runners, as they improve core strength by forcing you to maintain balance. Utkatasana (Chair Pose) and Virabhadrasana III (Warrior III) are useful poses for runners. Utkatasana is also known as Chair pose, which helps to strengthen the ankle, foot, leg muscles, and balance. Virabhadrasana III also improves balance, strengthens the legs and ankles. It is known as the Warrior III pose and helps to improve the flexibility of the spine.
