Straight Leg Raise and Kneeling Hip Flexor Stretch
Straight leg raise helps straighten your abdominal muscles and upper thigh. Lie on your back and ensure one leg is stretched out and the other is bent at the knee with the foot flat on the floor. Lift the extended leg, keep your knee straight. Hold briefly and then return your leg to the floor. Do this 15 times. You can switch legs and repeat. Do three sets.
Kneeling hip flexor stretch works on muscles that lie across your hip and knee joints. You can kneel on one knee, with your other leg lying in front of you at a 90-degree angle. Lean forward, bending your front knee slightly until a stretch is felt from the hip to the knee on the knee-down leg. Stay in this position for 30 seconds. Change legs and repeat. Do two sets.
