"Comparative Effects of PIR and Static Stretching on Hamstring Flexibility Post-Isometric Relaxation"

Participants will undergo Post-Isometric Relaxation technique targeting the hamstring muscles. The technique involves an isometric contraction of the hamstring followed by a passive stretch. Participant will be in supine position; hip at 90° flexion, Isometric contraction of hamstrings for 7 seconds, Followed by 15 seconds of passive stretch, 10 repetitions, 3 times/week for 4 weeks

Participants will perform Active Static Stretching exercises for the hamstrings, where the stretch is held actively without assistance.Seated long sitting position. Participant actively stretches hamstrings for 30 seconds. 10 repetitions, 3 times/week for 4 week
