Flexibility test of Active Chest Flexibility and Shoulder Reach Flexibility tests will be performed before and after the experiment to determine their improvement in the flexibility of the pectoral muscles. After measuring the flexibility, two stretching exercises of one-arm doorway stretch and office chest stretch will be performed. it will be done twice, 30 second each with 10 second rest in between. After exercise, this group had to undergo vibration exercise by using whole body vibration machine.

vibration will be given using whole body vibration machine. The subject will place both palms on top of the vibration platform with their knee supported on the ground. They need to apply as much pressure on the vibration platform by using their body weight. The whole body vibration machine will be set at the frequency of 30 Hz and the amplitude of 5 mm. They need to hold that position for 1 minute for 3 sets with 1 minute rest in between. The researcher will immediately stop this if the subjects feel dizziness and discomfort
