Performing the: A Step-by-Step Tutorial Shoulder Stretch With Towel Behind The Back
Reach your left hand behind your back from below and try to grab the other end of the towel, forming a kind of 'U' shape with the towel behind your back.
Once you've got a firm grip on the towel with both hands, gently pull the towel upwards with your right hand, causing your left arm to stretch upwards along your back.
Hold this stretch for about 15 to 30 seconds, breathing deeply and making sure not to strain or cause any discomfort.
After holding the stretch, release the towel slowly and switch hands, repeating the process for the other side.
