This exercise is perfect for golf, since it activates the obliques, strengthens core muscles and help to make a better turn and weight shift.
Start in the basic plank position and then twist your body and raise one arm up into side plank so that your body forms a letter “T”.
Extend your top arm up as far as you can and keep hips lifted so that your head, spineand legs form a straight line.
Hold this position for 20 to 30 seconds.
Repeat on opposite side.
Repeat motion for 8 to 10 repetitions.
This exercise will strengthen the core but also the muscles in the shoulders. Pivoting the body around the shoulder strengthens and stretches those muscles so that you gain more control of the club for more clubhead speed.
