Plank with shoulder tap

Start in high plank position with yourarms straight, hands flat on the ground under your shoulders and feet in-line with your hips.

Flatten your back to keep your body in a straight line from your head to your heels.

Carefully lift one arm and tap the opposite shoulder, without rotating or twisting your hips. Keep your back flat with a tight core keeping your body as still as possible.

Alternate arms and repeat. The number of repetitions will vary depending on your current strength.
