Every week, a new STACK Challenge gives you an opportunity to test your athletic ability and win a STACK T-shirt. Take the challenge and enter to win a T-shirt by tweeting your results with #STACKChallenge.
How long can you hold a basic Plank? Test the limits of your core and shoulder strength for your chance to win a STACK T-shirt.
Perform a Plank by holding your body in the Push-Up position with your hands and feet touching the ground and your body completely straight. You can rest on either your hands or your forearms, but make sure your hips never dip.
Hold a Plank for as long as you can while maintaining good form.
