Sweat and Punch It Out With This 15-Minute Boxing Bag Workout From FightCamp's PJ Shirdan

• Place both hands on the ground, shoulder-width apart. Fully extend your legs so your body is in one straight line from head to toe. You should be resting on the balls of your feet.
• Keep your hands directly below your shoulders, and pull your belly button into your spine to engage your core and keep your butt from dropping.
• Actively squeeze your glutes, and picture your body as a long, straight board.
• Hold this plank position for 30 seconds.

Repeat this circuit one more time through before going to your active recovery.
