1. Attach a suspension trainer to a sturdy overhead object and lengthen the straps to a point at which you would to do pushups. Grasp the handles and get into pushup position with hands under your shoulders. Your entire body should be straight and your core braced.
2. Bring your arms out to your sides as if you were giving someone a bear hug. Lower your body until you feel a stretch in your chest and then bring your arms together again.
