Foam Roller Push-Up
Start in a standard push-up position with hands shoulder-width apart on the roller. Slowly lower yourself down and press back up. This move works your shoulders, arms, chest, and core like a regular push-up, but the balance makes it much harder. Variation: Do a one-legged push-up like Allison, alternating which leg is up between sets. Just be careful not to let that roller get away from you. Ouch!
