If you find yourself always coming up with excuses to blow off your workout, it might be time to call in reinforcements. Asking someone close to you—such as your spouse or a friend—to break a sweat with you will not only make fitness happen (you’re not going to leave them hanging, right?), it also makes it a lot more entertaining. Recruit a buddy and try this 20-minute total-body partner workout from Pete Egoscue, an alignment and movement expert.

Start seated on opposite chairs, facing each other while holding a beach volleyball (or other similar sized ball or thick pillow) between your thighs. See who breaks into a smile first while doing a series of muscle-toning arm circles for a couple of minutes. Keep that straight face, or not (laughter burns calories too!), while performing elbow curls and sit-to-stand squats. From there, move to the ground for a series of push-and-pull movements including bicycle kicks and sit-ups. Keep your core tight as you perform flutter kicks and walkout roller coasters. Follow up with jumping jacks for an active recovery before moving into your final partner sequences: air benches, mountain climbers, and jump rope. Cool down and then give each other a high-five for a job well done!
