Use a foam roller for postrun recovery? Smart move: This simple tool acts as a deep-tissue massager, working out kinks in overused muscles. But its benefits don't end there—it can also build strength and stability. Because the foam roller has a curved, unstable surface, adding it to an exercise, like a plank, suddenly gives a standard move a challenging twist.
"Balancing on a foam roller requires your body to recruit more muscles, especially in your core, to perform the move," says Tyler G. Travis, executive director of Lake Erie College of Osteopathic Medicine Medical Fitness and Wellness Center, who created this routine.
Try to do these exercises two to three times a week (on easy-run days so you're not too wiped out) to build total-body strength that'll help improve performance and guard against injury. (See how fit you really are with these 10 DIY Fitness Tests.)
PlankWorks abdominals, glutes, back, shoulders
To do: Place your palms shoulder width apart on the foam roller. Keep your elbows slightly flexed, your back straight, and your neck neutral. Stabilize the foam roller in this position, and hold for 30 seconds. Repeat three times.
Push-up With Leg LiftWorks chest, triceps, abdominals, glutes
To do: Start in foam-roller plank. Lower your chest toward the roller, keeping your elbows in. Lift your right leg up, then lower it. Repeat the push-up, then lift the left leg. Alternate for three sets of eight to 12 reps.
