Belts may move in only one direction, but that doesn't mean you can't move in others. Walking sideways works your inner and outer thighs in addition to the entire glute group, increases exercise efficiency, and strengthens and stretches hips, says certified personal trainer Jeff Rogers, owner of Rogcity Fitness. He recommends running or walking for 5 minutes and then side shuffling for 60 seconds on each side. Repeat the full 7-minute set about three times (be sure to warm up and cool down before and after).
If you’ve never done a side shuffle before, Rogers suggests starting slowly at about 2 miles per hour with no incline and holding on to the handlebars. Gradually increase your speed and let go of the bars when it feels comfortable. To get the most out of turning to your side, engage your core, bend your knees slightly behind your toes, keep your back straight, and look forward.
