The "Why Didn't I Think of That?" Treadmill Workout

The title refers to what your fellow gym-goers will be saying when they see you completing this unique, fun routine! Alternating side shuffles with walking intervals is a fantastic way to bust boredom and target your leg muscles from different angles. We all spend so much time moving on a forward plane that we sometimes forget to go side-to-side—like back in grade school when we would gallop! Plus, shaking up your routine may be just what you’re looking for if you’re struggling with a plateau .

This description is based on a treadmill workout, but you can also try this outdoors. (Note: Alter the speed and interval length to suit your fitness level.)

You may get a few extra looks, but it’s well worth it! What’s the strangest workout you’ve seen someone do at the gym? Have you ever stolen those ideas after the fact?
