How to Tone Your Butt and Thighs Even More on Your Runs

Most people run the exact same way every time, in a forward motion, moving 18 or so inches with each step, which means working the same muscles in the same way every time you run. Challenge your muscles in new ways by varying your steps. Run with high knees, big leaps, tiny baby steps, in a zigzag, with your right or left side facing forward, or backwards (while periodically looking over your shoulder, of course). You might feel a little silly, but you'll certainly feel the lower-body burn.
