Walk this way to strengthen your thighs, hips, and glutes without lunges!
How to do it: Tie a band (or resistance loop) and place it around your legs, about mid-shin level. You should feel a little tension when standing with your feet hip-width apart. With hands on hips, abs in tight, and back tall, take a wide step to the left, then step right foot in (always keep tension on the band, feet should never be closer than hip width). That's one "step." Try taking 8 steps to the left, and then 8 to the right, repeating 3 times total.
Also try: External hip raise.
