Back Bonus

Step up the traditional superman (more like superwoman!) exercise with an extra resistance layer.

WHY WE LOVE IT: Gain Marvel character strength with this total-body burner that you can do anywhere. The standard move targets the posterior chain (all those back-of-bod muscles from the neck down through the traps, glutes, hamstrings, and beyond) and activates the core, says Kristina Earnest, CPT. When you add the bonus pulldown, you put a major emphasis on the tough-to-hit lat muscles, which are key for topnotch posture and low-back pain prevention. Wins all around!
