Standing on inflatable balls is an expensive way to train your core. But you can get an even better (and cheaper) workout with one-legged exercises or lifts using one arm at a time. Doing conventional lifts without the stability that comes from working both limbs together taxes your core to keep you balanced. The single-leg row doubles the challenge: one arm works while you’re standing on only one leg.

How to: Single-Leg Row

  1. Stand on one leg and hold a dumbbell in the opposite hand. Bend your hips back until your torso is parallel to the floor.
  2. Row the weight to your hip while keeping your balance.

Pro Tip: Lifting on one leg improves proprioception and foot strength.
