Step-ups work your thighs, glutes, and hips simultaneously. Grab a pair of dumbbells and keep your arms at your sides throughout the exercise to pump up this simple move:
- Find a step (or bench) that you can place your foot squarely on that will bring your knee up to a 90-degree angle. Hold a dumbbell in each hand at your sides.
- Step up with the right foot, then the left, so that both feet are on the bench.
- To return to the starting position, first step down with your right foot, then the left. This is one rep.
- Perform 20 reps on each side.
