Stand tall with dumbbells in both hands at your sides. Step sideways into a right lunge bending the knee to 90 degrees. Push off of the right leg to balance on the left leg and raise your arms up to shoulder height with your left arm in front and your right arm to the side. Do a few reps, then switch sides.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
