You will step up to a platform and step back down. Stand with legs shoulder width apart and dumbbells grasped to sides facing the side of a bench.
Place foot of first leg on bench. Stand on bench by extending the hip and knee of the first leg and place the foot of the second leg on the bench. Step down with second leg by flexing the hip and the knee of the first leg. Return to original standing position by placing foot of first leg to floor. Do four sets of ten repetitions for each leg stepping up first.
Stepping a distance from the platform emphasizes the gluteus maximus, and stepping close to the bench emphasizes the quadriceps.
