The hamstrings are a group of three muscles – the femoral, semitendinous, and semimembranous biceps – that span the back of the thighs, traversing the hip and knee joint. They are the primary knee flexors and help the gluteus maximus extends its upper legs. They work almost constantly, therefore, as you are training in a stair climbing cart. For example, the hamstrings of your left leg contract to help extend the hip as you are pressing down with the left foot. at the same time as the hamstrings in your right leg contract to flex the knee as you are lifting the right foot, vice versa. Working these muscles on the climber helps tone the legs.
The quadriceps is a group of four muscles – the rectus femoris, the vastus intermedius, the vastus medialis, and the vastus medialis – which encompass the front of the thighs, facing the hamstrings. Consequently, when using stair climbing cart they facilitate the range of opposite movement – extension of the knee – and the anterior rectus also helps to flex the hip joint.

Contract the quadriceps powerfully to extend the knee every time you press the foot down when you are using a stair climbing cart. The rectus femoris also works to lift the upper leg during exercise, along with the other hip flexors. Because quadriceps is used in a variety of sports and daily activities, strengthening the muscles of the climber will make your movements more efficient.
