Proformance Plus PPD-806 Leg Extension / Leg Curl Combo - The Proformance Plus Leg Extension/Curl by TuffStuff offers a space-saving option for training both the hamstrings and quadriceps. Why purchase both a leg extension and a leg curl when one efficient machine serves as both? For leg extensions, adjust the pop pin so your knees are bent to 90° and the foot roller rests on top of your lower shins, just above your feet. Leg curls begin with the legs straight and the foot roller resting behind your legs, just below your calves. For leg curls, you will also need to lock the thigh hold-down support into place in order to effectively isolate the hamstrings as you curl your feet back toward your buttocks. The selectorized weight stack makes weight adjustments between the two exercises quick and easy.

Most top trainers rank leg extensions and leg curls as two of the best supplementary leg training movements. An effective leg training workout might begin with a compound movement such as squats, front squats, or leg presses. The compound movement works the entire leg musculature - hamstrings, quadriceps, glutes, and the various muscles surrounding the hip joint - as a unit. After the compound movement, single joint isolation exercises are carefully chosen to bring up weak points. Many athletes and physique competitors are “quad dominant” with proportionately stronger and better developed quadriceps than hamstrings. Leg curls are one of the most effective single joint exercises to isolate the hamstrings and correct this imbalance. A significant minority, however, have the opposite problem with well developed hamstrings and lagging quadriceps. Few exercises isolate the quads for a pump and excruciating burn like leg extensions performed to near failure. Including leg extensions and leg curls in your training routine can help prevent muscle pulls on the field or court and can add that stage ready finishing touch to your leg development.® is the EXCLUSIVE GSA Dealer for Tuff Stuff Fitness Proformance Plus and PRO-XL Sports Performance exercise equipment to the military and government.
