The MG-6727 Seated Leg Extension with Weight Plates from GANAS Fitness is a high-quality strength equipment specifically designed to isolate the quadriceps muscles at the front of the leg. Leg extensions are a great finishing exercise after prime movers like squats, hack squats, or leg presses, and can really help bring out that teardrop shape that your lower quads right above your knees are going for. If done slowly and with strict form, including full contraction at the top and extension at the bottom, the GANAS Select Leg Extension can be a valuable ingredient in increasing quadriceps strength and mass.
