Its a seated quadricep extension machine and a seated hamstring curling machine both of which are extremely effective in defining, strengthening and adding size to the anterior and posterior sides of the upper leg. This space saving leg extension / leg curl combination is built to last in commercial environments. Its construction starts with heavy-duty 2 x 2 x 11 gauge American made steel tubing. This heavy frame easily supports any size user and houses the 200 lb. weight stack within the full shroud.
