This is the Total Gym Apex G3 that has been modified for more versatility. I put the stepper under the foot to bring up the height to make it easier getting on and off to make exercises easier for older and physically challenged people. I added chains, swivels and steel handles to the cables to be able to sit further down on the sliding board to get a deeper pull in the exercises. Also has a bar for adding weight (40lbs) that can be convert to two 20lb dumbbells bars included. Excellent for doing pull ups, shoulder and chest presses, skull crushers (triceps), curls (biceps), forearms, rows, squats and calf raises, sit ups, crunches and a recumbent bike simulator! You can work every part of your body with this set up. This is truly the Total Gym, (Just ask Chuck Norris!) Includes books, operation manual, on exercises and nutrition and a DVD. Everything you need to get going on a strong and healthy life! Text Reed 801-347-7466
