The Total Gym 14000 is an all-in-one piece of exercise equipment that is used for the home and rehabilitation settings to provide strengthening. I have used it in a rehabilitation setting, and can speak to it from there. The system comes with a variety of exercise already established in a handout/booklet, and is easy to follow with the pictures in it. The Total Gym will strengthen both the upper and lower body, but I found it most effective for the lower extremities and core strengthening. The machine is not easy, using your body weight at varying levels to give you resistance. I personally found the abdominal crunches and core strength difficult even at a 3-4 level setting, which is only 30-40 percent of your body weight resistance. The squats and toe raises single leg at 80 percent body weight provided a good challenge also. I personally recommend this as a great piece of rehab equipment.
