The incline plane, body weight resistance, on the free-rolling glideboard, on the Total Gym 14000 challenges the proprioceptors and stabilizing muscles and incorporates multi-plane movement and unrestricted range of motion in nearly every exercise. The Total Gym 14000 uses a percentage of your body weight against gravity as its source of resistance to provide fast, safe, effective results, regardless of your individual body composition. It is fast because you are using a lot of muscles together, at the same time. This works in two ways. The Total Gym 14000 has over 200 strength, stretching and Pilates exercises, and six resistance levels, Total Gym 14000 provides full-body functional training that utilizes the core muscles of the abdomen and back in every workout.
