Abstract: Tri-Power Exercising device allows a rider to simultaneously, or on demand, exercise virtually all muscle groups in his lower and upper body. The device includes a bicycle frame, pedals, forearm bars, sliding seat, computer and electronic display recommending energy modulation amounts from various muscle groups to optimize physical performance on any given trek.
