The space station's new Advanced Resistive Exercise Device (ARED) uses vacuum pressure to give the astronauts a workout. Think of an oversize, high-tech bicycle pump. Crew members can exercise their upper and lower bodies on the versatile machine, which also includes cable-and-pulley and flywheel mechanisms to simulate free weights. Astronauts will typically exercise on ARED for two and a half hours each day, and can customize their workouts using digital displays.
