their body weight in space, they need to use innovative techniques to create weight bearing exercise to help maintain their muscle and bone mass.


• For cardio, the astronauts use a stationary


bike adapted for space. It has no seat, and their feet are clipped to the pedals so they don’t float away.


• Running on a treadmill requires a


bungee-cord-and-harness contraption that pulls them down onto the treadmill and applies a load of 60 percent of their body weight (which is gradually increased to 85 to 100 percent over a six-month mission).


• Resistance training is performed on an


Advanced Resistive Exercise Device (ARED), an ingenious machine that mimics weight lifting by using vacuum cylinders that can apply a load of up to 600 pounds to a bar or cable allowing the astronauts to do exercises like calf raises and squats.
