Firstly, she uses an Advanced Resistive Exercise Device (ARED), a “one-stop weightlifting machine.”
It looks like a regular hydraulic machine but instead of using weights and gravity for resistance, it uses a pair of vacuum tubes. Fortunately, you can do nearly any exercise on it – from squats to lifts to presses.
For cardio, instead of heading outside and smelling the fresh air, they use a treadmill-like instrument, named the T2 (Treadmill 2). While they run, they attach themselves with bungee cords and a harness to stop them from floating away in microgravity.
“It’s pretty fun to run on T2. You get a little extra spring in your step," Meir adds.
Lastly, they also have the option of the closest thing they can use to a bike – the Cycle Ergometer with Vibration Isolation and Stabilisation (CEVIS).
Just like a bike, you can pedal away. But instead of a seat or handlebar, you use a pair of handholds to stay in position.
Meir's peer Drew Morgan says it does a much better job of staying fit, “I get a much greater heart rate doing this than I do running on the treadmill.”
Next time you do a balcony workout or a backyard circuit, appreciate the view you have because others are far more crammed.
