The space exploration program has hired you for advice on how to keep astronauts healthy in the space shuttle. How can the program’s doctors make sure the astronauts’ bodies work well enough to exercise in space?

These programs ensure that astronauts can do exercise by using Resistance Exercise Devices

Explanation:

Astronauts float around in space due to microgravity, which is an environment that doesn't have the resistance needed to do exercise. Effective health programs must be specifically developed to minimize muscle atrophy, which is accomplished through intensive exercises together with a healthy diet. Astronauts can spend more than 2 hours per day exercising. For such purpose, astronauts use Resistance Exercise Devices positioned on a support platform in order to offset muscle loss by strength training and by making cardiovascular workouts.
