Find a way to adapt common gym tools for a reduced gravity environment and design a workout routine that can minimize bone and muscular loss while being fun and easy to use during a long term mission. In doing so consider constraints regarding weight (equipment should weigh less than 500kg) and dimensions. Consider incorporating virtual reality to simulate a jog through an astronaut’s favorite Earth destinations or incorporate gaming to motivate users.
The machine I am proposing involves two vacuum cylinders both in opposite directions which help a person to have pressure on the body whether he/she is going up or down while doing any exercise. It has the vacuum cylinders chord connected to the chest belt which an astronaut wears and does the pushups. If required, then the cylinders could be detached from the belt and with the press of a switch be inverted to bring both the cylinders in one direction with which we can further do weight exercises like dumbells, forearms etc.
