Planet You Go, Gravity You Find

Your Mission: Perform an exercise with balls of different weights, as if you were in different gravitational conditions, to strengthen arm and torso muscles, and improve coordination.

Astronauts’ training takes into account the influence of gravity because during their mission they will be in a free-fall microgravity environment. When astronauts are back on Earth after a six-month stay on the International Space Station, they feel tired, as if everything is extremely heavy. Astronauts need to train to get acquainted again with Earth’s gravity and do that using medicine balls to strengthen their muscles.
