Living in space presents numerous physical and psychological hurdles. Garrett describes the major effects of space travel on the human body, particularly bone density loss and muscle atrophy, which, during his 2008 mission, resulted in about a 1% loss of bone per month. Fortunately, advances in resistive exercise technology now mitigate this issue, utilizing custom high-load, low-repetition workout machines that effectively stimulate bone growth and muscle maintenance.
