NASA astronaut Sunita “Suni” Williams maintained an intense fitness regimen during her nine months living and working on the International Space Station (ISS). Her commitment serves as a reminder that structure and exercise are crucial, even in times of uncertainty. Williams initially had an eight-day mission planned, but a Boeing capsule malfunction that occurred in June 2024 stretched her stay. She drew upon her deep well of practice habits to steer through this untenable reality. Her routine included waking up at 5:30 a.m. GMT and dedicating two hours to exercise, highlighting the critical role of physical activity in mitigating the effects of space travel on the body.
Williams’ commitment to fitness is actually not new. She famously ran the Boston Marathon on April 16, 2007, while aboard the ISS, becoming the first person to complete a marathon in space. This dedication continued during her recent mission, where she followed a personalized recovery program that included running, cycling, and weightlifting until 7:30 a.m.
Astronauts are required to work out in microgravity at least two hours daily. This allows them to push against the harmful effects of zero gravity, which leads to the loss of bone density and muscle atrophy. Williams’ routine goes to show just how important it is to stay physically fit, even in the special environment of spaceflight.

Tuesday evening, Williams and the other fellow astronaut Butch Wilmore greeted safely after a splash down in Florida. Later that evening, they began the trip to Houston. They’ll now go through a 45-day period of re-acclimatization to the gravity of Earth.
Holding onto structure can help create a stabilizing force when the future is unknown and possibly full of adversity. Williams' commitment to her fitness regime demonstrates the power of routine in maintaining both physical and mental well-being, even in the extraordinary circumstances of space travel.
