NASA astronaut Anil Menon details exercise regimen to combat muscle and bone loss on ISS
Menon stresses daily exercise on the ISS to offset microgravity‑induced muscle atrophy and bone loss.
By Felo News Desk · Published
NASA astronaut Anil Menon posted a workout video from the International Space Station, captioning it “Stay Hard!” and emphasizing the need for daily exercise in microgravity.
Menon said astronauts can lose around 3% of bone mass each month without exercise, along with 10‑15% of muscle mass and body weight, and a drop of more than 10% in VO2 max. He explained that microgravity reduces mechanical loading on the musculoskeletal system, making resistance and cardiovascular training essential.
The astronaut credited fellow crew member Navy Captain Jack Hathaway for acting as a personal trainer, likening the intensity to that of endurance athlete David Goggins.
Menon concluded that maintaining strength and endurance is critical not only for mission tasks but also for readjusting to Earth’s gravity after long‑duration flights.
