Arnold Schwarzenegger took to Reddit on Saturday to urge Americans to stay indoors during the COVID-19 pandemic and "focus on the things we do control," like our physical fitness. And you don't need fancy workout equipment or a streaming service to get a good workout, the former body builder said.

The 72-year-old explained that he's always found solutions to working out without a gym. Growing up in Austria, Schwarzenegger would do pull-ups from a tree branch and chop wood to build strength. Even as a fitness professional, he would run up the stairs of a hotel to exercise.
