Talk to your doctor about any specific muscle aches, mobility restrictions, and joint concerns you may have. Once you get the go-ahead to exercise, work the following stretches, courtesy of Wilson, into your daily routine. Try to perform three to four of the stretches each day, prioritizing ones that address joints or muscle groups that feel particularly tight or achy. Doing them first thing in the morning can maximize mobility for the day, says Alexander Geevarghese, D.O., a rheumatologist at Northwestern Medicine Central DuPage Hospital in Winfield, IL. And remember: Be gentle. Never push to the point of pain.
