1 How much aerobic exercise should you get per week?

A) 30 minutes B) 150 minutes C) 5 hours

ANSWER: B) 150 minutes. The U.S. Department of Health and Human Services advises at least that much moderate-intensity aerobic activity each week. Research shows just 13 percent of men and 8 percent of women with arthritis meet that. But a recent study suggests that as little as 45 minutes may help people who have arthritis in their knees, hips, ankles or feet.

2 Lifting weights helps support joints.

True or false?

ANSWER: True. “Having strong muscles can take pressure off of the joint, which may help lessen arthritis pain,” says rheumatologist Rochelle Rosian, MD, at Cleveland Clinic.

3 It’s OK to feel some pain while working out.

True or false?
