Take a hot bath instead!
A new study found that taking a hot bath can actually burn as many calories as a 30-minute walk.
British researchers had participants take hour long hot baths or ride a bicycle for an hour.
While riding a bike burned more calories, taking a bath still burned around 140 calories.
The study also found other possible health benefits to taking a hot bath like lowering blood sugar peaks after eating and boosting the immune system by reducing chronic inflammation.
