Here are my top 5 workouts for getting the heart rate up and burning calories: 1. Power walking - pretty much same as walking, but as a brisk enough pace to get your heart rate up 2. Swimming - a great all-around workout, tones your body and your heart 3 Running - the classic, throw on your shoes and go 4. Jump rope- Rocky showed us the way 5. Biking/spinning - even if you don't own a bike, most gyms now offer spin classes a few times a day, a great high energy workout.
