Warmer weather is on its way (really!), which means it's time to shed any winter weight gain you've been hiding under thick sweaters. This killer yet quick total-body workout is perfect for taking any extra pounds off as you firm up the spots where fat likes to hang on (you know, belly, thighs, arms). Grab a set of dumbbells and a mat, and get ready for skirt and sleeveless season.
How it works: Three or four non-consecutive days a week, complete the circuit up to 3 times, depending on the amount of time and energy you have.
