Memorize these five moves and you'll have a metabolism-boosting routine you can do anywhere. All you need is a sturdy waist-high surface, like a kitchen counter, a desk, or the back of a park bench. (Consult your doctor first if you are pregnant or recovering from an injury.) "You can even do these in your street clothes," says Sadie Lincoln, the founder of Barre3, who created this sequence. Repeat it three or four times throughout the day. "By bedtime you'll have burned more calories than you would have with one 30-minute trip to the gym," says Lincoln.
