Proof that opposites attract: The new Aerobarre class at Aerospace blends one-two punches with pliés for a calorie-burning workout. What our tester did: 

• Jump right in. The instructor, Aerospace co-founder Leila Fazel, demonstrates high-kicking, arm-crossing jump-roping moves that target her arms and legs.

• Take that! Jab and hook combinations really work to engage your mind and your muscles. 

• No pain, no gain. You will feel the effects of countless plié squats on day two. (Just walking down the stairs to the subway hurt!) 

Overall, this class was a knockout.
