Inline skating

Burns 425 calories in 30 minutes

Skating is numero uno on our list when it comes to blasting fat and calories. The big burn stems from the side-to-side movement of your thigh and butt muscles.

And your core gets involved in a big way to keep you balanced. What’s more, you get all these benefits without putting too much stress on your knees and other joints. Skate at a strong, steady pace. (Don’t forget your helmet, wrist guards, and knee and elbow pads.)

Boost the burn: Alternate one minute of hard skating with one minute of medium-paced strokes.
