If your gym offers a tire Opens a New Window.and sledgehammerOpens a New Window., then you probably (read: definitely) want to get to swinging and flippingOpens a New Window.. That’s because whaling on and flipping a tire recruits all your upper-body Opens a New Window.and core muscles and builds lower-body power, while also jacking up your heart rate.

The best part: Letting the hammer rip (albeit, safely) is a great way to relieve stress. (It’s a hell of a lot more fun than jogging on a treadmill, too.)
