Just because you’re bored of the treadmill, doesn’t mean you should stop cardio altogether. If you take advantage of all the cardio machines at your gym, none of them will seem like drudgery. This routine mixes equipment to keep your heart pounding and your mind focused.

How it works

We’ve made a circuit of all the best cardio machines—the treadmill, elliptical, stationary bike, and rower. Spend a minute on each and gauge your intensity by how hard they feel. You’ll work as hard as you ever did on any one machine before, but you won’t notice it. This 30-minute workout will be over in no time.


Spend one minute on each piece of equipment and repeat for rounds. Gauge your intensity with the rating of perceived exertion (RPE)—a simple 1 to 10 scale where “1” is relaxed and “10” is all-out effort. Rest only as long as it takes to transition between stations. Specific RPEs have been set for you for each round, but the machines are interchangeable. So if you can’t do the exercises in the order shown, don’t worry about it. Just hit the right RPE on each machine in turn.
