Catching up with your BFF is fun. Pushing each other to the next level? Even better! 

That’s the beauty of our partner workout: You’ll not only spend time together, but you’ll also exercise way harder than if you were going through the motions solo. “You push yourself more than you would on your own. You can’t flake,” notes Barry Jay, a cofounder of Barry’s Bootcamp, home to one of the most body-morphing workouts around, and a big fan of partner workouts.

But don’t expect to be dishing about last night’s date: Jay and fellow Barry’s Bootcamp trainer Astrid McGuire created a fun but fierce head-to-toe routine that delivers fast results. This partner workout guarantees to keep your muscles and your mind engaged from start to finish. You’ll shed fat and sculpt firm muscles while moving back and forth nonstop between strength exercises and cardio bursts.

How it works: Warm up for five minutes on a treadmill at an easy pace, jog in place, do low step-ups, or jog around the block. Then do one set of each of the following partner workout moves in any order, changing it up every time. Rest only as necessary, and after every third move do a cardio interval (see the final slide for a list of “Cardio Blast” ideas for this partner workout). If time allows and you’re feeling supermotivated, add in a few more rounds of strength moves and cardio bursts.

10. Partner Workout Cardio Blasts

Sprints

Run or walk fast for 30 to 45 seconds, then recover for the same amount of time. Choose an intensity that’s challenging. You have to do only three of these sprint intervals, so make them count.

No treadmill? No problem! Walk or run outside or jump rope for 3 to 4 1/2 minutes, hopping faster and then slower. Jumping jacks also work.

Hill climb

Walk or run at a 1.0 incline (choose a moderate-intensity speed) and increase the incline every 30 seconds. Repeat for 3 minutes (you should be close to your workout max), then reduce the incline every 30 seconds.

No treadmill? No problem! Repeat Challenge 1 or, holding a 5-pound dumbbell, do step-ups on a bench for 6 minutes, increasing the weight or the height each minute.

One-mile time trial

Run or walk (or do a combo) as fast as you can for one mile. Take note of how long it takes so you can try to beat it the next time.

No treadmill? No problem! Do it outdoors or jump rope for 8 to 10 minutes, counting revolutions per minute.

Insert one of these cardio bursts every three moves of the partner workout to torch extra calories.
