The most popular machines at any gym are the elliptical, stationary bikes, and treadmills. Why? I think it’s because they show you the amount of calories you’re burning. FYI—you don’t need a machine to burn that many calories! These 5 exercises will get you the most bang for your buck in burning calories and hitting several muscles at once. Best of all, you can do them at home without a machine. (NOTE: All the calorie estimations are for a person who weighs 155 pounds.)

1. Plank drag (with towel). Get into a plank position, with your hands right underneath shoulders, with your abs engaged and a flat back. Also, you’ll want to place a small towel under each foot. On a hardwood or linoleum floor, drag your body from one side of the room to the other, pulling your body weight by using your arms to move around. One trip across the room, both there and back, counts as one round. Repeat this three times. Check out the image for details.

2. Burpees. Burpees are the go-to full body workout. Get into your plank position, then “jump” your knees towards your chest. Next, jump up, raising your arms in the air above your head and pointing your toes. When you land, go back into your knees-at-chest position and kick your legs back out. This one is INTENSE – do as many as you can a day.

3. Jump lunges. Start with your feet together, elbows bent at 90 degrees, and then lunge forward as shown. Next, jump straight up as your raise your hands to the ceiling (but still keep your elbows bent!) then land in a lunge with your opposite foot forward this time.

4. Renegade row. You’ll need two hand weights for this one. Get into your plank position, with your weights in your hands that are supporting you. Lift one arm against your body, so your forearm aligns with your back and your elbow is at 90 degrees. Hold for 2 counts, then lower back down to start. Repeat on the opposite arm. Check out the image for details.

5. Squat to press. Grab two light hand-weights and stand with your feet shoulder-width apart, elbows bent 90 degrees and your palms facing forward. Get into a squat position and hold for two seconds. Next, push through your heels to stand up straight while raising your weights towards the ceiling.
