How Many Calories Your Favorite Workout Classes Actually Burn

Group workout classes are great. You’re motivated by the overachieving people in the front row to work harder, but you also don’t feel super sh*tty about yourself because there is usually someone who’s just as lost as you. But even if you’re not perfectly coordinated (me in dance cardio classes), you will likely still be dying at the end of a class, if you’re doing it right. Obviously, not all workout classes are created equal, and some will burn more calories than others. So I did the research to find out if cycling is really kicking your butt, if CrossFit is really worth it, and more. Read on to find out how many calories workout classes burn. For reference purposes, I reported the number of calories burned for a woman who is 155 pounds. So your mileage may vary, but here’s a good reference guide to the calories burned in your favorite group fitness classes.

HIIT

Also known as high-intensity interval training, HIIT classes involve lots of sweating, heavy breathing, and typically burpees. As the name implies, they are structured in intervals of high-intensity workouts. Typically, you push yourself to the maximum for 20 to 90 seconds before taking a short break and doing it all again. Due to the intensity of the workout (say “intensity” again), you can burn up to 900 calories in an hour. The harder you work, the more you’ll burn. Either way, you’ll for sure need a shower and nap after this workout.

Kickboxing

If you want a major confidence boost, take up kickboxing. This high-intensity workout will test your balance, endurance, strength, coordination, and flexibility. Not to mention, you’ll feel like a total badass when you master a mean uppercut. A 155-pound woman could burn around 740 calories in an hour of kickboxing class. Speaking from experience, you’ll work legit every muscle in your body, and I can guarantee you’ll be so sore the next day. Have fun walking upstairs!

Cycling

Personally, cycling is my favorite workout. The high energy and fun music makes me forget about how much the instructor is kicking my ass. According to this calculator, you could burn 637 calories for a one-hour spin class working at mid-intensity (which means that you could still have a conversation). Personally, I can barely breathe midway through a spin class, let alone have a conversation, but sure.

CrossFit

Say what you want about the people who swear by it, but this workout is no joke, and you’re able to burn almost 800 calories in an hour (so I guess those bros are doing something right). It’s a high-intensity, constantly changing workout that involves exercises like push-ups, pull-ups, and squats. Honestly, I don’t feel like I need to explain it further—if you want to know more just go up to the nearest person you know who does CrossFit and breathe in their direction and they’ll tell you all about it.

Circuit Training

Circuit Training

This workout may be hard, but it is never boring. It combines a variety of different exercises to work different muscle groups that you move through with a short or no break in between. Your heart will be racing basically as soon as you start. In a one-hour class (or workout you do yourself, which I’m v impressed you are motivated to do), you could burn up to 547 calories.

Hot Yoga

Well for starters, it’s hot, which some people hate but I personally love. You sweat balls, which always makes me feel like I’m working 10 times harder that I probably am. The heat also helps you release toxins and loosens your muscles so you can have a deeper stretch. For an hour hot yoga session, you could burn up to 500 calories. You can also improve flexibility and reduce stress.

Barre

I don’t think I’ve ever left a barre class when my legs don’t feel like Jell-O. Even though I danced ridiculous hours as a child, these classes are very hard. In case you missed the trend, barre is a combination of ballet, yoga, and pilates poses and exercises to work muscles you never even knew you had (or at least, that’s the case for myself).  You can burn more than 400 calories in an hour class and tone your muscles. These ballet-inspired classes will make you feel like a classy ballerina.
