I tried HotWorx

 working out in a sauna? blurry pics, but a great workout. 

Some of the girls I work with are OBSESSED with HotWorx, so of course, I had to go with them one time!

The basic set-up: 2 or 3 people in a sauna with a screen at the front. The employees at the desk will help you get a proper mat and towel and get everything set up. The instructors pre-record the workouts on a set, and then the videos play automatically at the correct times in the sauna. The studio is open 24/7, and you can sign up for classes on an app. As far as I can tell, most locations have about six saunas. HotWorx offers all kinds of workouts, including yoga, barre, HIIT, cycling, and treadmills. Classes are 15 or 30 minutes, depending on what type of exercise you’re doing.

What I liked: It is quick, easy, and effective. I did ISO, which is basically their take on yoga/isometric stretching (not really a flow, but a series of stretches.) You will sweat your heart out. Pro tip- being in the middle is the coolest, and you can change the temperature from the inside. Afterward, I definitely felt the burn and had pushed my abs to their limit. HotWorx advertises that because of the sauna, you will continue to burn calories after the workout.

Rating: 10/10- I absolutely loved it and would absolutely go back. I love burning lots of calories while stretching and doing abs because it is easy, low impact on my joints, and feels really effective.
