It’s hard to pinpoint exactly when everyone—from your favorite celeb to someone you literally or parasocially know—became a Pilates girly. (For me personally, it was the 2022 Met Gala when Lori Harvey credited the Pilates for her immaculately toned abs). The workout’s hold on the culture has remained unmatched, and for a while it didn’t seem like anything could take its place as the reigning “It” girl workout of choice.

But a quick scroll through IG or TikTok, and we’re slowly being fed video after video of a newer and hotter iteration that might take the top spot in our fitness journey. Now, we wouldn’t necessarily call this a replacement. Instead, think of it rather as an elevated take on a classic. Say hello to hot Pilates.

Pretty self-explanatory, hot Pilates is a form of Pilates that takes place in an infrared heated studio to boost whatever your fitness goals are. “In addition to being a low-impact activity that helps with flexibility, balance, and core strength, there are the mental benefits of exercise,” explains Alexis Colvin, MD, professor of orthopedic surgery at Mount Sinai. “Also, the heat is an additional challenge that is novel.”

What Is Hot Pilates?

As Eli Kaylin, instructor and founder of hot Pilates studio Fuze House, describes it, hot Pilates is a low-impact, high-intensity workout that is performed in an infrared heated room. Temperatures during class are typically set to 95 to 100 degrees Fahrenheit and you’ll perform the workout, which mixes traditional and contemporary mat Pilates movements, with props such as light weights, bands, and Pilates rings on a mat.

The Benefits

No matter which form of Pilates you take, Dr. Colvin lists increased flexibility, improvement in joint range of motion, and a strengthened core as the main health benefits of doing Pilates regularly. Studies show that it can also help reduce stress.

When you take hot Pilates, you get the added benefit from the infrared heat. “Not only does [the heat] increase blood circulation, but heat loosens muscles and increases flexibility, which also helps reduce the likelihood of injury,” says Kaylin. Studies also show that heated workouts increase your metabolism and burn more calories compared to non-heated ones.

The Downsides

But you still want to be careful in these high temps and hot Pilates may not be for everyone. Dr. Colvin cautions those with certain health conditions such as asthma, heart disease, low blood pressure, and low blood sugar or those who are pregnant to be careful when signing up for a class. The excessive sweating and high temperatures may cause dehydration and an increased risk of fainting. “If you have medical issues, be sure to get clearance from your doctors before starting,” she says.

Hot Pilates vs. Reformer Pilates

Other than the high temps, Kaylin says that the biggest difference is that hot Pilates is performed on a mat while reformer Pilates is performed on a reformer machine. Reformer machines are equipped with springs, straps, a platform, and a carriage system to give you resistance and intensity for your workout. Hot Pilates, by comparison, depends on your body to give you the same tension.
