Infrared vs Traditional Hot Pilates: What's the Difference?
Hot mat Pilates and infrared Pilates are not the same thing. Here's how the two types of heat compare — temperature, sweat, benefits and safety — and how to decide which class to book.

Search for a "hot Pilates" class in London and you'll find two very different experiences hiding behind similar names. Traditional hot Pilates heats the air in the room — often to 32–38°C — while infrared Pilates uses radiant panels that warm your body directly, at a much gentler room temperature.
The difference sounds technical, but it completely changes how a class feels, who it suits, and what you get out of it. Here's an honest comparison from a studio that teaches heated mat classes every week.
How Traditional Hot Pilates Works
Traditional hot Pilates borrows its format from hot yoga. The room is heated with convection heaters — the same way a sauna warms up — so the air itself becomes hot and often humid. Your body heats up because everything around it is hot.
The experience is intense. You sweat heavily from the first few minutes, your heart rate climbs quickly, and much of the challenge comes from simply tolerating the environment while you work.
Some people love that intensity. But it has trade-offs: the heat can compromise your form as fatigue sets in, and it makes classes genuinely unsuitable for anyone who is heat-sensitive.
How Infrared Pilates Works
Infrared panels emit radiant heat — the same wavelength of warmth you feel from sunshine on a cool day. Instead of heating the air, the panels warm your muscles and tissues directly.
The room in an infrared Pilates class stays at a comfortable 25–28°C. That's warm enough to feel enveloping and to loosen your muscles, but nowhere near the challenge-by-endurance temperatures of a traditional hot class.
Because the air stays temperate, you can breathe easily, hold your concentration, and keep the precise control that Pilates is built on. You'll still sweat — but it's a steady, cleansing sweat rather than a survival response.
The Key Differences at a Glance
| Traditional hot Pilates | Infrared Pilates | |
|---|---|---|
| Room temperature | ~32–38°C, often humid | ~25–28°C, dry |
| How you're heated | Hot air warms your body | Radiant heat warms muscles directly |
| Breathing | Can feel heavy or stifling | Easy and natural |
| Sweat | Immediate, heavy | Gradual, steady |
| Focus | Split between exercise and enduring heat | Stays on precision and control |
| Best for | Heat-lovers chasing intensity | Flexibility, recovery and mindful work |
Which One Delivers More Benefits?
Both formats warm your muscles, and warm muscles stretch further and more safely — that part is shared. The difference is in what else comes with the heat.
Infrared heat penetrates deeper. Because radiant heat warms tissue directly rather than waiting for hot air to do it, your muscles reach a workable warmth without your core temperature soaring. That's why infrared classes are popular for muscle recovery and easing stiffness.
Form holds up better at lower air temperatures. Pilates is a precision practice — the benefit comes from doing movements well, not just doing them hot. At 26°C you can keep your technique sharp for the full class; at 38°C, most people's form degrades as fatigue and dehydration build.
Recovery is faster. Clients typically leave an infrared class feeling energised rather than wrung out. That matters if you're training several times a week or fitting a class into a working day.
Safety: Who Should Choose What?
Traditional hot classes place real demands on your cardiovascular system. If you're pregnant, have a heart condition, experience low blood pressure, or simply know you don't cope well with heat, the gentler environment of infrared is the safer starting point — though you should still check with your doctor if you have a medical condition.
Hydration matters in both formats: drink water through the day before class, not just in the hour beforehand.
What We Teach at Aligné
At our Great Portland Street studio we chose infrared for our heated mat classes deliberately. Our clients come to Pilates for controlled strength, better posture and flexibility — and infrared heat supports those goals without turning every class into an endurance test.
Classes are small, so your instructor can actually see and correct your form — which, in a heated class, matters even more than usual.
Frequently Asked Questions
Is infrared Pilates as effective as hot Pilates?
For the goals most people bring to Pilates — flexibility, core strength, posture and recovery — yes, and often more so, because your form stays precise for the whole class. If your main goal is the feeling of an extreme sweat session, a traditional hot class delivers more of that.
Will I still sweat in an infrared class?
Yes. The radiant heat raises your muscle temperature and you'll build a steady sweat as the class progresses — most people are pleasantly surprised by how much, given the room never feels stifling.
Is infrared heat safe?
Infrared is simply radiant warmth — the same type of heat you feel from the sun, without UV. Our classes run at 25–28°C, well within a comfortable range. As with any heated exercise, consult your doctor first if you're pregnant or have a cardiovascular condition.
Do I need experience before trying a heated class?
No. Beginners are welcome in our infrared mat classes, and the warmth actually helps newer students reach positions comfortably. If you're brand new to Pilates, you might enjoy reading what to expect in your first class first.
