Core Heat Training Suit (2-Pack)

You can't control the weather on race day. But here's what Pros figured out: you can control how your body handles it. While most athletes pray for cooler temps and train in comfort, the Pros are starting to train year-round with intentional heat exposure.

Why? To build an oxygen-carrying and heat management advantage that works in ANY conditions.

The CORE Heat Training Suit is like a portable sauna—a disposable polypropylene suit that turns your indoor trainer or treadmill into a heat chamber.

How Heat Improves Performance

The science is simple: heat stress triggers your body to produce more blood plasma, which then signals production of additional red blood cells. Over a few weeks, your blood's oxygen-carrying capacity increases. Research shows this translates to improvements in VO2max, lactate threshold, and power output—even when racing in cool conditions. Not only that, it teaches your body how to sweat more effectively.
