🔥 Did you know? Survivor 2.0 challengers get 18 sauna visits throughout the challenge! 🔥

That gives you plenty of chances to experience it for yourself and see why so many people love adding sauna time into their routine.

Whether you use it to unwind after class, loosen up, relax, or simply take a little time for yourself, those visits are a great way to explore the benefits firsthand.

💪 18 visits. 6 weeks. One more perk of taking on the challenge.

If you’ve been curious about the sauna, this is the perfect excuse to try it!
