prowaist™ - Sweat Sauna Neoprene

I was skeptical about the whole "sauna" thing, but the neoprene really does trap heat — I'm drenched after a 20-minute walk. It stays put through squats too, no rolling down at the waist.

Wore this neoprene trainer during my morning runs and my core felt noticeably warmer within the first mile. The material traps heat exactly like a sauna suit should, and I'm already sweating way more than usual.

The neoprene really holds its shape during squats and lunges without rolling down, and you can feel the heat building in your core within a few minutes. I was skeptical about the extra sweat, but it definitely makes me work harder through the whole session.
