I was skeptical about the sauna effect, but the heat it traps during my cardio sessions is no joke—I can feel my core working harder and my flexibility has actually improved since I started wearing it. It’s snug but breathable enough to keep me moving through a full workout without chafing. Perfect

The waist trainer definitely amps up the heat during my cardio sessions, and I can feel the increased flexibility when I stretch afterward. Only gripe is the top rolls down a bit during squats, but it's still a solid addition to my routine.
