Let me start by saying this shaper is no joke when it comes to making you sweat. I wore it for my morning runs, and within 10 minutes, I was dripping like I'd been in a sauna. The neoprene material really traps heat, making my usual 20-minute run feel twice as intense.

The sizing is tricky though - I followed the advice to size up twice, and while the torso fit perfectly (great for flattening the tummy), the arms were oddly mismatched. One sleeve felt snug while the other had extra room, which was strange since my arms are pretty symmetrical.

As someone with a larger bust, I appreciated that the top part stretched comfortably without feeling restrictive. The material itself is surprisingly lightweight for how much heat it retains. It moves with your body during workouts without riding up - a big plus when you're doing high-intensity exercises.

After three weeks of use, I've noticed better definition in my waistline. Just be prepared to drink extra water because this thing will dehydrate you fast with all that sweating!
