4-inch Ultra Low Profile Performance Slimline Black Weightlifting Lifting Belt and Back Support. Ideal for Crossfit, WOD, Gym and Lumbar Back Support

This was first time purchasing a belt and I wanted something affordable and good quality which is what I got. I'm 5', 105lb with a 24" waist and the Small fit perfectly. Used this for heavy back squats and had no problems with it. Good support and fairly comfortable, really satisfied with this as my first belt

Small fits perfectly (my waist is 27.5"); and my trainer said I made a good. Would have rated a five, but there was a slight chemical oder when I removed the belt from plastic covering. Even after airing before use, the chemical oder was there on my shirt (maybe was the reaction from my sweat), but I will continue to use the belt as is does support me when doing squats.

Helped me past a Plateau. I was stuck at 275lbs because I kept leaning forward and using my lower back. I knew it was a problem, but I couldn't correct it, dropped weight and worked my way back up, but I kept having the problem anywhere near 275lbs. This allows you to tighten your torso much more which eliminated my problem and I've increased to 295 in one month. This let me finish my workout and have my legs feel sore instead of my lower back. 4 inch works, but I plan to get 6 inch as well. The measurement is accurate from around your stomach, not your pants size.

Today I used the crossactiv weightlifting belt for the first time. I did back squats 155lbs. 2 sets 10reps w/o the belt. Then I did 3 sets 10reps with the belt & I notice I felt more confident & secure going all the way down without bending by back after so many reps completed. Even though it's not much weight but I felt more confident in doing more sets. I'm glad I made the right choice buying this weightlifting belt.

The belt slide up and down too much

Used it once to squat and it popped off under pressure. Not a belt I would ever recommend. I had to return it.

Well built belt

Works OK.
