Question: what is the waist size for 30"
Document: Great inexpensive belt. Has definitely helped with my lifts. For reference, I have a 25&#34; waist and pull the belt to its smallest possible size.
Lenght is excellent for my waist size (if you're waist is 26 to 29 inches, this should be perfect) I use it twice a week on my leg workouts, I have no regrets.
Great product. Fits great. I ordered a medium could've gotten a small. But still fits fine, just has to wrap further around waist. I wear a size 6 in jeans.
serves the purpose for crossfit lift days.I'm a size 6 jeans and ordered a small. the strap is very long and wraps half way around my waist. the color is an attention grabber because its different from all the other brown or black belts in the gym.
I'm a muscular athlete (endurance and cross fitter) 5'2.5&#34; and 155 lbs with a 33&#34; waist. The SMALL is perfect. It fits well with extra room. I read reviews of others who say the cut is made large and recommended that consumers purchase down a size.
I like it, but it does slide a bit. I don't think it has anything to do with belt. I have pretty small waist and normal hips. When i tighten it lower to support lower back, it slides up a bit during squats. But overall i like my belt, should have ordered extra small though ( i'm size 4).
So ladies, I highly recommend going to the store and purchasing a measuring tape. I have a 28 inch waist and I got the small size. I do not recommend getting the small if you have the same measurent because the small wraps around my entire waist and sticks out a little on the side. Luckily my mom is in need of a belt so I was able to hand it over to her.
I am 5'3'', 130 lbs, and fit the measurements for an XSmall (My dress size is a 2 if that helps you visualize). When I received the XS I was able to fit it around my waist but it was VERY snug. I exchanged for a small which fits much better. Other reviews state that the strap varies greatly from XS to S and I agree - definitely go bigger so you have wiggle room and are more comfortable.
I am not really used to the lifting belts but I would have liked a some kind of shape on the sides, slightly curved because I felt it too wide on my side of my waist also felt the material a bit too thick. It was also a bit small on me. I got the XS, my waist is 24 1/2 inches, I am 5'4&#34; 119lbs. I think the small size would have fit better. The quality seemed good, the material was good.
Pretty and does the job too! What more do you want? Superb quality and perfect design for my little waist.
