Amazing and very high quality. Fits great; doesn't slip too much. Almost the same ones that they use in PT. Workout Review: +Straps are extremely comfortable; very fitted. +Cuffs are nicely designed; great for squats/running/stair master - After intense sweating, you can feel the straps start to slip, which is kinda a bummer. To be fair, they only started to slip after I had done stair master and 4 sets of weighted squats. I was sweating like crazy and that is when they began to slip. I'm thinking some baby powder should help fix that up, though. I'm positive that this is the best brand available for K-bands, and I think it's great for PT and to help increase functional strength for sports. I'm sad to say that one of the green bands snapped after an hour :/ I'm hoping the company has a small fee for replacing it or will just send a new green band and won't make me buy a whole new set. Used the red bands instead and they seemed super sturdy; endured a lot of lunges and squats. I think that one green band was just a dud. Overall fantastic​ set though! Would def buy again! --UPDATE--- -Company sent a replacement within a day or so. Red bands have still been working great--no snapping even when I do squats, power thrusts, stairmaster, and lunges. Green bands seem pretty sturdy, no tearing or signs of wear. I'm assuming if the red band still hasn't snapped while I'm doing these activities then I will be good to go with the green bands.

Amazing product! Ladies if you are looking for something to step up your booty workout this is it!! Super resistant and easy to use. Much better than resistance bands made of plastic that keep breaking and rolling down. Read more

took longer to get it. But will buy more. Already recommended it to people who saw the results from my speed and jumping abilities. And will be using it in my new dryland workout videos. Read more

You just have to get the hang of adjusting them in a way that matches the other leg. If one leg is not adjusted like the other one, then you won't have a balanced workout. These are really great, very durable despite the plastic rings on the bands themselves (the straps have metal rings). You can use just one band or use both (one in front-one in the back). I recommend these as they are a great way to train your legs and glutes without having them slip up (if you fasten them to tightly you may feel some pain in your thighs as is expected). it's about playing around until you find the right adjustments for your comfort Read more
