These worked great for about 8 years of light use. Both straps broke simultaneously today and hit me we the carabineer. Fortunately I was on my back to a neutral position and caught myself rather than falling back to the ground on my back.Works well but feels cheap not the most comfortable materialsI figured from the pictures on the box that if I bought these things, I'd be ripped in no time, just like the people on the package. My townhouse came with a really nice pull-up bar, so I figured these would be a great addition, especially since the price was great. Installing them was a breeze, but that's where the positive experience ended. . . . . How do I get into these things? I mean, I can do three pull-ups, so I should be able to do one and get my arms in these. . . . . not the case. My three and eleven year old got to watch "Superdad" hang these things up and then flop around like a fish on a hook out of water trying to get into them. My three year old quickly quit asking to try them and walked away. My eleven year old stuck around to see if I could pull it off, which I did, but then said "good job dad" in the most non-convincing way when the struggle was so hard to get into these that I couldn't do anything but wonder how I'd get down.In all, if you can do enough pull-ups to call it a rep, and you a stomach that shows potential of being able to wash clothes on it, these bad boys are a great deal. As for me, I'll let them hang there till I can get that rep thing down.These used to work for about year. Then I went up in a crunch position this week while in the air hanging and both straps broke in the same spot at the exact same time. I fell on my back and had a chair below me that broke my fall and have some bruises but it could have been really bad and broke bones on this fall. These are trash and not up to par quality. I weigh 180lbs and the weight says 300lbs.These straps are great for doing core workouts without having to get down on the ground. Exercises are more impactful and less stressful on the neck and back-- gravity helps force proper alignment when paired with proper breathing.I like hooking my hand grasp on with my thumbs through the metal hooks, helps my arms to be positioned evenly within the straps too. Not the most comfortable but there is no impairment on functionality or ease of use.Key point for me seems to be the stabilization of whatever you're attaching it to, make sure it will support your weight and movements during exercise performance.These ab straps work perfect on my squat rack pull up bar. Ive only had them for a day but as a personal trainer I know a thing or two about exercise equipment and these will work just fine. No need to spend a ton of money. I looped the stap around my bar twice in order to shorten the straps so i could hang onto the pull up bar at the same time. I can easily hang from my pull up bar for up to 2 minutes but the straps help boost me up to where my feet dont touch the ground when they are straight allowing me to get a better abdominal exercise. And as for people saying the straps dig into them.... It will probably help looping it around twice and holding onto the bar too. Less pressure in one area. Also youll get used to it just like the bar used to hurt your shoulders when squatting back in the day. Id definetely recommend these straps because hanging leg raises are one of the best ab exercises you can do.I got these after assembling a garage gym. I purchased a I put them on my pull up bar and use them all the time to do abs!Easy to useI like it...Perfect ? thank you so much ?The "1UP Hanging Ab Straps" (also for sale here on Amazon) are MUCH BETTER than either "Perfect Abstrap" (not enough padding, skimpy flimsy nylon) and MUCH BETER than "DMoose Ab Straps" (not enough padding). The 1 UP straps, by comparison are WIDER (more comfortable support), have MORE PADDING (super comfortable!), and SUPER-TOUGH NYLON STRAPS, and HUGE HOOKS (will fit over ANY bar). SO, save yourself the grieve -- just by the 1UP Hangin AB straps!I'm happy with this. I have a permanent bicep injury that prevents strength training with it. Using this I'm able to do pull ups again and works as good as it should.I have no problem with comfort as some of the negative reviews have mentioned. The only issue I have is that it's not height adjustable so instead I use a bunch of carabiners to get it to a good height
