Stamina X Adjustable Ab, Back & Core Strength Training Bench - Hyperextension & Sit-Up Fitness Equipment for Home Gym Workouts - Perfect for Full-Body Exercise & Core Strengthening

well its not the greatest bench ever made but its a nice bench, quality seems to be pretty good overall, the price is not bad, its light weight and it folds up so you can get it out of the way. if all of those things matter to you this is a good bench. if you want something that is really heavy duty this is probably not the bench for you..this bench is plenty sturdy for back extensions which is why i wanted this bench. i had a 210 lb person on it this morning and it held their weight fine for back extensions.when you start trying to do things like chest dips where i fold my legs back and my full body weight is on the handle bars is where i see a issue with this but again its a light weight product so i cant hold it against it, when i do that i can really feel some slight flex in the bench and i am about 150lb so i am not sure i would use it for anything where you are putting allot of body weight on the handle bars. almost makes me want to give it 4 stars but i do not plan on doing that kind of thing any ways since i already have a dip station so this thing works perfectly for what i bought it for.i have a bad/really weak lower back after a injury several years ago and doing little mini back extensions is about the only exercise that really seems to be hitting the muscles that need to be strengthened, i wish i would have tired this exercise a long time ago, started doing this exercise about a month ago at the gym that i work at on my lunch break and my lower back is feeling stronger than it has in a long time., doing dead lifts and squats with body weight or light weight has helped out pretty well, those both hit lower back a little and really trying to strengthen my core has been of some help too but nothing beats a hyper extension or back extension, what ever you want to call it for strengthening your lower back when you not able to lift heavy weights so i decided to get one of these benches so i can use it at home.
