Like others have warned, this weight bench is so small that people taller than 5'7" will have a hard time using it, if at all.Unfortunately, it is the area that most interested me, the leg extensions/leg curls, that was the most disappointing:A) I am 5'7", and the seat is barely wide enough to be useful, and not long enough to do the leg exercises comfortably, or even practically. I have to place a thick cushion, since the thighs protrude beyond the seat, which limits the weights you can use comfortably since they press/crush your thighs against the very edge of the seat when doing leg curls.B) As others have said, the bench is so low that your feet touch the floor at the lowest point of the leg extensions. I have to place a 2x4 underneath each of the two legs to elevate the bench more. You have to design your routine so you always keep your heels in the air, not letting it touch the end of the bench. Since I do low weight/high and varied reps, I can go around that weakness.C) The foam pads are barely long enough to fit your feet lift the weights. Your feet, or the pads, tend to slowly slide off with each repetition, and I often have to adjust my feet position on the fly. They (and the metal tube they are inserted to) need to be a few inches longer.Now, for the price (and the other reviews), I probably shouldn't complain too much. I knew what I was getting into. I simply couldn't afford at the time any of the other units at twice the price and more with the rare leg exercise attachment.What I will do in the future to ameliorate these drawbacks are the following:A) Get 2 in. x 12 in. x 8 ft. lumber (wider than 12" if available), bolts, thicker foam cushions, and some vinyl or canvas to make a longer, more comfortable seat, so my legs aren't hanging in the air at the end, and I can safely add more weights. The padded back is adequate enough as it is for me.B) Get longer foam foot pads rollers, but not so long they go too far beyond the tube support. I wish I knew how to weld things.I can't fix the height so propping it up with 2x4s will have to do.
