Overall, I'm thrilled with this machine. It's the most comfortable form of exercise I've ever found, even when breaking a sweat. I'm 72, female, and have been quite sedentary for a LONG time. I am taking a chance that this will finally help me get the exercise I need. One thing, though, is that since I currently weigh nearly 300 pounds, and I "spread" a lot when I sit, it's impossible for me to use the "lower grip" so that I can do more work on my arm muscles. The gripping part of the handles is so long that they poke and rub against my hips in the down position, which hurts. That's quite disappointing. Shortening the length of the grips pointing inward toward the body by about 2-3 inches would probably make a huge difference. I've resigned myself to having to use the machine only with the "upright grip" over time, until I actually start losing inches in my butt and hips so that the grips no longer poke into me when I switch to the "lower grip." It would be really great if these handles/grips could be replaced with alternative grips that aren't so long. Maybe you could design an alternative handle/grip replacement part? I REALLY want to work on my triceps, but it's impossible at my current size. I do hope something can come from this suggestion, because I can't afford to buy a whole new redesigned model. A redesigned handle grip would be perfect!
