The best way to fix the problem at the top section of the frame, where your leg is too open is to buy some "thick" Skateboard knee pads. The ones I use are designed by RECTOR, they cost about $50.00 but make a huge difference. Powerisers were almost impossible for me to use before I got these knee pads. The knee pads rest between the round top section and my leg, with the strap tight in the back.
