I'll have to give that a try. Our studio bought a frame trainer, but it's too small for me.
Please do not use that devise.
I saw two people have serious accidents with that kind of devise. One fell backward and cracked open his skull and the other fell forward and broke his nose. They were strapped in and not able to break their fall. The reason I used rope and sticks was because if I were to fall, then no harm done.
