;s not clear what you want your design to do. It is preferable if you tell us your wishlist of leg exercises you want to do with this machine and which muscles you want to develop with this machine. Then we, designers, will create one for you. You review each of our designs and provide feedback. A random Designer will eventually create a functional exercise machine that meet you expectations. You can then follow up with that designer, informing him or her of any upgrades or modifications you would like to make to his or her design.
;t this more of a standing leg curl machine than a standing leg extension machine?
. Hi Michael, you are correct with all your analyses, except for the machine resembling a cross country skiing motion. The motion is this. Standing leg extension of the quad. It will be accomplished by bending one leg, while standing up. That leg will have a foot roller in on the toe of the shoe and two shin pads sandwiching the shin. At this point, the individual will extend/ push the lever forward do that the leg is in a fully straight position at the climax of the movement. Think of the leg swinging from a bent position to a straight position.
chaniago, yes that is correct. Square not circular.
