Upgraded to 410 lbs.... how to.
on January 31, 2015
well made, and with a little warranty voiding custom work, can be made to work with the 310lb and 410 lb upgrade kits. See my pictures in the customer uploaded pictures section for my instructions on how i did it. i dont know how safe this is, so do this at your own risk. it works fine on my bowflex though.
