you can do it, even if its a few stairs at a time. grab it from the font (display side) and get your hands around the lower sides and keep your back as straight as possible. put it on the floor and squat. grab around the lower sides and try to stand a bit. use your legs NOT your arms/back. take it up a stair or three and put it back down and rest for a a few seconds. repeat till its up the stairs. flex your stomach muscles for added stability.

*if your back hurts, STOP!*
