im in the same boat as you with the injury.. took a nasty fall one night but actually broke my ankel and fracture my foot. Ive been on crutches for the last 8 weeks
if you have wii fit they actually have alot on strength training and yoga that you dont need to be on your feet for. Also my boyfriend is in the army and taught me a few exercises, i do them with one of the big exercise stay balls to make them more intense. but basically the first one i do he calls the jackknife
lay on your back completely straight hands streched out above your head holding the ball... crunch in and bend your legs and the needs and bring it up to your chest while your lift your arms with the ball down to your feet... hard to explain but when your in positon you should look like your almost crawled into a ball.... when you go back to starting position dont let your feed tough the ground.
next one is leg lifts
lay on your back and life your legs a few inches off the ground.... then (i dont know what he goes by but) a few seconds later lift your legs straight up to be in like an l shape then a few seconds later lower your legs back but dont touch the ground
the next one is "flutterkicks" ( gotta love US army)
this is painful to me, not cause of my injury though lol, you lay flat on your back, lift your legs a few inches off the ground.. keep your hands at your side and kick your legs up and down almost like your swiming... he tells me when its getting too difficult to go into a bicycle position for a min in between, like just stay laid on your back and move your legs like your pedaling a bike. ( he has me do these for 10 minutes so the bicycle break is definantly needed!)
and then actually just last night i was watching that new kristie alley reality show and saw her training having her do things that i could do with one leg. both involving an exercise ball if you dont have one get one there awesome!
but he had her have your back on the ball feet stationed on the floor (which i can do now cause there is nomore pain) and he just rolls his hips like you would do if.... your were doing a hula hoop.. just on the ball and slower lol works your abs and obliques.
and then just push ups with your legs on the ball and arms holding you up. and then always your stomach can be on the ball balancing while yuo lift 3-5 lbs dumbells.
hope this helps... goodluck & heal fast... iknow crutches are a pain in the
god bless
