i just started on wii fit yesterday, i have had a spinal fusion and knee reconstruction on my right knee. i am considerly weak on right side, balance is pretty bad (its been 8 months since the knee surgery and 2 years since fusion) when i finished my session which was mainly yoga my back was pretty stiff. i'm just concerned it might not be suitable for me i certainly don't want to put any stress on my back, any feedback would be welcome, should i check with my doctor before i do anymore exercise or is there a beginners program?

wendy.

Definitely check with your doctor. If you have a medical issue you should always check with your doctor on starting exercise.

In general just take it easy. Start off doing a little bit and gradually work your way up. It takes time to build up muscle and you need to let your body adapt.
