Hey Hip, congrats on the socks! amazing how some small things just are great accomplishments. Be careful with the leg presses. I have been fine with some leg press machines, especially the one at PT, but some have strange angles and have caused me pain (felt like a slight pull) on the groin muscle area. Took a couple of days to clear up, so be careful with that - seems like my thigh muscles are just fine, but the muscles around the affected area neeed to catch up - we need to let them.
I still do leg presses, just do them with a lower amount of weight. Upper body stuff is fine, staying away from free weights for now, seeing as I would just be tempted to do my old stuff. Nautilus / others for me for the near future.
I'd really suggest a foam roller for when you start stretching. It works on the IT band and later on the incision itself. I've also gone to an understanding massage therapist (working to be a nurse) who continues what the PT started - massage on the scar itself to loosen up anything binding there.
I also do a lot of balancing. This started in PT - first balancing in shoes on the floor for 30sec. Then barefoot balancing for the same amount of time, proceeding to balancing on a small pillow or foam pad to make things more challenging, then taking a ball (volleyball or soccer) with both hands and make figure 8's in front of you while balancing on the pad/pillow for 30 seconds. I do this in front of the TV frequently, helps those little stabilizers.
I'm starting to do some martial art stances, little by little, but that's for a smaller audience.
