Sure, I'm happy to share. I find yoga to be super helpful in maintaining flexibility-- I get the most out of coupling it to strength training exercises both the day before and after. For the hip rotator issues I have been doing banded clam shell exercises on a slow ten count, leg lifts, and banded multi-directional hip flexion/extension exercises (front, lateral, and back). Core strengthening helps too-- for example, in a bridge pose place feet on an exercise ball with knees flexed, then let feet extend forward until the ball ends up behind the knees. Pull knees back in and repeat 10x while maintaining bridge pose. This lets me strengthen both my core and the back of my legs nicely.

Post weight loss I can do all kinds of things that were not sustainable longer than a few seconds before-- walking and running, bike riding, yoga, planking, sit ups, tennis, etc.. In general my balance has been much better, and my agility has increased dramatically. I still move as though I need to account for the "jiggle factor" out of habit, but when I concentrate things move smoother and faster.

I have a suspicion that some other parts could use some help-- particularly my back and shoulders (for posture). I'm very curious to know about upper body PT post weight loss if anyone has had some.
