Not gonna kick you in the butt, just a hug - I used to run regularly, but my weight gain in pregnancy really knocked my knees out and I haven't been able to even walk regularly since then - 4 years now! But how about using it for motivation, as I am now: really hoping that more weight loss will make it so my weakened joints can tolerate the load!
Big hug from me too. I used to run and I miss it terribly. This last pregnancy (and maybe the one before it as well) really did a number on my knees. I signed up for a 5K a couple of weeks form now and there is no way I can run it. I will walk which stinks, but I hope to be able to run again. I need to lose about 40 pounds and do some serious strength training before I will be able to run much.
