Well...just wanted to say that the doctor cleared me for exercise. He said that the artery shouldn't have any problems holding up to intense stress: sprints, intense metcon, heavy lifts, etc. I explained to him crossfit and he said, "no problem."
So, my welcome back workout today was 15 9 ft. slosh pipe front squats, 40 jumping pullups, 10 ring pushups (I'm very weak right now), and a 400 meter hill run. Three times!
It felt good to get back into it. I didn't push it too hard and my body didn't yell at me, so I'm happy. Now's the slow progression back to some form of "fit."
Thanks for all the help,
