Get better soon man. I am currently recovering from the worst cold I can ever remember. Went to a WWE event with 50K people and knew it was likely I would get sick. Never thought it would be this bad though.
This is why I just avoid quads all together. Some people love pinning them but not for me. I do get it though, easy to see so might be easy to pin, but I always got pip so just stuck to delts and glutes.
