Thanks to Special K for sponsoring this video! Here are 5 things that suck SO MUCH after doing an intense workout. But as much as it sucks...I LOVE being sore!!! It's kind of like a badge of honor! It's like the sorer I am, the bigger the change signal, the bigger the honor :) I LOVE evolving and not staying stagnant. And, make sure you're feeding those change signals with nutrients like protein and iron! And guess what!? You can find that in Special K! Which scenario is you right now!??
