Just started another round of Insanity. Day 2 brings a lot of soreness in the back and glutes. But I stuck with it, hit play, and did Plyometric Cardio Circuit, followed by a 3 mile run. Once finished, I treated myself to some skillet baked tilapia, sweet corn soup, and coconut water. Now, rest for a few hours and try to make it to jiu-jitsu.
