When CM Punk, real name Phil Brooks, announced at UFC 181 that he would be making his UFC debut in the future, he also revealed that he was still looking for a training camp, but was looking at several high profile gyms.
Here we can see Brooks alongside top ranked Bellator light heavyweight King Mo, UFC heavyweight Roy Nelson, and JiuJitsu ace Rener Gracie.
