With his long-awaited test against Brock Lesnar at WWE Battleground drawing closer, WWE World Heavyweight Championship Seth Rollins chatted with MensJournal.com for a pair of Q&As about the benefits of CrossFit, what caused him to try the popular training regimen and his diet.

Rollins “bought in” to his own success and joined The Authority. From knocking rivals like Ambrose and Randy Orton out of action to staring down giants like Lesnar and Kane, Rollins has proved he’s a force to be reckoned with.
