Well, there's one thing we absolutely know about Roman Reigns' physique. He has giant, well-defined arms. However, what about his hernia surgery, and still wearing the SWAT gear is a way to hide post-surgery scarring. Maybe, due to the surgery he just can't work out his mid-section and legs like he would ideally want in order to allow them to match his arms. This is entirely possible, and in many cases would make everything he's done in the ring over the past six months completely remarkable.
