AS Conor McGregor, a star in MMA, prepares for his first professional boxing contest, which just so happens to be against Floyd Mayweather, he has been issuing photographs from his training camp.

It’s hard to read much into the photos but in the latest dispatch, a snap of McGregor throwing an uppercut, he expounded on his theories of boxing.

He wrote: “In order to have complete freedom in your shot selection and direction, you must first gain the ability to disconnect each limb from the body safely.

“This is a right hand uppercut. But notice the separation in the shoulder joint. From the rotator cuff, to the clavicle and collar bone. The entire joint has complete freedom and separation.

“That whip of a shot is free to go in any direction.

“The same rules apply for every part of the body. Freedom in the body equals freedom in the strike.” He signed off, “Yours sincerely, the greatest.”
