Watch: St-Pierre shows off his middleweight physique

It looks like size won't be an issue when Georges St-Pierre makes his 185-pound debut.

GSP posted a video on Facebook to give fans a glimpse of his training, as well as his bigger, bulkier physique. Widely regarded as the greatest 170-pound fighter ever, St-Pierre will enter uncharted territory when he challenges UFC middleweight champion Michael Bisping later this year.

St-Pierre's sponsor Hayabusa also uploaded a clip in which you can see more of the fighter's new look:
