We're just months shy of the 16-year anniversary of Alan Shearer retiring from football but the Newcastle legend still looks in fine fettle.
Now 51, Shearer understandably isn't the athlete he once was but after partaking in a 30-minute HIIT session, it's clear that the base level of his underlying success on a football pitch remains the same.
Shearer is an ambassador for Speedflex and their new concept workout called FORTIS, headed up by CEO Paul Ferris.
Aside from leading that operation, Ferris was a former footballer for Newcastle - before injury curtailed his career - as well as a physio for the club.
