A lot can happen in two decades, Brock Lesnar can attest to that. The last 20 years have seen the South Dakota native try his hand at American football, mixed martial arts (UFC) and wrestling, all while looking after his body with the careful attention of an elite athlete.An image comparing Lesnar’s physical transformation from his 2002 SummerSlam debut to his present-day form has been shared by the Peacock Twitter account, emphasising his incredible ability to stay at the top of his game in the ring and in terms of his body aesthetic.In the left side of the image, a 25-year-old Lesnar sports a military-style crew-cut, with the disciplined facial expression to match. His trademark enormous trapezius muscles are flexed and his biceps are bulging. A no-nonsense all-black outfit of low-cut pants, knee guards, wrist straps and studded boots add to his ominous look. To complete his armed service style look there is a lack of any body ink.Fast forward to the present day and a lot has changed.

Gone is Lesnar’s disciplined style which has given way to an-almost-Mohawk style cut to go with a beaming smile. No longer is he clean-shaven, with a bushy ginger beard forming around his jaw. Lesnar has, however, maintained his Demigod style physique as well as somehow appearing more toned, with abdominal muscles Anthony Joshua would be proud of. The wrist and knee accessories have been dispensed with and the tight briefs replaced with more relaxed black shorts.

Perhaps the biggest transformation in Lesnar’s appearance is the addition of tattoos to his upper body.

A trademark sword runs up his torso and towards his neck harking back to a time when he felt as though he was being held at knife point during his dispute with WWE in the 2000s.

Unseen in the photo is a large demonic skull inked onto his back, potentially hinting at his fighting persona. This body art feels a long way detached from early Lesnar’s military style and shows the changes he has been through inside and outside the ring.

On the face of it, Lesnar is still a man in the peak of physical condition, however, look closer and a lot has changed. 20 years is a long time, and it seems that 45-year-old Lesnar is in a much happier place than his younger self.

What's also remarkable is that back in 2002 and his SummerSlam debut he was taking on The Rock. Fast forward 20 years and last night he took on Roman Reigns. There's something poetic in that.
