On Thursday (March 14), Mike Tyson shared footage of the first day of his training for his upcoming fight against Jake Paul. 

Tyson told viewers that it was "Day one and the fun has just begun," as the former heavyweight champion sported a huge grin. Tyson has yet to publicly address the fight or offer a comment, but despite the 31-year age gap between the fighters, many are betting on Tyson to win. 

One of those people is Chuck Liddell, who told TMZ, "As soon as Tyson hits him, it's over. The last thing to go is power. If he hits him, it's over. If you've seen Mike, he still hits."
