For what he's calling "The Mayweather Experience" boxer and promoter Floyd Mayweather is planning to open up his gym this American summer. For $650 USD per two-hour session, fans get use of his facilities and personal trainers for a first hand experience of his day to day preparation for a fight. Although it doesn't feature Mayweather himself, you may be able to see him pop in as he does actually use the gym for his training. So while the price may be a tad steep, for some mega fans it's definitely worth it.
