Heavyweight boxing allows for a diverse range of body types and adaptability in fighting styles, making it a highly competitive weight class. Notable heavyweight champions include Mike Tyson and Deontay Wilder, each showcasing unique skills and strategies. The lack of an upper weight limit often leads to intense matchups where size and power can play significant roles in determining the outcomes of fights.
