Max Holloway Gains Size Ahead of McGregor Showdown

Max Holloway adds solid muscle for his July 11 welterweight clash with Conor McGregor, showing a natural bulk-up that could reshape the fight dynamics.

On 19 Jun 2026, new footage released of Max Holloway sparring former welterweight champion Jack Della Maddalena. The 33-year-old looks noticeably larger, but the added frame feels functional rather than forced. This visual cue arrives as the UFC confirms a July 11 bout at UFC 329, marking Holloway’s first official appearance in the welterweight division.

How did Holloway’s size change?

Holloway’s growth has been incremental. Over a decade in featherweight, he already tipped the scales at the upper limit, yet his recent regimen emphasizes lean mass. The sparring video shows broader shoulders and a thicker neck, yet his movement remains fluid. Analysts note that unlike some fighters who appear bloated after a rapid jump, Holloway’s added weight seems to complement his striking rhythm.

Why does the size jump matter against McGregor?

Conor McGregor, returning after a five-year layoff, will also compete at welterweight. McGregor’s power has always been tied to his size, and the matchup now promises a stand-up war. Holloway’s cardio, historically unrivaled, will test McGregor’s stamina. If Holloway can maintain his high output while carrying extra mass, he could out-pace the Irishman, whose recent interviews suggest mental readiness but no recent ring time.

What challenges could the new weight present?

Moving up a class never comes without risk. Holloway struggled against larger lightweights like Dustin Poirier, where the extra reach and power exposed defensive gaps. The welterweight division features fighters who regularly land heavier shots. Holloway must adapt his defense to a higher-impact environment while preserving the speed that made him a featherweight champion.

What’s next for Holloway after UFC 329?

If Holloway secures a win on 11 Jul, the victory could cement his status as a multi-division star and set up future high-profile bouts. A loss would likely prompt a reassessment of his optimal weight, perhaps a return to lightweight where his frame sits more comfortably. Regardless, the size jump adds a fresh narrative to a rivalry that began in 2013 when a teenage Holloway fell to McGregor in a featherweight clash.

The fight will be the first major test of Holloway’s new physique. Fans and bettors alike are watching to see whether his natural bulk-up translates into tangible advantage or simply adds another variable to an already complex showdown.
