Will Brian Johnson be able to dunk at 49, according to Sam Parr and Shaan Puri?

Shaan Puri doubted that Brian Johnson will manage to dunk, arguing that jumping depends more on coordination than on strength training. Sam Parr said most people can train to around a 28-inch vertical and that the hard part is technique such as the approach step, and the two settled on a Five Guys burger bet. Shaan said Johnson chose dunking as a performance benchmark because it draws more attention than blood test results.

• Brian Johnson's own post said he needs a 39-inch vertical, above the average NBA player's 35.5 inches.
• Jason Kelce's six-month dunk attempt came up as a comparison, with the hosts noting he is 6 ft 4 in and a former professional football player.
• Shaan Puri said his own goal of dunking this year is untouched and depends on losing about 25 pounds.
