AB (Alfie Buttle)

Alfie Buttle, universally known as AB, is a British fitness content creator born on August 12, 1999. He launched his YouTube channel in 2018, initially focusing on gym content, workout tutorials, and fitness lifestyle vlogs. What started as a personal fitness journey documented online evolved into one of the UK's most authentic fitness content channels.

AB's rise in the YouTube fitness space came through his genuine approach to content creation. Unlike many fitness influencers who present unrealistic expectations or promote questionable supplements, AB built his brand on authenticity, realistic goal-setting, and transparency about both successes and struggles in fitness.
