Ron “Boss” Everline has made personal fitness and training his life’s work. Coming from a pedigree of football elites, out of Missouri City, Texas, the NFL was the biggest dream he never lived but has yet to regret.

What once began as a favor to a middle-age, hopeful mother that needed to lose weight so she could become pregnant, has become an entire brand— Just Train. And Boss, the once ambitious athlete who could never be outworked, became the sought-after personal trainers to the world's one-percenters. His ability to transform from a fitness need to a lifestyle want for clients that include A-List celebrities like Kevin Hart, Sean ‘Diddy’ Combs, Matt Barnes, and Fortune 100 CEOs have positioned Boss as a fitness elite.
