Stuart Broster, chief executive of Anytime Fitness UK, will step down from his role in April 2020.
Broster, who was named CEO in August 2017, recently relocated to Scotland and outlined his desire to set up his own consultancy business.
During his tenure, Broster has overseen Anytime Fitness UK’s growth to become the second-largest private gym operator in the UK, the brand’s repositioning from "convenience to coaching" and the launch of a new gym design.
He will be replaced by Neil Randall, the current chief operating officer.
Randall has been heavily involved in developing and implementing Anytime Fitness UK’s future strategy.
In a statement, the company's board said it believes Randall will "provide continuity to the great progress made under Broster’s leadership".
“Neil was the outstanding choice as Stuart’s successor and the Board believe he is the perfect appointment for Anytime Fitness UK at this time,” said Andy Thompson, Anytime Fitness UK chair.
"Since joining the business in 2018, Neil has been heavily involved with all aspects of the business and has enjoyed outstanding success across strategy, marketing and supporting franchise network.
“With Neil knowing the business inside out, and forming strong relationships with staff, franchisees and suppliers, this gives the Board reassurance and confidence in a seamless transition when he takes up his new role."
Randall will take up the position of CEO on 1 April.
“Having known Stuart for a number of years, I’ve learned so much from him and would like to thank him for his support on both a personal and professional level," said Randall.
"He has made an incredible impact on Anytime Fitness UK, overseeing a significant growth and transition period for the business and I’m excited to continue the journey and build on the great progress we’ve made under his leadership."
