Former Twitter CEO Dick Costolo took to his Twitter account this morning to reveal more details around what he is working on next. Costolo, who officially left the social media company in July 2015, is tackling a new startup in digital health and fitness.

Costolo said that his startup, which he co-founded with CrossFit trainer and director Bryan Oki, is creating software that can be used by fitness professionals, nutritionists, physical therapists and more to communicate with their clients, guide them, and motivate them to achieve their goals.

“The fitness industry is transitioning to a world of specialized studios and programs with a multitude of connected devices and software trackers. We’ve developed a system within this evolving landscape, and we believe we can scale this system with technology and deliver it to a massive audience,” Costolo wrote.

Costolo’s move into health isn’t particularly surprising. He’s known to be passionate about fitness and CrossFit.
