Caullen Hudson

Hailing from Columbia, Missouri, Caullen originally moved to Chicago to study film at DePaul University, where he found fitness as a second career while working at the campus gym. Involved in team sports while growing up, his appreciation for the community and collaborative atmosphere in group training transferred into crafting creative programming for clients and participants. Now an established instructor in Chicago, Caullen has been training since 2012 earning American Council on Exercise (ACE) Group Fitness, Personal Training, and TRX certifications along the way. In that time, he has been featured in Thrillist Health and presented at conferences, such as the Midwest Fit Fest. Caullen specializes in high-intensity interval training (HIIT), anaerobic cardio/agility, functional muscle movements, and power/Olympic lifting. As a firm believer in effective conditioning coupled with “picking heavy things up and putting them down,” he blends his passion for athletic performance to produce an intense yet unique and dynamic workout experience. Encouraging everyone to “do what works for you, but make yourself work,” Caullen brings his energy, committed mindset, and obnoxious personality to ensure a fun and powerful workout.

Additionally, Caullen is a “double demon” of DePaul University receiving his masters in sociology in June 2017. When not leading a class or training himself, he can be found shooting films, podcasting, working on social justice campaigns, and most definitely not eating chorizo tacos…nope. Learn more at
