Firefighters, law enforcement, military personnel, and first responders don't clock out when the job gets hard. This kind of work demands strength, endurance, making decisions on a dime, and then being able to recover and do it all again tomorrow. That's exactly why REP Fitness teamed up with O2X Human Performance, the nation's leader in tactical athlete training. Together, we've got every angle of readiness covered, from the barbell to the dinner plate to the pillow.

The EAT SWEAT THRIVE™ ApproachAthletes train at an O2X event with REP equipment.

It's no shocker, but running on four hours of sleep and station coffee isn't going to cut it for jobs with such a high demand on physical and mental strength, and just being fit isn't enough to keep tactical athletes performing at their best. O2X built their EAT SWEAT THRIVE™ methodology around a whole person approach. Nutrition, conditioning, sleep, resilience, and stress management are all woven into one system that gets to the real meat of what helps people thrive in high stakes jobs. 

Where REP and Purist Nutrition Come In

O2X brings the programming and coaching, REP provides the cutting edge equipment that powers it. REP's racks, benches, dumbbells, and conditioning gear are already at work inside O2X training facilities, where tactical athletes can build the strength and conditioning that holds up during a 12-hour shift.

On the nutrition side, Purist Nutrition brings the "EAT" with clean, high-quality supplements. Purist's Whey Protein Isolate supports muscle recovery after training, while Creatine Plus and Purist® Hydration Powder support energy and performance when the demands don't let up.

The Partnership in Action

REP and O2X have already hosted hands on workshops for law enforcement professionals, covering everything from injury reduction strategies and fueling for performance to recovery, sleep, and fatigue management. This is the kind of training that keeps tactical athletes healthy and performing at their peak for the long haul — because they deserve it.
