Get out of your
comfort zone

With Grant McCartney

We asked Ten Thousand athlete and 12-time American Ninja Warrior Grant McCartney to get out of his comfort zone by training with some of the most serious men in the country.

The Ultimate Amphibious Workout

Don Tran lives at the intersection of water and land. As a former Marine Raider and Water Survival Instructor, he’s endured brutal aquatic workouts and developed water training methods for other Marines that build up their water confidence, physiological performance, and mental toughness. Now, as a Co-Founder and Master Trainer at Deep End Fitness, Don designs, orchestrates and leads intense athletic training workouts for athletes ranging from MMA fighters to Olympic swimmers. After a near-drowning experience, though, Grant has never felt fully comfortable in the water. That’s exactly why we asked him to train with Don in a weighted swim and underwater workout – to get him outside his comfort zone with a workout that tested his ability to perform in an unfamiliar environment.
