Fully customized programming, hands-on coaching, and accountability every step of the way.

There is no such thing as a one-size-fits-all program. Each workout is tailor-made to your individual goals, skill level, readiness, background, and dedication to work.
Mactrain Personal Training and Player Development was created after my retirement from the NFL to continue my passion for fitness and helping others attain healthy lifestyles. It combines a wide variety of training modalities in a circuit and interval style — blending indoor and outdoor work with resistance, cardio, speed, agility, quickness, and football-based movements suitable for anyone. I train with creative movements, intense exercises, proprioceptive environments, and core-dominant workouts that move clients out of their comfort zones to strengthen total mind and body.
MacTrain LLC puts a real emphasis on increasing neuromuscular efficiency — aligning the nervous system (reaction time, coordination, balance) and the muscular system (muscles, joints, ligaments) to communicate more effectively for optimal movement. I specialize in working within each client's proper heart-rate zone: after testing your "Readiness to Train" (including max and resting heart rate), I calculate the right starting zone to assess, track, and maximize every session.
No matter how small or large your goals, I can help you achieve them in a safe, intense, and fun environment.
From the pro gridiron to the training floor — real athletes, real reps, real results.
There is no such thing as a one-size-fits-all program. Every workout is tailor-made to your goals, skill level, readiness, background, and dedication to work.
