Coach Alex — Personal Trainer in Hesperia, CA
Alex Hernandez leads personal training, youth sports performance, All The Reps strength classes, and online fitness and nutrition coaching at ATG Fitness.
Coaching approach
Training with purpose
Alex coaches with one conviction: fitness is worship when it points back to the Giver. Across 15 years of coaching, he has worked in individual, group, youth, and remote settings. At ATG Fitness, that experience connects four programs under a common approach—clear instruction, appropriate progressions, accountability, and service.
Young athletes work on broad athletic foundations such as speed, agility, jumping, strength, and confidence. Adults can choose one-on-one personal training or All The Reps, a coach-led strength and conditioning class built around progressive training blocks. Clients who train elsewhere can work with Alex through online programming and nutrition support.
Not every client needs the same format. Review the programs below, then use the live booking system or contact ATG Fitness if you want help choosing a starting point.
