Background

Path to coaching

Started lifting at 19
Played football through high school, walked away after a torn ACL freshman year of college. Started lifting recreationally to recover. Got obsessed. Switched majors from finance to exercise science.
M.S. Exercise Science (Texas State, 2013)
Master’s focused on strength + conditioning + sports nutrition. Thesis on RPE-based programming. Worked under Dr. James Trinity, who shaped my whole approach.
D1 strength + conditioning coach (2013-2017)
Assistant strength coach at University of Texas, working with track + field, soccer, and tennis programs. 4 years. Learned how to coach 60+ athletes simultaneously without losing individualization.
Started Coach Reuben in 2017
Left D1 coaching to start an online coaching practice. Wanted depth over breadth — deep relationships with fewer athletes. Capped at 12 1:1 clients from day one.

Coaching philosophy

What I believe

Coaching > programming
Anyone can sell you a program. Coaching is the relationship — weekly conversations, video form review, real-time adjustments based on how you’re actually feeling. That’s where 80% of progress happens.
Form first, intensity second
I won’t add weight to a movement that’s technically broken. Months 1-3 of new client relationships are heavy on form work. Boring? Sometimes. Necessary? Always. Injuries set you back 3-6 months.
Sustainable > optimal
I don’t chase optimal. I chase sustainable. The program you’ll actually do for 12 months beats the ‘optimal’ program you’ll abandon in 4 weeks. We figure out what works for your life.
Truth-telling, not cheerleading
If your nutrition is the problem, I’ll tell you. If you’re overtraining, I’ll pull you back. If you need a deload, we deload. I’m here to coach, not to make you feel good about decisions that hurt your goals.
Periodization, not random workouts
Every block of training has a purpose. Volume blocks → intensity blocks → peak blocks → deload. We don’t do random workouts. Programming follows a plan that maps to your specific goals.
Strength is the foundation
Whether the goal is body comp, athletic performance, or longevity — strength is the foundation. Most clients spend significant time getting stronger before adding sport-specific or aesthetic goals. Strong bodies do everything better.
Credentials

Education + certifications

M.S. Exercise Science · Texas State University (2013)
Strength + conditioning concentration. Thesis: RPE-based programming for collegiate strength athletes. Advisor: Dr. James Trinity, NSCA Coach of the Year 2011.
B.S. Kinesiology · UT Austin (2011)
Switched from finance major sophomore year. Magna cum laude. Worked at the UT athletic performance center as undergrad assistant.
NSCA-CSCS (active since 2012)
Certified Strength + Conditioning Specialist. The gold standard for strength + conditioning. Renewed every 3 years with 60+ continuing ed credits per cycle.
Precision Nutrition L2 (2018)
Master nutrition coaching certification. The framework I use for macro coaching + nutrition guidance. PN-L2 is rare among coaches.
PROnatal Fitness Cert (2019)
Pre + post-natal fitness certification. Important for working with pregnant + postpartum clients. ~15% of my client base is pre/post-natal.
Continuing education
I attend 2-3 conferences per year (NSCA National, NSCA Coaches, Stronger by Science Live). Read 5-10 strength + conditioning research papers per week. The field evolves; my coaching evolves.
Why I cap at 12 clients

The math + the values

1:1 clients require 4-5 hours/week
Weekly 30-min check-in + form review (1-2 hours weekly) + program design (1-2 hours weekly) + texts + emails (~1 hour weekly). 12 clients × 4 hours = 48 hours. That’s a full week without burnout.
Group + self-paced are scalable
Group coaching scales because the programming is shared. Self-paced programs scale infinitely because there’s no coaching involved. Both let me serve more athletes without diluting 1:1 quality.
I make less by capping
Most online coaches scale to 50-100+ 1:1 clients (and use junior coaches behind the scenes). I’d make 4x more. But the quality drops, and that’s not the business I want to run.
Full-stack solo coach by choice
I write every program. I review every form video. I run every check-in. One assistant handles operations + community. The coaching itself is 100% me. That’s the product I’m selling.
Waitlist is real
Average waitlist is 4-8 weeks. Sometimes 0, sometimes 12. I open new spots when existing clients hit their goals + transition to maintenance. Waitlist position confirmed during your free assessment call.
I won't expand
Many coaches ask why I don’t hire junior coaches + scale. The answer: that breaks the model. I’m a coach, not a coaching CEO. The 12-cap is permanent.

About-the-coach questions

What clients want to know

  • I powerlift recreationally. Compete in master’s class once or twice a year. Current PRs at 39 (185 lb bodyweight): 525 squat, 365 bench, 615 deadlift. I keep competing because it keeps me honest about programming.
