Not a gimmick, and not a crash program. The 21-Day Challenge is a concentrated block of real, progressive training — the kind of momentum that’s hard to build on your own, delivered by a certified trainer in your home.
Designed by Nathaniel Oliver, founder of Type A Training, it’s built to do one thing well: get you moving, consistent, and genuinely stronger in three weeks — and set you up to keep going.
Built on five essential components
Real results don’t come from workouts alone. They come from getting all five of these right — which is exactly how this program is designed.
Clear Goals
Specific targets, set from day one, so every session has a purpose.
Personalized Workouts
Built around your body, your level, and your goals — never generic.
Nutrition Guidance
Practical, sustainable guidance to fuel the work you’re putting in.
Progress Tracking
We measure what matters, so you can see the change as it happens.
Ongoing Support
Daily accountability and a trainer in your corner the whole way.
“To reach your goals, you need all five. If one is missing, your results are limited. This program is built so none of them ever are.”— Nathaniel W. Oliver, Founder

“I am that person who dislikes gyms, group classes and in general, working out. Insert Type A Training. I enjoy the intense workouts in a consolidated amount of time. Appreciate Nathaniel’s ability to come to my apartment and fit in our sessions around my work schedule. His personality is firm, yet supportive – the ideal personal trainer in my book. 8 weeks in and I’m down a jeans size. Results matter to me and I’m getting them with Type A Training.”— A S., Yelp
