NEW CLIENTS – Take Advantage of our Intro Package, 2-Weeks of Unlimited Training

I highly recommend Jacob from Fenix Fitness Training!

I have been working out with him 2x a week for the last year and a half! As a busy mom of 4 kids, my schedule always seems to change and Jacob is beyond flexible with finding a time that works with you each week.

He develops a plan with you to best meet your physical and nutritional goals. He is very good at meeting you where you are and showing you where you can go! He keeps in touch between workouts to make sure you are staying on track and keeps you encouraged. He is very knowledgeable when it comes to all things training and nutrition related. He sees the potential in you even when you can’t see it yourself.

Not only has he helped me change my diet, but I have become the strongest I have ever been! I am hitting new PRs weekly! If you are looking for a personal trainer, I cannot recommend Jacob enough!

Workouts in Privacy and Comfort

Gyms have all types of fancy equipment, and spaces for various activities – they’re also packed with people.

Most people don’t need all the fancy equipment to get fit and healthy.

What you need is a proven set of exercises, a plan for how to perform them, and knowledge about what to eat in addition to your workouts.

Our personal trainers can train you wherever you want because they don’t require any equipment or large spaces. They can help you get fit and healthy without the gym.

“Working with Jacob to accomplish my goals is one of the best decisions that I have ever made. His constant encouragement and advice helped me to surpass my original goal and inspired me to keep setting new ones. The hard work and discipline that he instilled in me showed me that I really could do whatever I set my mind to.”
