Jace Ginestar

Personal Trainer

My name is Jace Ginestar and I am a Certified ACE Personal Trainer. Born and raised in Oregon and spend most of my time in the gym and outdoors. Getting fit and healthy physically, mentally and emotionally has been the main focus of my life. It’s not just about the time spent in the gym it’s what you do while you are at the gym that will translate into the things in life you enjoy doing. Have to be willing to do what others don‘t to get the results others won’t. Love to get started and start building towards your goals.

Gabby Herting

Personal Trainer


I am Gabby Herting, I am a NASM Certified personal trainer and former D2 javelin thrower. My passion for fitness started in high school and continues to grow the more I accomplish. I have extensive experience in strength training, sports performance, and weight loss. Finding a program that works for whatever your fitness goals are is what I am for.

When I’m not training myself or others, I am going on adventures with my husband and our two lab mixes.

I am here and ready to help you take the next step in your fitness journey, let’s do this!

Personal Trainer

Who am I? I graduated from high school locally and got a bachelor of communications at Oregon Tech. I have dedicated my life to a healthier lifestyle and I’m striving to provide the same opportunities for others. I started my fitness journey in May 2020 and I have successfully lost 50 pounds and kept it off the healthy way. Thank you National Fitness for the opportunity that you have provided me to help others. 

Who am I? My name is Clarence Gentry, and at one time I was 637 pounds. I had two strokes, diabetes and a failing liver, all caused by obesity. I was a shut in afraid of my own shadow. If I can lose 400 pounds and put my diabetes in remission, I can help you find High Expression of yourself!
