Jan Bourg
Lifestyle and Movement Specialist

After retiring from a 30+ year career teaching and coaching (23 years at Coppell HS), I decided to start regularly strength training at Fit by Design. I wanted to get stronger and more fit so that I could enjoy my retirement days playing golf, pickle ball and playing with my grandkids. After a few months I noticed a drastic improvement in my overall fitness. My nagging hip pain i had for years was completely gone! In fact I was so impressed with my training with Kris I decided to become a personal trainer myself. I look forward to helping people of all ages achieve their fitness goals
