About Krystin

My name is Krystin Weiss, I am the owner and operator of Impact Fitness & Nutrition and an engineer of the human body!   My purpose in life, that brings me the most joy, is to help others become healthier versions of themselves through fitness and nutrition.  My motivation comes from losing my parents far too young because of the unhealthy choices they made. They have become my inspiration, my reason, and my 'why'.  I don't want others to experience what I personally went through, so I'm on a mission.  My passion, from my own experience, is delivered into every single client I coach and train. 


My specialty and passion is working with young to older adult women.  I have assisted numerous clients with weight loss, corrective exercise, strength, mobility, and balance, just to name a few.  My programs are all customized based on the client's needs.

I have been in the fitness and nutrition industry for over 20 years. I am a nutrition specialist and hold an Associates Degree in Dietetics and am registered with the Commission on Dietetic Registration, the credentialing agency for the Academy of Nutrition and Dietetics. I am a certified personal trainer through the American Council on Exercise (ACE). I am also certified as a group fitness instructor for Les Mills in BodyPump and RPM.  I love, love, love to learn and continue my education by staying abreast of the latest fitness and nutrition trends.  I am a certified Weight Management Specialist through ACE and am certified in exercise nutrition through Precision Nutrition - PN Level 1.  I am also currently pursuing certification as an orthopedic exercise specialist. Extensive experience in nutrition coaching for the healthy population, personal training clients in 1:1 and small group settings, and teaching numerous group fitness classes has enabled me to transform lives, for the better.  

In 2016, I began my business, Impact Fitness & Nutrition, where I take personal training to you.  I'm a mobile gym and will take all the necessary equipment for each session to you, in the comfort of your own home.   It's convenient, private, highly personalized, saves you time, and is very affordable.


I look forward to walking alongside you through your health journey to a healthier better tomorrow.
