Kara Mayock
Kara MayockPersonal Trainer
Kara is originally from the Massachusetts/Connecticut area. She moved her family to Pine, Colorado in 1997.  As a professional working mom of three children living in the mountains, exercise was a key element to maintaining a healthy work/life balance. 
She immediately took advantage of mountain sports, including climbing 14ers and regularly skiing/boarding with her children.

Kara has always been an exercise enthusiast. However, after experiencing the Personal Training difference as a client of Core Progress, she decided to put her passion for exercise and nutrition to good use and received her Certification as a Personal Trainer through the American Council on Exercise (ACE) in 2016.

Her philosophy on maintaining a healthy lifestyle is based on creating a realistic balance between nutrition and exercise. She knows firsthand that you can achieve results and maintain a healthy lifestyle without sacrificing all of your free time and fun.

Josh Van Tine
Josh Van TinePersonal Trainer
Josh moved to Broomfield, where he grew up, when he was nine. He went to college at the University of Northern Colorado where he wrestled while receiving a degree in Sports and Exercise Science.
During his Junior year, Josh did his internship at a physical therapy clinic which gave him valuable experience in injury prevention. After his internship, he went down the path of personal training and has observed at the CU Sports Medicine and Performance Center.

After college Josh decided to become certified through the National Strength and Conditioning Association as a Certified Strength and Conditioning Specialist in order to help others improve and achieve their goals. Even though he wrestled through college and had a strength coach, when he was done Josh struggled to work out on his own. Knowing he was not the only one, this is what ultimately finalized his decision to pursue personal training. Josh has a background in sports training and strength training for fat loss.

In his spare time, Josh likes playing volleyball and wrestling, but still enjoys watching cartoons.

Lance Henkel
Lance HenkelPersonal Trainer
Certified through the American Council on Exercise (ACE), my emphasis is on improving human performance with clients ranging from recreational to competitive athletes, youth to adult, fitness newcomers and long time enthusiasts.
A passion for fitness and investing in others led me to personal training and has been very rewarding. I’ve personally spent countless hours training and preparing to compete successfully in many areas such as NCAA Division 1 football (Iowa State University), numerous triathlons, cross-training and adventure competitions. I have had many people help me along my way and now I enjoy sharing my knowledge and experience with others to help them reach their wellness, fitness and athletic goals.

My motto is, “Training for the athlete inside everyBODY!”
