about us

We Live To Help Train You

CrossFit is a functional fitness training program that builds strength and conditioning through varied and challenging workouts.  Functional fitness is essential to maintain quality of life. At any age, you should be able to squat, lift something above your head, and get yourself up off the floor without assistance.  Each day our workouts will develop a different part of your functional fitness, not specializing in one particular thing, but rather with the goal of building a body that’s capable of practically anything and everything. At Ground Up, you will never have to look around wondering how to use machines, how many sets you should do, or continue to do the same long circuit routine day after day. 

Constantly varied: Each day there is a prescribed Workout of the Day. You never get bored because each day the workout is different. The best part about it is everything is scalable for every level of fitness. Our expert coaches tailor your workout based on what you need or are capable of. As you become more fit, they continue to modify and advance. 

What makes us different? Our Fitness works. All fitness is good, don’t get us wrong, but if you don’t change as a result of a fitness routine, is it really effective? At Ground Up you will always feel welcome, always feel support, and always feel like you are becoming the best version of you.

We believe in fitness at all levels and ensure you have the resources to be successful at any fitness level. At Ground Up we care about HOW you are moving, not the amount of weight you move. Your lon-term success with functional movement is our #1 priority.

 We are the only CrossFit Kids Program in Hastings and offering regular CrossFit Preschool, Kids and Teens classes and the only gym with CROSSFIT CERTIFIED KIDS TRAINERS. We believe in fitness at all ages and have dedicated the resources to invest in your children year around!

I love helping others achieve their fitness and nutrition goals. Since Nutrition is the building block of fitness, I enjoy helping others live their best life and learn how to eat to not only decrease body fat and gain muscle, but to eat for everyday living.  As a CrossFitter who is 50, I am committed to the older athlete, teaching adults in the middle of their life how to move safely to ensure longevity. In my free time, I enjoy walking my dogs, spending time with family and friends, gardening, and being outside living life.
