If it doesn’t Challenge you, it doesn’t Change you.

Simply put, Vitality Athletics’s mission is to help you, “Change Your Life With Us.” After spending time in our facility and with our team, we want our members to walk out of our doors after a workout and feel like they are better versions of themselves. It isn’t the scientific sum of calories, workouts and weight that keeps our members returning. It is not the cutting edge equipment and technology. It is the people that count. Our team cares about guiding and encouraging each and every member to obtain the goals they seek for themselves. Our members’ goals are specific, and if we can assist in that journey to realizing their aspirations, then we have truly helped them change their lives.

Road Map

You have the goals and the motivation. We have the knowledge and the resources. Let us help you plan your trip for your new journey.


Data is the secret ingredient to successful training. We track every number that you lift within our walls, making you become better, faster.


We offer the largest FREE accountability group on the planet. We workout and play together often. Workouts aren’t bad when you’re making new friends.


The best nutrition education hands down. Whether your goal is to lose 100 pounds of fat or put on 30 pounds of muscle. Our nutrition guidance guarantees results.

I found this gym after trying for a long time to work out on my own, with little success. I think the two biggest draws... to coming to this gym is the camaraderie amongst the clients and the versatility of Tyler and his team's workouts! Experience with crossfit, and exercise in general, is not necessary prior to starting. A good attitude and a motivation for change is all that Tyler needs to get you to your fitness goals. He and his instructors work with you on becoming comfortable, emphasize good form to ensure longevity, and hit multiple important muscle groups with each workout. The fee for membership (which is reasonable compared to other crossfit gyms) is WELL worth it as an investment in your health and happiness!read more

After attending Vitality Athletics and working out with the “Boomfit” class my cholesterol has dropped from 214 to... 195 in a year. I am stronger and more flexible. Tyler and his trainers are positive, knowledgeable and inspiring. They encourage you to constantly improve. Also, I’m working out with a group of wonderful people who are genuinely concerned with each other’s health and welfare. A true more

I contacted Tyler (a college teammate of mine) when I needed to lose some (a lot) extra weight. I lost over 20 lbs. in... two months and couldn’t be happier. I still have a handful to go and I am confident that his guidance will see me to my ultimate goal. This is the place to go for self improvement; the staff is knowledgeable and genuinely interested in helping people achieve their goals. PLEASE see Vitality Athletics Ephrata for serious more
