Jonathon Spencer of Dallas, Texas, says his first interest in the fitness industry came from growing up in an athletic family. Being raised to believe in health, sports, and all around physical fitness made such an impact on Spencer that he has turned it into a successful career. “I just get a kick out of helping others transform into a well-rounded fit person. It’s my calling.” Spencer says, “and my knowledge, persistence, hard work, and dedication to fitness is what got me where I am today.”
Spencer graduated from Oklahoma State University with a degree in Exercise Physiology, and also holds a degree in Biomechanics. He is dual certified from the Cooper Institute as both a Physical Fitness Specialist and a Nutritional Specialist.Spencer’s passion for Rockstar Fitness is evident in his discussion about the camps, “I know that Rockstar will benefit anyone because our formula will keep you in your target heart rate zone, resulting in the most efficient use of your workout, and our workout environment is not like any typical camp because we devise our program to fit different levels of fitness. It works for everyone!” “No other camp can come close. Shoot…we have live DJ’s spinning for our camps. Enough said.”
Jonathan Guajardo is not only the newest member of the RockStar Staff, but he is also a living example of the program itself! In just a year he lost over 60 pounds, decreased his body fat percentage and developed muscle. “I’m a walking result that with RockStar Fitness, a nutritional balanced diet and a lot of dedication, you can get to where you want to be physically! RockStar isn’t just about a group work out. It’s about maintaining your health, pushing yourself to the next level in fitness, diet, & life. It’s about creating a healthy lifestyle.…the RockStar lifestyle!”.
At age 18, Jonathan’s fitness working experience began as Youth Camp Counselor at the Frisco YMCA and later as Teen Camp & Fitness Programs Director in Plano. “Learning how to influence kids with good habits has helped me in teaching healthy habits to our clients.” His gym experience also includes LA Fitness, Gold’s Gym, & currently with Trophy Fitness/Downtown. “The gym environment and all the knowledge about health one can sponge up and let people know about is why I love doing what I do.”
Besides training, Jonathan is the Consultation Specialist of Camps, charting measurements, body fat & BMI. “To me, RockStar is the very best way to get that healthy lifestyle I’ve come to love. With the live DJ, urban plush environment, high intensity & great trainers, it’s the Best Camp out there! ON ALL LEVELS!
