Personal Trainer

Hi, I’m Tisha! I’m an ACE Certified personal trainer and have been a member of NFRC for going on 6 ears now! I found my passion for fitness here on the weight floor, as I was never very sports-oriented in school. I believe exercise and good clean nutrition are extremely important to not only your overall physical health, but your mental health too! That’s why I started Uplift Fitness, to strengthen your body AND mind. Fitness isn’t just about looking good after all, it’s mainly about feeling good.


Personal Trainer

Education: ACSM certified PT, A.C.E. certified PT, Associates in Para medicine, minor in Fire Science, extensive studies in Anatomy and Physiology.

Focus: My focus is you! I want to know you on a personal level to better help achieve your goals and aspirations. Beginning with an consultation, together we will go over you in a whole; your lifestyle, your eating habits, sleep schedule, gym knowledge and your fitness priorities so I can custom tailor a regimen inside and outside the gym. Whether it be weight loss, muscle gain, contest prep, or overall improved health together we can get there! My focus will be to educate you about various machines/equipment, workout regimens and splits, meal prep and proper nutrition and proper form/biomechanics and safety. With my focus and your determination success is on the horizon to make you better everyday in improving your health , longevity and lifestyle and all the while looking good while doing it!

About me: Born March 1980, native of Utah, moved to Oregon around 6 years of age. Started my journey in health and exercise at age 14 and  was addicted, for 26 years now I have never stopped learning, adapting and trying new things with health and wellness. Attended Southern Oregon University in a wrestling scholarship where I studied business and sports medicine, from there I transferred to Rogue community College to obtain a degree in Para medicine. I am currently an NPC competitor and routinely compete in bodybuilding shows amateurly with aspirations of achieving pro status. In  2016 I decided to start a personal training business (STEEL THERAPY) to extend my knowledge of safety, equipment, proper technique and form of weight lifting, biomechanics, nutrition, meal prep and supplement consultation. Health and well being is a lifestyle! Are you ready to join me??
