WHAT PEOPLE SAY

"Over my years of a gym membership, I have tried numerous trainers but I didn't last with any of them until I found Mitzi. I have never enjoyed weight work even though I knew it should be part of my workouts. Mitzi has helped me enjoy and even look forward to my weight work thanks to her upbeat personality, encouragement, and willingness to challenge me. Despite her full schedule, Mitzi doesn't take a cookie-cutter approach. She treats me as an individual and modifies my workouts based on my goals and my physical limitations. In my time working with Mitzi and following her workouts, I have seen my BMI decrease and my muscle mass increase, which is exactly what I was hoping to achieve."

"Over a period of 15 years, I have worked with multiple trainers at four Dallas gyms - Baylor, Life Time Fitness, LA Fitness and Texas Family Fitness.  Mitzi Collinsworth is the best trainer I have encountered and by far the most pleasant to work with.  A competitive gymnast in her youth and with 27 years of experience as a personal trainer, she brings to the table an in-depth knowledge of physiology and nutrition, and an ability to optimize physical wellness through carefully calibrated personalized training.  She is particularly good at both avoiding injury and helping clients address it when it occurs elsewhere.  She is attentive, focused and unfailingly upbeat.  I have yet to find her equal anywhere else.  In short, I highly recommend!"

"I first met Mitzi about 5 months ago, at which point I was diagnosed with degenerative disc disease.  For me, it was characterized by lower back pain that worsened after I had my first child.  Training with Mitzi has drastically improved my quality of life!  She has helped me regain my strength and energy.  She has tailored for me a sustainable exercise regimen which also minimizes the risk of injury to my already compromised lower back.  She really listened to me about my goals and concerns. I feel like my old self again. I would recommend Mitzi to anyone!"
