About David

My name is David Zemanek, I am a Personal Trainer at Proactive Lifestyle Fitness in Katy, TX. With multiple certifications as a NASM Certified Personal Trainer, NSCA Certified Personal Trainer, EXOS Performance Specialist, and NASM Corrective Exercise Specialist, my broad background enables me to effectively coach clients from every walk of life. I abide by the philosophy of a healthy lifestyle being a journey rather than a destination, and my enthusiasm for my clients’ success shows in the way I educate, motivate, and inspire them toward their goals. I also work to instill my passion and knowledge into the upcoming generation of personal trainers through the NASM CPT coursework I teach as a trainer to trainers.

My experience with instructor David Zemanek was absolutely worth my time and investment. With his knowledge, skill and experience, David demonstrated each session with great enthusiasm. He planned every class literature and floor session with dedication and encouraged student(s) to participate in discussion and welcomed opinions and/or questions. Every session was full of pertinent information and I would leave, gaining a broader knowledge within the fitness/health industry. David is a ‘beast’ full of energy and positive attitude!
