Fred Brandt: Owner – Personal Trainer – Group Instructor

My name is Fred Brandt and I am the founder and owner of Fusion Fitness. I have a lifelong passion of living and promoting health and fitness within the community. In 2010 I decided to dedicate myself full time to providing health and fitness training and guidance to the people I serve. I am certified as a personal trainer, health and wellness coach, corrective exercise specialist, boxing instructor, TRX instructor and have a lot of experience in the gym. I have been boxing for many years and enjoy teaching others the skill. I am no stranger to injury either. I underwent neck fusion in 2010 and know what it is like to work around an injury and get yourself back into shape. I have worked with a broad spectrum of clients from the young, elderly, elite athlete to someone who has never picked up a dumbbell before. I use my years of experience and knowledge base to develop a health and fitness plan that is best for you.

Eric Nickerson: Personal Trainer / Group Instructor / Facilities Manager

My name is Eric Nickerson and I’m 60 years young  retired Sacramento county employee. I spent 36 years with the county and the last 10 behind a desk. I gained 50 lb and weight an unhealthy 250 lb. I was just a grandpa chasing granddaughters to sporting events with never a thought of exercise. Retirement was setting in and all my honeydew lists were complete, I knew it was time to make some healthy life changes. My daughter introduced me to Fusion Fitness in February 2016. My fitness journey began to change as I was introduced to to instructor led workouts and then turned my focus on proper meal planning for my goals. I have trained hard and have learned a lot from the Fusion trainers for the last 2 years. I have been able to get my body fat as low as 8 % where I then started my rebuilding. I have recently received my Personal Training Certificate, and with the continued training and mentorship from the staff at fusion Fitness I plan on working hard to be a great Personal Trainer.
