    've known Karin for about 10 years.

    A highly motivating trainer, she will put you through a fantastic functional training session that will be challenging and designed to fit your fitness level.

    For me, Karin knows that I love being challenged. I was a hard core weightlifter for years. In my younger days, my leg presses where 860 lbs. Yes, I love a good challenge.

    Karin can have me sweating in no time flat. My heart rate will be reaching cardio level and I’m not killing myself doing hard core weightlifting anymore.

    Functional training is the best. Nowadays, I enjoy horseback riding and I need to be strong without any stiffness. Functional training will keep you fit without the bulky muscles.

    Karin is a qualified trainer. Her experience is superior to what I have seen in a larger gym. The training facility is clean, has plenty of parking spaces and is well located in West Hills.

    You should come and try it sometime!

    Okay, I have had to face the fact that I don't work out unless I have a trainer. The nice thing is that this gym has a small group rate per session that is very low, and yet Karin still personalizes the exercises for each of us. She calls if I don't show up, too. We do functional fitness, which means we do all sorts of different exercises with our body weight, or with weights, or TRX straps, or ropes, weighted balls, pulleys and weights, and other stuff. In a one hour session we do five different sets of six different  exercises quickly, with a minute rest between sets, plus warmup before and stretch afterwards. It's always changing, it's a good workout, and I feel so much more strong and flexible, and happy. Karin is also really sharp - she spotted I was dragging during some workouts, and asked me what I had been eating. After enough times I got it - eating too many sweets or cereal the day before caused it. Now I pay more attention to what I eat, and I feel better for it. I would have NEVER connected those dots.

    I received several private "personal trainer" sessions as a gift about 3 years ago and was referred to Karin, the owner of Function First Fitness. I was 48 years old at the time and in okay shape. I have always been athletic, but have a few physical issues that need to be considered as I exercise. Karin started me out with private sessions to really get to know my body's strengths and weaknesses. Her goal was to find a challenging work out that would not injure me. One might think this should be the goal of all personal trainers, but it definitely had not been my experience in the past.

    After my private sessions, I was moved into a class which was much more economical and enabled me to continue to exercise several times a week. Karin considers the physical challenges of each member of the class each week when creating our workout stations. We all use most of the equipment, just in different ways.

    I would recommend Function First Fitness to anyone looking for a small gym atmosphere with a knowledgeable and qualified trainer who charges affordable prices and truly cares about her clients.
