Samantha Demers

Johnston, RI 02919

Throughout my formative years, I was overweight, even though I had always been very active and athletically inclined, playing sports across all four seasons. At some point, I became self-conscious of my weight and decided to do something about it. I began to research nutrition, made lifestyle choices, and trained myself to ultimately improve my weight by fifty plus pounds.

Training in a realistic self-defense school (Kuntao Jiu-Jitsu), gave me the opportunity to instruct in the youth program, which opened my eyes to attending graduate school for teaching. During my post graduate studies, I realized my true desire was to combine fitness, nutrition, teaching, and motivation into a career (isn’t that what we all try to achieve?). I am having the time of my life, living my dream and helping my clients reach their goals!

I am committed to bringing affordable, enjoyable physical challenges to my clients. Instructing students in self-defense has given me experience in paying attention to clients’ bodies and forms. Each workout is catered to the particular client and is based on their needs.

I like to keep myself sharp and I am always looking for new workouts, which helps me to improve the exercise plans for my clients. As my passion for fitness grew, I started racing in triathlons four years ago, which has opened a new set of physical challenges that will prove beneficial to my clientele.

    Samantha motivates you while training so that you quickly see your body growing stronger, healthier and more resilient. She corrects your form using her winning smile so that you don't mind working harder. Whether you are punching, kicking or swimming you feel more energized, alert and vibrant during and after your workouts. In the end, if you've accomplished a new skill or improved on one, you feel better about yourself and you can see yourself attaining other personal goals easily.

    I have been training with Samantha since Jan ( three months) and have already seen a difference in my body, mood and energy level.

    She is patient and persistent ( even when I am not) and has a deep understanding of her client's psychology as well as their physiology. Both likeable and professional, she has never been late and mixes up the routine before I get a chance to get bored.

    Hiring Samantha as my trainer is one of the best things that I have ever done for myself. I would recommend her highly and with great enthusiasm to anyone who is invested in losing weight and getting fit.

    when I first went to samanthas place I had no idea what to expect.being a way out of shape 42 year old man all I knew was I needed some help to change my habits and to loose some wt I had accumulated from being sedimentary for years.
    I arrived and was met bye a very polite,positive and non judgemental person who instantly made me comfortable
    being there.
    she did a full measurement,wt and fitness evaluation,
    we spoke about goals,and setup a two to three day a week training program.
    samantha's training was a mixture of cardio,strength,alot of core training,and even some boxing/martial arts to keep it interesting.our sessions where always 1-1 no people watching no phone calls 100% commitment to the session.
    every day of training was something different and challenging.after a few weeks she will have you gasping for breath for 50 minutes and enjoying every second of it.
    At the end of 6 weeks with samantha I had dropped some 25 pounds and and had a shape I hadent seen in 20 years.
    her supportive attitude
    her skill
    and commitment to your health
    you won't find a better trainer anywhere.
