Jamıe ıs a great life fitness coach. She listens to her…read moreclients as well as finds the very best approach to achieving the goals. Finding the right person is critical and I am grateful I found her.

Jamie D is a fantastic gem of a health coach! A close friend of mine introduced me to her a few…read moreyears ago and I'm so grateful for that! She is funny, intelligent, and a subject matter expert in this field of healthy living. She also practices what she preaches: she does daily exercises, morning runs, and strength training so she can vouch what she does for herself and her clients really works. As for myself, I've struggled with my weight post-pregnancies, with several permanent injuries, bad knees, and being my mid-forties. I really wanted a patient trainer that will keep me motivated, keep me in check to be mindful, aware and accountable for my life style choices, YET still not be a mean drill sergeant that I want to hide from! Jamie is the perfect blend of humor, honesty, positivity, humility, and deep well of knowledge and experience. Bonus: she also is a SME in real estate! I find her 1 hour sessions to be highly effective, efficient and fun workouts. Jamie has an amazing vibrant personality, motivating me especially when the set starts gets challenging, giving me clear, concise tips on getting my form right and pretty soon the session flies by. Two days later, the inevitable muscle soreness comes in to prove the workout has made me stronger and healthier! I'm still a work in progress as I have an end boss goal to drop from 200 lbs to my weight pre-pregnancy days. My initial goal is hit a healthier BMI by being 10% less than my start weight, which will be my first milestone. The coaching sessions tremendously help me mentally and physically since we laugh and talk about life's crazy adventures as I lift, squat, lunge, push, pull and pump iron. It's a full-body workout that has short little rests in between and she'll pace it to make it enough of a challenge each time. Checking your form, adding more resistance, counting it down, easing it if needed and most importantly, encouraging you as sweat is rolling down your back as you plank down. I put a few pictures of me and my family below to show that no matter what age, shape or stage you are in life, you can always be an inspiration and role model to your family and loved ones. I just love feeling stronger and knowing I'm adding years to my life to be there for the ones I care about. In conclusion, I highly recommend Jamie for her health coaching services and as you get to know her, it will be revealed how very gifted and talented she is that your coaching sessions will fly by and you will feel great afterwards!

How convenient it was to have the best personal trainer in the area come to my home to put me…read morethrough a personalized boot camp class! (Yes, Theo, don't start blushing yet, here it comes...) I work from home and have young children so Theo made it possible for me to keep my schedule and have an eye on my kids at the same time. He is very professional and you can tell he's a therapist too because we were able to address my motivation during times when I didn't want to exercise. He was able to switch up the exercises to keep me interested and adapting. We did Boot Camps, Circuit training, boxing (great mental release too!), and even did a few of our sessions in the pool because of his background teaching swimming lessons. Unfortunately I no longer live in the area but I would recommend him to anybody looking for a unique fitness experience and is well worth his price. I also heard he works as a senior fitness health specialist and I'm going to have him start working with my mother who is 65 years old when she gets out of physical therapy. Okay, now I'm babbling but I think it's pretty clear what I think of him :) Theo, i'll be contacting you when I come back through the area for another session in the park!

I was in town for the weekend visiting family and had the opportunity to check out the Renaissance…read moreClub Sport in Walnut Creek to exercise, which is a beautiful facility. Occasionally when I'm on the road I look for someone to assist me in my my exercise program and came across Theos personal training yelp page. He was able to come to my hotel and Gym for two personalized workouts during the time I was in town. I have a personal trainer back home, and it was great to have Theos psychotherapeutic influence in our training. It felt like a combination of therapy and exercise. I would imagine that he's a great personal trainer to have if you live in the Lafayette or Walnut Creek area and would absolutely recommend him to people who are in town visiting and looking for a trainer. I will definitely have a few more sessions next time I'm in town! Thanks Theo!

This review is long overdue. I started my fitness journey 6 years ago and I've been in and out of…read morevarious gyms depending on where I live and where I work. I have to say out of all the gyms I've been to: FBBC, UFC, Planet Fitness, The Camp, and many other local family owned gyms, Concord fitness boot camp aka Fit Body Boot Camp concord has been the absolute best! I lost weight but the change was not just in appearance. I actually felt stronger and could notice the difference in my strength. My energy and endurance was like my teen days. The crazy part is appearance wise this gym has been the least impressive. But Virgil makes the small space functional and you really don't need much more than this. When I showed up for my first trial the location made me hesitant. Virgil's customer service was great and he made me feel welcomed. The other members were friendly and there were all ages and body types. I stayed and loved it. Everyone was extremely helpful and motivating. They all push you to finish your reps, to keep moving and not quit, and if you struggle they make you feel okay with modifying while teaching you ways to work on it until you can one day do what you're struggling with. It was hard but it seemed like within days my body learned how to handle doing sit ups and push ups. Another major part is nutrition. Virgil helped me with a shopping list and meal ideas. He is respectful but also doesn't sugar coat. With each weigh in he reminded me what I needed to do to stay on track. I also learned how to count calories. If I still lived in the area I would see about joining again. If I didn't give it 5 stars it is solely because of the cost. When I went it cost around by $300/month. Is it worth it? Yes. Is it affordable and feasible? No. I could not keep up going there as it was too much for my budget. Pictures for comparison of cheeks and chin when I first started in March to September

Came here for my first Bootcamp class via ClassPass. When I arrived, I wasn't sure if the place was…read moreactually open for business because it was boarded up on the windows. With reassurance from the owner (whose phone number was on Google), it was indeed open for business, I was excited to get moving for my Friday workout. I was introduced to the owner and other people who showed up for the class and I could tell they were regulars. The place looked pretty legit as you know I love legit gyms :-) I was asked to disinfect the bottom of my shoes as street shoes aren't allowed on the floor, since we laid on them for floor workouts. That made me feel better because I ain't tryna rest my head on a floor where people before me don't know where to walk sometimes and you don't know where they come from ahem, SF CITY STREETS!!! This was my first Bootcamp class in a long while so I was pretty thankful that Virgil (owner and trainer) allowed me to modify my workouts. It was a damn good sweat and I had great energy the rest of the day.
