Just like my career, these testimonials span over 20 years!  They proudly reflect the experience my clients have had working with me both in-person and online.  


“Brian is very professional and succeeds in getting the desired results. He works within your personal timetable and builds you a custom program to achieve results for any level of performance. His ability to extend personal limits is amazing. I would recommend his services to anyone looking to attain short or long term results.”

— Ron Cambell, US Army Explosives Technician (EOD)


“Brian is not only a terrific motivator, he is EXTREMELY knowledgeable and professional in his approach to my personal training program. Brian is always available to answer my questions and to try new methods to help me achieve my goals. What’s really great about training with Brian, though, is his ability to push me to my limits, especially by introducing much needed variety into my fitness plan. I’m never bored and the best part is this: It’s working! I’m looking and feeling great! ”

“Occurs every Tuesday effective 2/4/2014 from 5:45 PM to 6:45 PM.”  That’s the recurring Outlook appointment I put in my calendar five years ago.  And it still stands (along with a recurring Thursday appointment).  That alone should tell you something.  After years of starting and stopping gym memberships and wasting money on them, and making excuses about being too tired to work out, it was time to make a commitment to lifelong fitness. 


An online search led me to Brian, who I subsequently learned had actually set up a fitness room at one our affiliate companies!  Brian is wonderful to work with (despite pushing me to do dreaded pushups).  He’s always upbeat, easy to talk to about many things (including non-exercise topics like what to cook, what car to buy, politics, movies, travel, you name it).  Seriously though, his workouts are thorough, exhausting and beneficial, not only for well-being but for training for other activities like skiing and golf.  Over the years, we’ve trained in person and using FaceTime and I love the flexibility as it means I don’t have to miss an appointment if I am out of town.  A+ all around, but as one of the other trainees said, just don’t try to nab my spot on the calendar!

“Brian is knowledgeable, entertaining (he can afford to be. I’m the one doing the exercises and sweating and sweating) and a great motivator. He took my baby boomer status as a real challenge, successfully working around my tennis elbow, rotator cuff problems, and slight (emphasis on “slight”) midriff bulge and devised an excellent exercise program for me. Brian listens, analyzes, and motivates. I’m delighted with the results. ”

— Joe McBrien, Broxville, NY

“Since starting training with Brian Day last year I am no longer the guy who gets sand kicked in his face. Instead he has managed to get me fit (against my best efforts to look for an easy way) and to do it in a way that is highly entertaining as well as highly efficient. Brian is a great motivator and training, and in addition to this, his knowledge is astonishing. As a research physician I know a fair bit about the body, but he knows far more when it comes to the anatomy and physiology of fitness. I know this as I often ask fairly abstract and technical questions. I have yet to find Brian lacking. This is clearly reflected in the exercises he puts you through, each session be customized to the needs, injuries, and overall plan. AND, in addition to getting you fit, he throws in free teaching on essential subjects (all things car related, movies, books, BMW’s, etc...). Alas he is wise to tricks for slacking off or using incorrect techniques to making things a little easier, but I guess if one wants to get fit in a healthy, injury free manner, that is not a bad thing. So, as long as you don’t try to steal my slot- I totally recommend trying a training session with Brian Day, you’ll stay on.”

— Jonnathan Picker MD PhD, Boston Children's Hospital


"Brian has been training my high school son Greg for the past year and a half and the results have been truly transformational! Simply said- there is no more knowledgeable or effective trainer around!"

-Neal Mackertich, Hopkinton, MA


“Brian has been able to adapt my training not only to my schedule, but also to the seasons. In winter time, when it is way to cold to train outdoors, Brian comes to my home with a colorful array of resistance bands and dumbbells. Using this equipment -plus my couch and other items of furniture!- Brian created an innovative and fun program that toned and strengthened core muscles. Now that summer is almost here, we’re into the outdoor phase with training that combines interval sprinting and resistance training, again using the bands. All in all, its a fabulous workout, either indoors or out!”

— Samantha McGarry, Framingham, MA


Having never cared for my body or fitness I finally realized I needed proper guidance and attention to change and fix a part of me I neglected. With no set goal on my mind Brian helped train me, educate me, and learn more about myself and my capabilities. The results have been seen in every day activities as well as long term fitness and diet. 

-Shawn, Upton, MA


“I began working with Brian Day in October of 2003 and have enjoyed every session. I was as physically unfit as one could be— Brian helped me to work wonders. Brian is very knowledgeable about fitness and psychology— he can talk me into a set when I’m not particularly “feeling it.” The difference In how I feel today and what I’m able to do still amazes me. Brian designs a program around his client’s needs, desired results, and fitness level. My program consists of training using free weights, a balance ball, my Reebok step, and bands. Brian is creative and flexible in coming up with new and different routines. No workout is ever the same. My weekly routine is producing the results that I desire. As a matter of fact, I’ve given my friends, associates, and loved ones in the area a session with Brian as a gift. Working with Fitness By Day has proven to be one of my better investments. ”

— Carolyn, Boston, MA


"As a mid40s software engineer leading a sedentary lifestyle with aching joint pains and possible trending towards carpal tunnel, I approached Brian with the request of not becoming a muscle-head, but the thought that I'd like to have a lifestyle that allows me to strengthen my core and flexibility in the long run. After a year+ of working with Brian Day, I'm incredibly happy with this progress and I can honestly say that my joints are ache free and I haven't had a problem with my arms / wrists in some time now."

-Todd, Hopkinton, MA


I'm not one of those people who wakes up in the morning and says "oh goodie, it's morning, I think I'll work out".  In fact I pretty much loath working out and can usually find another reason why I don't have time (cleaning the vegetable drawer of the refrigerator... dogs teeth need brushing ...) almost anything will do as an excuse.  That is until I started working out with Brian Day.  At first Brian would come to my home and for the past year he's been training me via FaceTime.  Both are fantastic.  Even when my motivation is at an all time low point, he manages to get a good 45 minutes work out of weight lifting, band work and cardio.  I started working with Brian 15 years ago when I was getting a bigger motorcycle.  I wanted to work on strength and balance. We achieved that and as the year's progressed it became even more important to keep active and strong.  Brian provides that base-line of weekly exercise that I can fill in around on my own.  I highly recommend Brian for those motivated for training (and especially those of you with erratic motivation).

-Sarah, Newton, MA


Working with Brian through many years, he helped me remain healthy and strong through injuries and even Cancer. If overall health is important, not just looking good, Brian is the one.
