I have been going to MB for 2 years now and this gym has made me into a completely different person. I go in there super stressed and sad sometimes and I come out of the place super happy. The people in mb make me the best I can possibly be and I really want to thank Matt and Steve for always being there when I need support. I look up to these coaches so much and I couldn’t have asked for a better place. I have not only excelled in my sport, but I have became a happier person due to the environment that MB creates. I highly recommend for any athlete that wants to be the best they possibly can at their sport and be their true selves.

I had the opportunity to work with Matt for several years, first as my high school soccer coach, and then training with him at MB Performance Institute. Matt played a huge role in preparing me for the jump from high school to collegiate soccer. His training helped develop my strength, conditioning, and overall athleticism, while also continuing to build my technical ability on the field. Due to his coaching and mentorship, I came into college ready to compete at a high level. For any athlete serious about improving and taking their game to the next level, MB is the real deal!!

Where to begin reviewing one of the better overall fitness institutions in the South Shore area. When I began to MB Sports roughly 2.5 years ago, I was a bit lost in my fitness journey. I was burnt out, tired of the typical routine. Walking in to a gym with no plan or goals, lifting, and leaving. Never seeing results. A plateau was reached. I was scared to change up my routine, but I knew I needed to do something. I found MB Sports and gave it a chance. Having come from "Planet Fitness" type spaces, a local gym run by former and highly successful college athletes and knowledgeable trainers/coaches was needless to say intimidating. But the kindness and attention to detail that both Matt and Steve showed me upon entering was phenomenal. They took the time to get to know me. My strengths, my weaknesses, and most importantly what goals I had. No judgement was made about what I could or could not do. Their only interest was helping me improve. In addition to the many student athlete offerings they have, the adult fitness program is a thoughtfully detailed and consists of functional strength and conditioning, while also an emphasis on cardiovascular health. Phases and workout plans are built with attention to detail. I'm now part of a fantastic group of adults who meet every single morning at 6am to workout. To encourage each other and to keep pushing, even when it gets hard. There is genuine community feel here. Over the past couple years, I've competed in many races including my first triathlon last Fall of 2025. Two and half years ago, I never would have imagined doing such a race. But because I had built the confidence and improved both physically and mentally, I knew I needed to challenge myself to do something outside the comfort zone. I had no hesitation on who I wanted to help me plan out my training. I would not be where I am at today without Matt and Steve's guidance. To any adult looking to improve both physically and mentally, to change up their mundane routine, to push yourself further and achieve milestones you would not think you could do, I can only recommend MB Performance Institute. "If it doesn't challenge you, it doesn't change you"

I can not say enough great things about this gym! My daughter has struggled with her club this year, a lot of demands, negativity and yelling. I heard about MB Performance and their mission stood out to me so she gave it a try. I noticed after 1 week her mindset shifting and not as much complaining when having to go to club practice. She still deals with the negativity from club but now she has an amazing trainer and place to go workout that is lifting her up every time she steps through the door! They really care about the whole athlete and not just the wins and it makes a huge difference. She's still being coached, held accountable and challenged but all from a place of wanting to see her grow and encouragement! Thank you MB Performance!

MB is Cain’s “home away from home” ("home" being Daniel Gracie Academy). Matt and Steve over the last year have welcomed him and crafted programs to address his unique training needs for grappling/Jiu Jitsu and mixed martial arts. It is generally advisable that fathers not coach their sons. MB Performance allows me to rely on their experience and expertise to essentially “outsource” the responsibility of designing strength and conditioning programs for Cain. Training at MB is also a perfect compliment to his homeschool curriculum. MB is not a meathead gym that’s going to try to get your youth athlete yoked-up like a bodybuilder or risk injury by not evaluating their ability. MB’s goal is to not just train them for their specific sport. They teach them to be ATHLETIC, with emphasis on functional strength, agility & mobility. MB also incorporates joint preservation and active recovery. Your child will not likely be exposed to this type of approach until they reach the collegiate level and 100% won’t get this with their buddies/peers goofing around at Planet Fitness (furthermore I am not aware of many middle schools with weight rooms). MB offers the perfect mix of supervision and independence, critical for youth athletes. Gains and progress are continuously monitored and assessed, providing valuable metrics. Cain’s Jiu Jitsu instructor and adult training-partners have all remarked on his physical development and increased strength this past year. I am aware some of this is biological. However, I am confident its been enhanced by training at MB. We are planning on having our youngest, Cash 9yrs (football and Brazilian Jiu Jitsu) start training there consistently this Summer.
