The best personal training gym on the South Shore

What makes us different

Let us show you why our members say they’ve never stayed at a gym as long as they’ve stayed with us (nearly 6 years, on average).

Small-est Group Training

When it comes to fitness, everyone deserves a tailored solution – that’s where small group personal training comes in. Since we opened in Weymouth in 2017, we’ve exclusively used a “semi-private” model where every member receives their own, individual program. Groups are limited to four members per coach, giving us significantly more time with each member than bigger groups or classes can afford. And we offer 35 small group training hours across mornings, evenings, and Saturdays.

A Gym with Personality

We’ve never sought to be a performance or sports facility designed for athletes. Instead, we continuously strive to be a space where you can train hard every rep, but laugh in between each set. Make no mistake, we are a gym. JMF is fully stocked with bars and weights and bikes and turf space. But you’ll also find meticulously clean facilities, brightly colored walls, and a fridge full of complimentary water. Plus, if you’re lucky you might just get a session with Lily & Marshall.

Ultimate Schedule Flexibility

Because of our individualized semi-private model, members can bounce around to different hours without having to worry if they fit into the time-slot. And since members complete personalized workouts, sessions can start a few minutes early, a few minutes late, or even on the half hour if that’s what your schedule needs. It doesn’t matter if you’re a seasoned gym-goer or have never worked out a day in your life, we don’t just train athletes – we train real people with families, fast-paced jobs, and crazy schedules.

Real people. Real results.

My first few times at the gym I was completely winded doing the exercises. I had to stop a few times because I was out of breath. Now I can get through the workout a little sweaty but not out of breath. I definitely feel stronger and have more energy. When I started at the gym I weighed 219 lbs. I now weigh 206 lbs.

Paul B.

I broke my ankle in February and came back to the gym after physical therapy in May. Since then I have been working out with weights and bands. I also have been using the treadmill for cardio. I definitely am getting stronger since coming back.

Cheryl B.

I joined the gym initially to try to build muscle. I needed help with programming to help me reach my new fitness goals. My most meaningful progress so far has been successfully benching 95lb. This was important to me because it shows the power of setting clear goals and receiving support from the gym community to reach them.

Megan D.

I joined the gym as I was looking to become more consistent with strength training. I was specifically having back issues and hoped a strength training program would help. Especially this year, I have seen significant progress in my form, the weights I have been lifting and how I have looked.

Chris D.

I have always struggled to stay consistent at any gym. JMF is the first place where I feel like I am committed to going. I started going to the gym to lose weight, but it quickly evolved into much more. The structure and discipline have helped me manage stress better and develop a more positive mindset.

Claire G.

I started out wanting to get better at football. The other kids always had that edge and I wanted to train to get better for the season. Being able to play varsity was one of my top goals leading up into the season and training helped me achieve that.

Brady S.

I recently hit 1,000 workouts at JMF. I have always been intimidated by gyms; by the time I got the confidence up to start trying to weight lift, etc. I was so far behind my peers that I just wrote it off. Being able to have something that shows six years of hard work, consistency, and pushing myself means the world to me.

Patrick W.

I never imagined myself lifting a trap bar or pushing a sled or frankly anything else I've done over the last month or year. I feel so strong and powerful! My confidence has grown so much, and that has trickled over into other aspects of my day-to-day.

Carolyn A.

Wow! Reaching 2 years of training and I've kept my weight off ! Even I cant believe it. I have exceeded my original goals and have finally accomplished something I was "gonna" do for the last 20 years. This has been an invaluable investment in myself, best money I have ever spent.

Bill R.

I have greatly surprised myself at how far I’ve come since joining JMF! My greatest achievement so far is simple: regular push-ups—4 total! I’ve gotten so strong and my back pain is so much more manageable— I feel like I won’t “throw it out” by just bending over to pick something up.

Sarah M.

My son was getting married and I wanted to look nice for the wedding. Now that I have been going for a while, I like how I feel stronger and the camaraderie within the gym is awesome. I was able to drop 20 pounds before the wedding and I looked pretty darn good in my dress!

Gayle J.

I first started training at JMF because I knew I needed to add strength training to my routine. Josh and Erin will start slow with you to see where you are at and then build off that as time goes on. Don't be afraid to try new exercises. You’ll be amazed at how great they make you feel.

Marjorie R.

I was surprised at how fast I felt myself making progress! Every time I add weight to the bar or move up to a heavier dumbbell or kettlebell it feels a little like I’m increasing my health points. And knowing other people are showing up and putting in the work makes it feel a little easier to do it myself.

Al F.

I started to try something different rather than continuing doing the same things over and over at the gym. Unfortunately, in February I was in a snowmobiling accident in which I tore my rotator cuff in my shoulder. During the past six months prior to my surgery I have been able to improve from almost zero mobility of my arm to almost 100%.

Greg R.

I think my most meaningful progress has been being able to cross over into what has now become a routine, being able to come at regular times each week and now having the mindset where I look forward to coming to train each day instead of it feeling like a chore as in years past.

Joe E.

I've never been a stranger to the gym, but I decided I needed align with a guide to try to hit a goal or two. I do my best to not miss a session and try to maximize effort at each session.

Marco G.

I first started to help control my type 2 diabetes and to better my overall health. It was hard to take the first step, but that was almost a year ago and now my visits are entrenched as part of my daily routine. With Josh, Erin, and the other members, it is by far the most comfortable gym setting I have ever experienced.

Peter F.

I originally joined because had a trip last summer to Run in the Alps. I’ve been a runner for more than 30 years and have run 29 marathons but knew I should add weight training to make it through the alps. The most meaningful progress has been noticeably increased core strength. I didn’t know I had abs! I just feel stronger.
