Private, fully individualized strength coaching for busy professionals.
If you're searching for one-on-one personal training in Boston, you're probably looking for more than a workout. You want a coach who builds the plan around you — your goals, your body, your schedule — and who's present for every rep.
At First Guess Fitness in Downtown Boston, 1:1 personal training means exactly that. No templates, no autopilot. Just a credentialed coach, a strength program built for you, and the structure to actually stick with it.
A quick conversation to see if 1:1 training is the right fit — no pressure, no commitment.
One-on-one training is the most personalized way to work with a coach. Every session is designed around:
No template, no one-size-fits-all programming. Your coach is focused entirely on you — your technique, your progress, and your long-term success.
One-on-one personal training is a great fit if you:
Most of our 1:1 clients are busy Boston professionals — attorneys, founders, consultants, healthcare workers — who want efficient, focused sessions that fit cleanly into their week.
Every 1:1 client works with one of our two credentialed coaches (with Scout supervising). We're a small team on purpose — we know our clients by name and program.

Our goal isn't to exhaust you — it's to help you build strength, confidence, and momentum you can sustain for years.

"This is the first time I've ever worked with personal trainers, but the staff here are wonderful. I've had sessions with Patrick, Justin, and Cory, and they are all incredibly knowledgeable and able to balance that with creating a fun, comfortable, and community-oriented environment. Definitely recommended if you're looking for personal training, private or semi-private, in Boston!"

At First Guess Fitness, coaching always comes first. While we're best known for our semi-private training model, 1:1 personal training plays an important role for people who need or prefer a fully private approach.
During your intro call we'll help you choose between 1:1, semi-private, or a combination of both based on your goals, schedule, and budget. If we believe another option would serve you better, we'll tell you — honestly.
Most Boston private training studios run $90–$160 per session. Our 1:1 personal training is priced in that range, with packages that bring the per-session cost down. Book a free intro call and we'll walk you through exact pricing for your goals and schedule.
For people who want maximum personalization, privacy, injury accommodations, or focused coaching every rep, 1:1 is the most effective option. If you want most of the benefit at a lower price point, our semi-private (6:1) program is a great alternative — we'll help you choose during your intro call.
Most clients train 2–3 times per week. Twice a week is the sweet spot for measurable strength and body-composition changes without taking over your schedule.
Not at all. Many of our clients begin with little or no recent training experience. Our job is to teach you the lifts safely and progress you at the right pace.
1:1 is the best option for clients with injuries, post-rehab needs, or any condition where every rep needs to be coached. We work alongside your PT or physician when relevant.
There's no objective answer — the best trainer is one whose programming, personality, and approach fit you. Our coaches, Justin and Patrick, both hold advanced degrees and nationally recognized certifications and specialize in strength training for busy professionals. Book a free intro call and see if it's a fit.
We're at 30 Court Square in Downtown Boston, a 2-minute walk from Government Center T, 5 minutes from Faneuil Hall, and a quick walk from the Financial District. Street parking and several garages are within a block.
1:1 means a coach with you every rep, a fully individualized program, and total flexibility on timing. Semi-private (6:1) is small-group strength training on a fixed schedule with shared coaching attention — same programming quality, lower per-session price.
