Build Strength. Build Muscle. Feel Athletic Again.
A bunch of your Groton neighbors already train at OTB — a short drive down the road in Ayer. Semi-private coaching, your own program, and Kyle coaching every workout. Max four to a session.
Groton runs busy — work, kids, commutes, and a gym membership that mostly gathers dust. A treadmill and a wall of machines was never the answer. What actually changes your body is coaching: a plan built for you, and someone making sure you do it right.
We coach a bunch of members from Groton who were tired of starting over every January. With max 4 to a session and Kyle on the floor every rep, they finally got consistent — and got strong. It's a short drive that pays you back every single week.
Built around your body, your history, and your goals — never a shared template off a screen.
Every session, the owner — not a rotating junior trainer. 20,000+ hours on the floor.
Real attention and hands-on cueing on every rep. You're never lost in a crowd of 25.
Post-rehab specialist coaching. We train around your bad back or knee, not through it.
OTB is at 12 Central Ave in Ayer — roughly a 7-minute drive from Groton. Free parking right outside. Morning sessions Mon–Fri 5 AM–1 PM and Sat 6–11 AM.

I was a burnt-out ex-collegiate swimmer who'd tried every fad diet. Kyle made the gym fun again. My biggest takeaway has been confidence — I've gained muscle, lost inches, and a sense of confidence I haven't had since high school.
Heather P. · GrotonI've trained with Kyle for over 2 years and seen amazing results. The second I stepped into Ross Fitness I knew it was my forever home — personalized programs that are challenging and fun. By far the best investment in my health.
Suzanne B. · GrotonAbout a 6- to 8-minute drive (4–5 miles) — we're at 12 Central Ave in Ayer, with free parking right outside. Plenty of our members come over from Groton several mornings a week.
Our Groton members say yes without hesitation. A cheaper membership you don't use isn't cheaper — it's wasted. Coaching that actually gets you strong is what's worth the short drive.
Morning sessions only: Monday–Friday 5 AM–1 PM, Saturday 6–11 AM, closed Sunday. If you're an early riser who wants to train before the day takes over, it's a perfect fit.
That's exactly who this is built for. Every client starts with a movement screen, and Kyle is a post-rehab specialist — we train around your history, not through it.
OTB is premium, fully individualized, owner-coached strength coaching — not a big-box membership. We'll walk through the investment together at your in-person consult.
Train with me for two full weeks. If you don't feel stronger, more confident, and more capable than when you walked in, I refund every dollar. No questions, no fine print.
We coach members who drive in from across the area: Shirley, Harvard, Lunenburg, Littleton.
