Build Strength. Build Muscle. Feel Athletic Again.
Ross Fitness is right next door in Ayer — minutes from anywhere in Devens. Semi-private coaching, your own program, and Kyle coaching every workout. Max four to a session.
Devens has grown fast — but an apartment fitness room or a swipe-in gym won't get you what real coaching does. At Ross Fitness, right next door in Ayer, you're not left to figure it out alone. You get a real coach, a real plan built around your body, and a room of serious adults who notice when you're not there.
We already coach members from Devens and right around Ayer — and most say the same thing: they finally stopped guessing, stopped getting hurt, and started getting strong. If whatever you're doing now isn't moving the needle, this is the difference between working out and being coached.
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.
Ross Fitness is at 12 Central Ave in Ayer — just a few minutes from Devens, right next door. Free parking right outside. Morning sessions Mon–Fri 5 AM–1 PM and Sat 6–11 AM.

In 10 years of individual and group sessions with Kyle, I've lost — and maintained — 25 lbs and 3 pant sizes, recovered from a skiing-related ACL replacement, and still look forward to every workout. He personalizes everything and challenges you to reach goals you didn't know you had.
Theresa R. · Nashoba ValleyJust a 5- to 8-minute drive (about 2–3 miles) — Devens is practically our backyard. We're right next door at 12 Central Ave in Ayer, with free parking outside.
Yes — because this isn't a gym, it's a coach and a system. Sessions are capped at 4, every program is built around your body, and Kyle coaches every rep.
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.
Ross Fitness 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: Ayer, Shirley, Harvard, Groton, Littleton.
The Rebuild Six is my free daily mobility system — four short follow-along tracks for stiff hips, achy low backs, cranky shoulders, and desk-bound bodies. No equipment. Real coaching videos.

Thomas B. · Nashoba Valley“After 5 weeks the results took me by surprise. He's a motivator and mentor who treats every person who walks through that door like family. Give him your dedication and you WILL see results.”
Eric C. · Nashoba Valley“I've known and worked with Kyle for 8 years. The clients vary from Division 1 Quarterbacks to middle-aged ladies and young adults — he adapts the workout to fit every individual.”
