One coach, one studio: RiNo, Denver, and online wherever you are. Plans from $29 a month.

Coaching that fits your week.

Train with me in the studio, follow my plan on your own, or both. Every plan starts from a movement check and changes every four weeks with what you can do.

I'm Theo Marsh.

A line cook until 27. A coach for nine years.

I hurt my back lifting a stockpot. A physio put me on a deadlift programme, and within a year I was stronger than I had been at twenty.

Now I coach people with jobs, kids and bad knees. Every session is planned before you arrive, every rep is watched, and the weight goes up when you are ready, not before.

    One-to-one

    An hour with nobody else on the floor. I set up every lift, watch every rep and change the weight as we go.

  • Two lifting chains hanging against the concrete wall

    Online

    Your plan in the app, video form checks answered within a day, and a call every second week.

  • The power rack with a bench and an empty bar

    Nutrition

    Protein and portion targets built around what you already cook. No shakes to buy, no foods banned.

  • A leather lifting belt on the chalky floor

    A goal

    Twelve weeks toward one thing: a first pull-up, a 300 lb deadlift, or lifting again after an injury.

In their words.

Nurses, electricians, teachers and a firefighter, in the studio and online.

  • “I had never touched a barbell at 44. Eight months in, I deadlift my own bodyweight and my back stopped hurting at work.”

    Karen D. · Dental hygienist

  • “He filmed my squat in the first session and showed me why my knees caved in. Fixed in three weeks.”

    Marcus T. · Electrician

  • “The online plan fits around twelve-hour shifts. When my rota changes he moves the week, no fuss.”

    Priya S. · ER nurse

  • “No shouting, no supplements to buy. A plan, and someone who notices when I skip it.”

    Ben A. · Software developer

  • “I came to get ready for a wedding and stayed for two years. Still the best hour of my week.”

    Laura M. · Teacher

  • “He wrote my meals around what I already cook. I eat more than before and I am down 19 lb.”

    Jorge R. · Restaurant manager

  • “First pull-up at 38. It was in the plan from week one, and I did not believe him.”

    Sam K. · Architect

  • “After knee surgery my physio sent me here. Theo works from her notes and checks in with her.”

    Dana W. · Accountant

  • “The studio is quiet and there is never a queue for the rack, because it is only you.”

    Chris L. · Firefighter

  • “Feedback on my videos the same day, every time. That is what I pay for, and I get it.”

    Aisha N. · Product manager

Before you sign up.

Do I need to have trained before?

No. Most people start with no gym history. The first session shows me where to begin, and the first four weeks are mostly learning the lifts.

Where is the studio, and can I park?

Unit 104 at 3350 Brighton Blvd in RiNo, on the ground floor. There is street parking on Brighton and two marked spaces behind the building.

Can I switch plans later?

Yes, from the next month. Tell me a week before your renewal date and the new price starts then.

What do I need for online coaching?

A phone for the app and for filming your sets, and a gym with a barbell and dumbbells. With dumbbells and a bench at home, I can write a home plan.

How soon will I notice a difference?

Most people lift more within three weeks and feel it in daily life after six to eight. Changes in the mirror take longer and depend on food as much as training.

Book a movement check.

The first session takes 45 minutes: we talk about what you want, then I check how you squat, hinge, push and pull. It costs $35, taken off your first month if you join.
