CORLISS STRENGTH CO.Providence, RI Book your free Day One
The Corliss floor: six black racks under CORLISS STRENGTH CO. painted on the old mill brick, low November sun across the concrete.

We know your name.Day 90, your numbers.

Coached small-group strength in an 1890s Providence mill. $175 a month, flat for a year. Your first hour is free.

60 minutes with a coach. You leave with three numbers to beat.

What $15 can't buy

There are two $15 gyms down the road.
They're fine.

Nobody there will notice you skipped Thursday. Here, someone will. That's most of what $175 buys, and it's the part that gets people strong.

$175 a month, flat for a year. It buys a coach, not a key card.

Four coaches

About 190 members.
Four coaches who know every one.

You'll meet all four in your first two weeks. By the third, they'll know what you pulled last Tuesday.

Jess Kowalczyk

Your first 90 days

Jess runs every Day One and owns every new member's first 90 days. She takes your three numbers, films your first deadlift, and texts you that night with what you pulled. She's 27, from Pawtucket, and she's very hard to ghost.

Ask her aboutthe card. Everyone gets one.

Frank Medeiros

Head coach

Frank competed as a powerlifter for years and has coached more deadlifts than he can count. He's 52, he carries a stopwatch on a cord, and he talks quietly enough that the whole room leans in. He sets how every test at Corliss is run, so day 90 means the same thing for everyone.

Ask him aboutthe one cue he gives everybody.

Marisol Peña laughing at the rack, chalk on her hands and leggings.

Marisol Peña

Barbell and Olympic lifting

Marisol threw shot put in college and grew up in Providence. She coaches the squat, the clean and anything with a barbell on your back. She's 34 and she's the laugh you hear from the other end of the mill, usually right after somebody's best set.

Ask her aboutwhy your squat stops halfway.

Knees, comebacks, and members over 60

Kofi was a physical therapist before he was a coach. Bad knees, old surgeries, a back that's been "fine, mostly" for ten years: that's his lane. He's 41, he keeps a pencil behind his ear, and he'll write down exactly where you start without making a face about it.

Ask him aboutthe box squat. It's how most comebacks start.

The First 90

Three numbers on day one.
The same three on day 90.

Most people don't quit a gym in a week. They fade around month two, when nobody's measuring and nobody notices. So we measure, and somebody notices. Here's exactly what happens.

The Tuesday whiteboard: back squat 5x5, RDL 3x8, sled and carries, and a red box of this week's PRs.
  1. 1

    The Pull.

    A trap-bar deadlift, your heaviest clean set of 5. Not a max.

  2. 2

    The Press.

    Push-ups, as many clean ones as you have. Off a box is fine; we write down the height.

  3. 3

    The Engine.

    A 500 m row for time, or a farmer's carry.

Plus one number we don't test.On Day One you tell Jess what you want to be able to do. "Carry both kids up the stairs." "Deadlift my bodyweight." She writes it down in your words. On day 90 she reads it back to you.

  1. Day 1 · Your Day One.

    60 minutes with Jess. One lift taught properly, filmed on your phone. Three numbers on your card. Your first two classes booked before you leave.

  2. Day 1, that night.

    A text from Jess with your numbers in it.

  3. Your first class.

    You're introduced to the room by name and paired with someone who's been here a while.

  4. Week 2 · First check-in.

    15 minutes. Is the schedule working, does anything hurt, one form fix on video.

  5. Week 4 · First win.

    One number re-tested in class. Usually the push-ups. Usually up.

  6. Week 6 · The midpoint.

    Your day-1 deadlift next to today's, on the same phone.

  7. Week 10 · The preview.

    Your re-test goes on the calendar. Jess tells you what's coming. She's usually smiling.

  8. Day 90 · The re-test.

    Same three tests, same way, same coach. Then the two videos side by side.

On day 90 we don't ask you to renew. We show you what you built and ask what's next.

You leave day 90 with three new numbers, a new date, and a coach who expects you. That's the whole renewal.

Before you book

Questions people ask before they book

I've never touched a barbell.

Good. Most Day Ones start with an empty bar, and you'll learn it right the first time. Nobody here will laugh.

I've got a bad knee (or back, or shoulder).

Tell us on the booking form. Kofi was a physical therapist; he'll know your Day One plan before you walk in.

Why $175 when there's a $15 gym nearby?

Because $15 buys the room and $175 buys the coaching. If you want the room, go there; it's a fine room. If you want someone to know your name and fix your deadlift, come here.
