5.3 a week · 2,498 lifetime. Opened the year at 15 sign-ins in January and has not been under 19 since March.

929 lifetime · seven of eight months in the club this year, and August was the best of the seven.

1,122 lifetime · back-to-back 23s, and eight-for-eight on the year.

2,733 lifetime · four #1 or co-#1 finishes in five months. A residency, not a run.

January through August. 15+ sign-ins every single month. No gaps, no vacation asterisks:

Mandy Pant · Abhi Das · Lisa Zancewicz · Rob Scannevin · Shana Doiron · Marc Dobay · Maria Maynard · Damon Walsh · Shreeja Pillai · Carolyn Keiper · Tyler Moore · Emily Oberlee

Eight for eight. Two thirds of a year without a single ordinary month.

Seventeen members were perfect through July; twelve carried it through August. And right behind them, 13 more members have missed exactly one month all year — including Liz Nasser, Griffin Barriere, Sandy Brock, Nicole St.Pierre and Anne Leahy. Shreeja Pillai deserves her own line: 15, 16, 16, 15, 18, 19, 19, 18 — she has never once over-reached, and she has never once missed.

Thirteen sign-ins across the first seven months of 2026. Seventeen in August alone. Leanne has 30 lifetime classes at PTS and more than half of them happened last month — her first Committed Club, ever. The best kind of number on this page.

January through June: 21 sign-ins total. July: 18. August: 18. Something changed at the halfway point of the year, and it has held for two straight months. He is now 13 classes from 250 lifetime.

13, 13, 13, 13, 14, 13 — six months of landing just under the line. Then 18 in July and 20 in August. Nobody in the gym spent longer knocking on this door.

Every one of Melissa’s 33 lifetime classes has come since July. She made the Committed Club in her first month at PTS, then raised it to 18 in her second. She has never had a month here that wasn’t a Committed Club month.

Xiao Zhang put up 20 sign-ins against 114 lifetime; Samet Oksak 16 against 56; Kathleen Sexton 16 against 110. Roughly a fifth of everything they have ever done here happened in one August.

The pairs held the line in August: Griffin (23) & Garrett Barriere (18), Liza (20) & Jon Davis (17), and Carolyn (17) & Cornelius Keiper (18). The easiest way to keep a habit is to share it.

It is our monthly recognition for any member who records 15 or more sign-ins in a calendar month at Prototype Training Systems in Westborough, MA. Fifteen sign-ins is roughly three and a half sessions a week — the level of consistency that actually changes how you look, move and feel. There is no application and no fee. You show up, the data finds you.

All of them. Group Class, Open Gym, Personal Training, Endure, Thrive, Longevity and Recovery sessions all count equally. A recovery session on a tired Thursday counts the same as a Friday barbell class, because showing up on the tired day is the harder rep.

45 members, with 811 combined sign-ins and an average of 18 sign-ins each. The top count was 23, shared by Liz Nasser, Griffin Barriere, Mandy Pant and Abhi Das.

Twelve members are eight-for-eight from January through August: Mandy Pant, Abhi Das, Lisa Zancewicz, Rob Scannevin, Shana Doiron, Marc Dobay, Maria Maynard, Damon Walsh, Shreeja Pillai, Carolyn Keiper, Tyler Moore and Emily Oberlee.

Book 15 sessions and keep them. Three to four a week, every week, with no perfect stretch required — most members on this list get there with a standing Monday/Wednesday/Friday plus one weekend session. If you are not a member yet, start with a free intro at prototypetraining.com.
