Hammer Challenge Series returns to Hudson Fit Expo on Sept. 12 with HCS 37, bringing submission-focused Jiu-Jitsu superfights to St. Peter’s Prep during a full day of fitness competition in Jersey City.
JERSEY CITY, N.J. — Hammer Challenge Series returns to Jersey City on Saturday, Sept. 12, for HCS 37 at Hudson Fit Expo, putting regional submission grappling in front of an audience that extends well beyond the traditional Brazilian Jiu-Jitsu crowd.
Hudson Fit Expo’s official schedule gives Hammer Challenge Series a 10 a.m. to 12:30 p.m. competition block at Saint Peter’s Prep James F. Keenan, S.J. Field, 201 Marin Boulevard. The expo lists the segment as “Jiujitsu Showdown 14C,” with HCS 37 delivering action-packed grappling superfights. The full Hudson Fit Expo runs from 9 a.m. to 8 p.m.
As of Sept. 3, the official ticket listing shows $50 advance admission and $75 at the gate, with doors scheduled to open at 8:45 a.m. One Hudson Fit Expo ticket provides access to a day that extends well beyond Jiu-Jitsu, making HCS 37 an unusually accessible entry point for spectators who may never have attended a dedicated grappling show.
Hammer Challenge Series Returns to a Familiar Jersey City Crowd
This will not be HCS’s first appearance at Hudson Fit Expo.
Hammer Challenge Series brought submission-only superfights and team competition to the 2025 Hudson Fit Expo, where matches took place outdoors on Newark Avenue’s pedestrian plaza. Hudson Fit Expo later praised the tournament and confirmed plans to bring HCS back for 2026.
This year changes the setting. HCS 37 moves with Hudson Fit Expo to St. Peter’s Prep, where the broader event will combine Jiu-Jitsu with powerlifting, sumo, strength competitions, calisthenics, hybrid fitness events, group workouts and a large vendor area.
Hudson Fit Expo promoted the returning grappling portion in an Aug. 26 post as “Battle 14C,” telling followers that Jiu-Jitsu and grappling would return through Hammer Challenge Series and inviting people to compete or watch.
For HCS, the expo creates a useful crossover audience. A spectator may arrive to watch powerlifting or meet a fitness personality and find submission grappling happening a few yards away. That exposure matters for a regional sport still trying to make high-level Jiu-Jitsu understandable and entertaining to people who do not train.
Why HCS Matches Look Different From a Standard BJJ Tournament
Hammer Challenge Series has intentionally built its rules around forward movement and decisive action.
The promotion’s official rules make adult matches submission-only during regulation. White- and blue-belt superfights receive four minutes, while purple-, brown- and black-belt professional matches run six minutes. Grand Prix matches receive eight minutes. When regulation does not produce a submission, HCS moves into its own overtime structure rather than simply relying on a conventional advantages-and-points format.
HCS also penalizes stalling and uses a defined competition area designed to limit the ability to disengage indefinitely. That structure reflects promoter Josh Baker’s stated goal of making grappling more watchable without stripping away the technical decisions that make Jiu-Jitsu difficult.
That philosophy has become a recurring theme in JMurrayAthletics’ coverage of the promotion. In JMA’s recent feature on Baker, he explained how HCS evolved from six matches streamed on an iPad into a promotion built around shorter matches, a circular competition area, Grand Prix tournaments, team duels, championships and developmental opportunities.
The Hudson Fit Expo setting may provide one of the best tests of that concept. HCS will perform in front of both dedicated grappling followers and casual fitness fans who may judge the product much more simply: is this exciting enough to stop and watch?
HCS 37 Competitors Have Been Preparing for the Ruleset
The buildup has already extended beyond event posters.
Rolling Bear Brazilian Jiu-Jitsu documented an Aug. 19 collaborative training session specifically organized around the upcoming HCS card. The academy said athletes completed more than 90 minutes of situational and live rounds tailored to the Hammer Challenge Series ruleset, with HCS athletes and competitors from Rising Sun BJJ Academy joining the session.
That preparation gives the upcoming Hammer Challenge Series Jersey City event more context than a collection of athletes showing up for isolated superfights. Competitors are drilling for HCS-specific situations, particularly the pace, boundaries and overtime scenarios that can punish someone who approaches the match like a conventional tournament round.
The final matchup list remains important because regional grappling cards can change quickly. Baker recently told the JMA Podcast that one of the realities of matchmaking is that “the card you announce is rarely the card you actually get.” His job frequently involves rebuilding matches around injuries, withdrawals and new competitive opportunities.
That makes HCS’s current social announcements the right place to follow the card through fight week rather than relying on an older lineup.
JMA Has Already Followed the Road Toward Hudson Fit Expo
Some of the competitive stakes surrounding September have been developing for months.
In JMurrayAthletics’ July preview of Hammer Challenge Series Fight Night 4, veteran Dallas Ragusa was specifically described as working toward an anticipated 135-pound Grand Prix at the Hudson Fitness Expo. That same card included Wildcard champions, developing HCS prospects and competitors trying to improve their position for future opportunities.
The current Hudson Fit Expo schedule now describes HCS 37 broadly as “grappling action packed super fights,” so the final Sept. 12 format should follow HCS’s latest announcements rather than the earlier July projection.
That evolution is typical of Hammer Challenge Series. HCS uses Fight Nights, wildcard events, team duels and larger numbered shows as interconnected parts of its competitive system. Its FAQ allows qualifying athletes to work toward Grand Prix opportunities through HCS records, prior championships and wildcard tournaments rather than treating each event as a disconnected booking.
JMurrayAthletics has followed that progression throughout 2026, including HCS 32, HCS 33, multiple Fight Night cards and the promotion’s Grand Prix events. Readers who want more background on the promotion can also revisit JMA’s coverage of HCS 33, which featured Antonio Covello, Cole Allem, Jenna Sylvester and Joey Gaffin as the promotion continued expanding its New Jersey roster.
Hudson Fit Expo Gives HCS 37 More Than a Normal Grappling Audience
The biggest promotional advantage for HCS 37 at Hudson Fit Expo may have nothing to do with the match card.
Hudson Fit Expo advertises eight live competitions, group workouts, more than a traditional single-sport crowd, wellness activations, vendors, giveaways and appearances from figures including Larry Wheels. The event runs for roughly 11 hours, while Hammer Challenge Series occupies a concentrated two-and-a-half-hour window early in the day.
That creates a simple plan for fight fans: arrive for HCS 37, then stay for the rest of Hudson Fit Expo.
It works in reverse, too. Someone who buys a ticket because of strength sports or fitness culture gets an opportunity to watch regional submission grappling without purchasing another event ticket.
That crossover is why the two stories deserve separate JMurrayAthletics coverage rather than forcing every Hudson Fit Expo attraction into one oversized preview. HCS 37 deserves its own article for BJJ and Hammer Challenge Series searches; Hudson Fit Expo deserves a second guide for people searching the complete Jersey City event.
Why HCS 37 Is Worth Watching
Hammer Challenge Series has grown by giving regional athletes a place to compete regularly rather than waiting months for one tournament appearance. HCS Fight Nights allow newer competitors to develop, while championships, team competitions and Grand Prix opportunities give established athletes something larger to chase.
The formula also gives spectators something easy to understand. Regulation revolves around finding a submission. Stalling costs competitors. If neither athlete finishes, overtime forces another decisive sequence.
HCS describes itself as “The House Party of Grappling.” The phrase fits the promotion’s close-quarters events, but Hudson Fit Expo gives that identity a different scale. Instead of asking spectators to find a dedicated grappling venue, Hammer Challenge Series will place HCS 37 inside one of Jersey City’s broader fitness events.
For New Jersey BJJ fans, that makes Sept. 12 straightforward: HCS 37 brings Hammer Challenge Series back to Jersey City, the matches start at 10 a.m., and one ticket opens the door to the entire Hudson Fit Expo experience.
