The defiant New Jersey gym that was shut down for violating the state’s coronavirus lockdown reopened its doors Friday morning to cheers from over three dozen supporters — but otherwise little fanfare.

Thirty gym junkies streamed into Atilis Gym — which has been open for most of the week in defiance of Gov. Phil Murphy’s stay-at-home executive order — for their morning workout, as a handful of patrons waited outside.

“My biggest concern is staying in business and standing up for what we decided to stand up for in the first place, which is our constitutional rights,” Atilis Gym owner Ian Smith said outside the Bellmawr gym, alongside co-owner Frank Trumbetti.

On Thursday, the owners arrived to find notices from the state and county taped to its doors ordering it shut. But they promised to reopen Friday at 20 percent capacity — 44 people every 90 minutes — and with other strict social distancing measures in place.

Smith and Trumbetti have received several disorderly conduct summonses since reopening their gym on Monday amid a tense standoff with police.

Patrons are required to wear face masks and undergo temperature scans at the door. Workout equipment has also been spaced out and the gym is cleaning the air with a disinfecting UV light. A bodyguard was also on scene Friday to enforce the gym’s social distancing rules.
