A Long Island plastic surgeon who was caught with an arsenal of weapons in his car has found it difficult to swim since he was released on bail two weeks ago – and he needs to “because he’s prone to put on weight,” according to a report.

“This man poses no threat,” Dr. Matthew Bonanno’s lawyer Paul Gentile told Westchester County Judge George Fufidio on Tuesday, according to The Journal News/lohud.com.

“He can’t exercise because it hurts. He needs to swim because he’s prone to put on weight,” he added.

But his argument carried no weight with the judge, who said the doc can just wrap his ankle in a plastic bag.

“He’s a man of means and if he wanted to disappear he could disappear,” Fufidio said, according to the news outlet.

Bonanno, 47, was arrested in Tuckahoe on Aug. 12 after his friend told authorities that he threatened to kill his ex-wife and daughter while the two men were drinking at Growler’s Beer Bistro in the Westchester village.

During their probe, Tuckahoe police discovered a cache of assault rifles and unregistered guns, as well as 29 high-capacity magazines, 1,600 rounds of ammo, body armor, brass knuckles, a stun gun and other items in his BMW parked outside his ex-wife’s home.

Police then searched his parents’ home in the town of Mount Pleasant, where they found three additional unlicensed handguns. At the surgeon’s home in Great Neck, cops discovered additional weapons, police said.

Bonanno was charged with a 53-count indictment though he was never charged in connection to allegedly threatening to kill his family, according to lohud.

Fufidio vacated an order of protection that prevented the suspect from contacting his former wife after she said under oath she didn’t want it, the outlet reported.

The judge’s monitor condition was not changed when an appellate court reduced the original bail.

Bonanno has posted $70,000 bail to satisfy the charges in Westchester and Nassau counties.

Gentile, who has accused police and prosecutors of disseminating “false narratives” in the case, questioned why Fufidio was “so hardened” in his rulings. He suggested that the bail reduction should have led the judge to reverse his decision on the ankle monitor.

“The Appellate Division second-guesses every trial judge in the state,” Fufidio said. “I’m not concerned about them looking over my shoulder.”

Gentile also has asked the appellate court to move the Westchester case to the Bronx, claiming that the publicity has made it impossible for his client to get a fair trial in Westchester.

Fufidio ordered Bonanno back to court on Jan. 28
