CHICAGO — As the Mets consider methods to keep their players on the field and off the disabled list next season, they remain committed to their senior advisor for strength and conditioning, Mike Barwis.

“Mike is not going anywhere,” general manager Sandy Alderson told The Post on Wednesday before the Mets faced the Cubs at Wrigley Field. “Mike is one of our most important staff and resources.”

In a season in which the Mets have been decimated by injuries, losing star players for extended periods, Barwis has become a target among fans, especially after a video was produced before the season that showed Yoenis Cespedes performing 900-pound bear squats with his legs at Barwis’ facility.

Cespedes, who late last month was declared finished for the season with a strained left hamstring, played just 81 games in 2017, after twice hitting the disabled list with leg ailments.

Also, Noah Syndergaard, the staff ace, has been sidelined since May 1 with a torn right lat and it’s unclear if he will return this season.

Barwis, a former strength and conditioning director at the collegiate level, is completing his third year overseeing the Mets’ workout programs.

He is the founder and CEO of the Barwis Methods, an international conglomeration of training centers, manufacturing and distribution companies and affiliated charities related to strength and conditioning, human performance and injury recovery, according to his bio in the Mets media guide.

“The perception that some people have of what Barwis provides to the Mets is completely erroneous,” Alderson said. “He provides mostly training in the offseason and there are a couple of misconceptions.”

Alderson said one misconception is Barwis was responsible for Syndergaard’s offseason training. The right-hander, who worked out independently last winter at a facility near his home in Mansfield, Texas, reported to camp boasting that he had added 17 pounds of muscle.

“Barwis had nothing to do with Syndergaard’s offseason training,” Alderson said.

And the GM took issue with the notion Barwis was too cavalier in his handling of Cespedes last offseason, highlighted by the video and an ESPN segment with the bear squats.

“Cespedes didn’t do any of that kind of exercise with any of his work with Barwis,” Alderson said. “It was filmed, I think, because somebody wanted to demonstrate how strong he might be and it has left a completely erroneous impression.

“It wasn’t part of his training and, in fact, Mike Barwis is probably key to keeping Cespedes on the field going forward. The guy that Cespedes most trusts is Barwis.”

An organizational source said it was Cespedes who wanted to perform the heavy lift for the video and TV segment, even though Barwis was against it.

Cespedes, upon sustaining his second hamstring injury this season last month in Washington, indicated he still has faith in Barwis and plans to change his routine next offseason.

A club source said the fact there have been so few commonalities in the players’ injuries make it difficult to pin the blame on Barwis, who first began working with the Mets as a consultant following the 2013 season, when several players attended an offseason boot camp in Ann Arbor, Mich. After the following season, he was hired to oversee the Mets’ major league and minor league strength and conditioning programs.

Among the other Mets’ injuries that have crippled the team for significant stretches this season: Jeurys Familia (blood clot in his right shoulder), Matt Harvey (stress injury in his right scapula), Michael Conforto (dislocated shoulder and torn posterior capsule), Steven Matz (ulnar nerve) and Seth Lugo (partially torn ulnar collateral ligament).

“You can say the team went to the World Series two years ago and the playoffs last year with Barwis, so maybe this is just an anomaly,” another source said.
