the manager of the Giants. He and his wife, whom he met in his senior year of high school, are now divorced. Longtime Boston Globe columnist Bob Ryan—who said of Kapler "He's as smart as any player I've ever met"—nicknamed him "The Body". He is an avid weightlifter; his body fat count was reported in 2000 to be at 3.98%, and in 2012 to be at 3.5%. He was on the cover of several fitness magazines and became renowned for being the focus of an entire K-Swiss shoe campaign before he had even reached the pros. His blog discusses fitness, nutrition, health, and leadership. Kapler and his wife co-founded the Gabe Kapler Foundation, which is dedicated to educating the public about domestic violence, and helping women escape abusive relationships. In a clubhouse poll, it was once revealed that of the 25 players on the Red Sox, 24 were Republicans and Kapler was the one Democrat. Kapler's father died in December 2020 from Parkinson's disease and Lewy body dementia. Prior to the start of the 2022 season, Kapler received a prominent tattoo on his left hand to memorialize his father. Jewish heritage Kapler is Jewish, and to honor his heritage, has a Star of David tattooed on his left calf, with the inscription "Strong Willed, Strong Minded" in Hebrew, and the post-Holocaust motto "Never Again" with a flame and the dates of the Holocaust on his right calf. He describes his background as "culturally Jewish.... I was—and am—proud of my heritage, but don't practice religion," and as to being a Jewish Major Leaguer said: "That's something I take great pride in.... I'm very interested in my heritage and I'm very proud of who I am." He has 14 total tattoos. Kapler has been given the nickname Hebrew Hammer due to his frequent longball hits, along with his muscularity and the fact that he is Jewish. It later became the nickname of Ryan Braun, who is also Jewish, and was Kapler's teammate on the Brewers. On August 8, 2005, while playing for the Red Sox, Kapler took the field in the 9th inning along with Kevin Youkilis and Adam Stern, setting a "record" for the most Jewish players on the field at one time in American League history and the most in Major League Baseball history since four Jews took the field for the New York Giants in a game in 1941.
