Ben Affleck’s ex is allegedly helping him shed big gut in a special boot camp amid public fights

It seems Jennifer Garner has been helping Ben Affleck get back in shape after preparing a personalized boot camp for her ex-husband.

According to an insider report from RadarOnline, their children have been very concerned about their father's health after he gained a significant amount of weight after the separation of their parents.

"Jen's agreed to help him because their kids are so concerned about his health!"

And there is no one better to help Affleck than his ex-wife Jennifer who seems to have been in her best shape.

"Jen is shredded! She worked out three hours a day for her new movie 'Peppermint' and is totally ripped."

Now, she is taking what she's learned from working out three hours a day and is sharing it with Ben in a personalized boot camp which she planned.

"She's got Ben doing cardio, weight and resistance exercises - sweating off fat and building muscle. She's even put him on a detox diet that includes smoothies made of veggies and fruit, along with a lot of lean protein like chicken and fish."

After the 'Batman' actor put a devastating end to their marriage due to alcohol and gambling addiction alongside cheating, it appears the 'Alias' star is having a great time controlling his workouts and diets says the insider.
