Real reason why Jennifer Aniston does punishment training revealed

“On days when her schedule is completely full, she sets her alarm for 4 a.m. to make sure she can exercise,” she added.

“Missing training isn’t an option for her right now, especially with the wedding looming, and that determination informs every part of her daily routine.”

Aniston’s discipline also extends to diet, with friends saying she follows a regimen of eating balanced meals and a morning routine that includes warm water, ginger, honey, lemon and supplements.

Aniston was first linked to Curtis last summer, with the couple publicly confirming the relationship towards the end of the year and spending the holidays together.

She has described him in interviews as “very special” and “grounded” – language sources say it reflects a sense of calm in contrast to the intensity of her current physical regimen.

A source emphasized that the marriage speculation has tightened everything for the actress.

“Jen has always been committed to fitness, but this time she has a very specific endpoint in mind,” the insider added.

“She’s driving herself harder than ever before because she wants to walk down the aisle and feel powerful, confident and completely flawless in front of Jim.”
