is looking the picture of health and fitness as she hits the red carpet and enjoys a new phase of her Hollywood career, and friends say she’s totally overhauled her fitness routine since turning 60.

“Lori has always been active and very fit but she really stepped it up this past year, she wanted to see how fit she could get,” an insider exclusively tells In Touch about her wellness regimen.

Pals close to the Full House actress have been applauding her dedication levels and say the results are speaking for themselves. “She started lifting much heavier weights, she has a personal trainer so it was all very controlled and safe and she gradually increased the weight with the goal of building lean muscle,” according to sources.

Those close to the When Calls the Heart star reveal that she has stuck to a regimen that involves building strength and gaining flexibility.

“Lori is convinced her five-days a week gym habit has helped her skin. She’s also very devoted to her yoga practice, she pretty much does an hour every day, and usually it’s hot yoga, done in sauna level heat, to help her detox at the same time,” say insiders.

Plus, “she runs at the beach some days but her preferred way to get her cardio in is to take an aerobic dance class, like Zumba.” Sources add, “Lori treats her fitness like a part-time job and it shows, she looks a good twenty years younger than she is.”

Lori dressed to impress during a public appearance in April, hitting the red carpet in honor of An Unforgettable Evening, a gala benefiting the Women’s Cancer Research Fund held at The Beverly Hilton.

The mom of two, who shares daughters Isabella “Bella” Rose, 26, and Olivia Jade, 25, with , dazzled in a fitted black lace midi dress paired with a choker necklace, linked bracelet, black Chanel bag and matching pointed toe stiletto heels.

She opted for bronzed glam and a voluminous curled hairstyle for the star-studded event.

In recent years, she has been making a comeback professionally in the wake of her college admissions scandal famously dubbed “Varsity Blues,” for which she and the fashion designer, 62, were both indicted in April 2019. Mossimo and Lori have been married since 1997.

The couple faced fraud charges after shocking claims they paid admissions fixer $500,000 for the University of Southern California to recruit their daughters onto the school’s rowing team, despite neither of their girls having any background in the sport.

Mossimo and Lori both pleaded guilty in May 2020. She was sentenced to two months behind bars along with a fine of $150,000 and 150 hours of community service. Lori was released in December 2020.

Her husband, for his part, was released in April 2021 after serving a five-month sentence and being ordered to pay a $250,000 fine and complete 250 hours of community service.

Lori has since returned to the small screen with roles on When Hope Calls, Fall Into Winter, Blessings of Christmas, Curb Your Enthusiasm and On Call.
