Jennie Garth is seen staying active at the gym with personal trainer

Beverly Hills 90210 alum Jennie Garth refuses to let her battle with arthritis stop her from staying fit and active, exclusive new photos show.

The 51-year-old actress, who has revealed she was diagnosed with osteoarthritis three years ago, was photographed last week arriving at the gym in the San Fernando Valley for an intense personal training session.

The What I Like About You star looked healthy and fresh ahead of the workout for which she wore black sweatpants, a gray tank top and Nike Air Max 270 sneakers.

She pulled her blonde hair back into a bobby ponytail and brought a bottle of water to stay hydrated.

Garth also took to Instagram to share videos of the pair having a little fun between reps and sets of exercises.

She filmed how she surprised her trainer Jason with a t-shirt featuring her character Kelly Taylor and her iconic quote: “I choose me.”

The fitness expert even posed in the T-shirt that was three sizes too small.

She first used the phrase in 90210 when her character Kelly Taylor was being pursued by both Luke Perry’s Dylan and Jason Priestley as Brandon – but she decided neither was good enough for her.

On his way out, Garth was seen stopping to hug an adoring fan and even posed for a few selfies with him.

She took her to the car with her trainer and the pair chatted for a while before she went home.

The mother-of-three opened up about her medical condition in an interview with Insider last May revealed how the degenerative joint disease led her to hire a personal trainer to deal with the pain and stay as active as possible.

She told the outlet that she went to a doctor after she started experiencing pain in her knees when she went from sitting to standing, as well as stiffness in her fingers and hands.

Garth admitted them was not upfront about her condition because she “didn’t want to be that person who talks about their ailments.”

She was diagnosed with the most common form of the condition, which occurs after the cartilage that protects the ends of bones wears away, resulting in irreversible tissue damage.

She told People magazine, “Going to a doctor or specialist and getting that diagnosis is key, because with that knowledge we can do our job.”

She added, “It spurred me on to be more physically active and work with a trainer.”

The diagnosis came amid a tumultuous year for Garth, whose third husband Dave Abrams filed for divorce in 2018 after three years of marriage citing irreconcilable differences.

The couple separated but got back together ten months later and have remained married till now.

This isn’t the 90210MG podcaster’s first health scare. In 2002, she was diagnosed with mitral valve prolapse and a leaky heart valve, but she did not disclose this until 2009.

Despite her health issues, Garth has continued to act and was seen at the ATX TV Festival in Austin on Thursday.

Earlier this year, Garth sent 90210 fans into a frenzy when she reunited with former co-stars Tori Spelling, Jason Priestly and Ian Ziering at 90s Con in Memphis, Tennessee.
