Jennifer Aniston's new photos for her collaboration with Pvolve were released on Friday.
Fans went wild on Instagram with comparison for the 55-year-old siren, who appears to be in excellent shape.
Many said the images reminded them of Jane Fonda in the 1980s, only instead of wearing bright colors, Aniston was in jet back.
One follower even called the Friends veteran 'Jennifer Fonda.'
Fonda, 86, became the top workout guru from the eighties as she encouraged women to exercise in their living rooms via videos on their VCRs which were new at that time.

Aniston flashed her very muscular arms as she modeled a plunging black bodysuit as she looked like she just got a fresh tan in Malibu.
The size 0 workout enthusiast also shared a behind-the-scenes video where she was being filmed during a Pvolve workout.
At one point the sweaty Friends star was cooled down with what looked like a massive long-nosed fan that resembled a vacuum cleaner nozzle.
This comes after she revealed she is on the fad diet called the 16:8 Diet which involves intermittent fasting.
Jennifer has said she does Pvolve five days a week.
Her workout regime is cardio intense, while she also attends 10-to-20 minute Pvolve classes.
Pvolve is a science-led workout method that combines low-impact functional fitness with resistance-based equipment, she has said.
That is how she stays a reported 117lbs at 5ft5in.
The Emmy winner talked to InStyle about how she has beaten her body up over the past 15 years in order to look Hollywood perfect but it has taken a toll on her.
While talking up her collaboration with fitness brand Pvolve, she said now her mindset around health has shifted.

That means she no longer does exercises that are 'too repetitive' – like being on a StairMaster for hours. 'When you're in a mindset of, "I need to do 45 minutes of cardio or I won't get a good workout," it's daunting,' she shared with the site. 'I believed it for so long. I just burnt out and broke my body.'
Sometimes she just worked out too hard. And a therapist had to point it out. 'My physical therapist gave me a Barbie doll that's covered in Kinesio tape,' she shared.
'It's a silly mental image until you realize the purpose of all that tape is 'to show every injury I've had in the last 15 years.'

How she cultivates the right workout vibe: 'I much prefer working out with friends,' she admitted.
'Doing your own workout by yourself, meh. If you get some good music going you can have fun, but I like to be guided. It's too easy for me to do things less correctly than I should.'
Turns out she jams to hip hop during her sweat session.
'It's hard for me to choose favorites. There are so many! I'm really into Lizzo right now, I love Rihanna, of course, and I love old-school '90s hip-hop.'
The Hollywood it girl started working with the program after hurting her back two years ago.
And she claims Pvolve helps 'strengthen and restore' her body through its on-demand classes. 'As we get into our lovely older periods, we have to keep it exciting. And we have to be kinder to our bodies,' the Friends vet told People this week.
And she has told her pals to get on it. 'I like to find something that really works and then share it with my girlfriends,' Aniston noted. 'If I had known about it 20 years ago when I was breaking my body to begin with, we would've saved so much pain.'
Aniston went to Pvolve founder Rachel Katzman to talk about working together to promote the program. 'I just want more people to know about it because I think it's so good,' the actress added.

Last year Jennifer said she loves a 'cheat day' and will sip on a dirty martini cocktail when the mood takes her.
The Emmy winner is committed to a healthy and holistic lifestyle and follows a high-protein, low-carb and low-sugar diet.
Aniston will reward herself with cheat days when she wants to enjoy her favorite foods and drinks.
The 30 year anniversary of Friends is this year
Her alcoholic tipple of choice is the martini mix, which is made with gin and vermouth and garnished with an olive or a lemon twist.
A source told Us Weekly magazine: 'Jen's meals are rich in protein with a healthy amount of carbs, and she also indulges in treats and cheat days.
'If she wants to enjoy a dirty martini or tequila, she'll splurge. It's no big deal.'
When it comes to relaxing, The Morning Show star practices meditation and makes sure she gets plenty of fresh air with her pet dogs.
The source added: 'She meditates, and loves hikes with her dogs.'
Jen is said to not be worried about ageing and has no interest in cosmetic procedures and instead wants to focus on being 'healthy and happy' as she continues to grow as a woman.
The insider spilled: 'Jen feels fine about getting older. For her, it's about being healthy and happy as she can be.'
