Jennifer Aniston is changing her fitness routine to focus on low-impact strength training.

In an interview with People, the 57-year-old actress said she spent years running on treadmills and ellipticals to stay lean. Now, she relies on resistance movements that build muscle without tearing up her joints.

“Like anything, you just sort of say, ‘Well, that worked for then,’” she said. “‘But now this is what works now.’”


Rethinking Exercise and Bone Density

For years, Aniston said she avoided lifting weights after hearing the rumor that resistance training makes women look bulky.

“I used to dread it because you’d hear the word muscle training or weight training, and then you just get that in your ears, someone says to be careful, you don’t want to bulk up,” she told the outlet.

Adding weights into a weekly routine is actually one of the best things women can do for their bodies in their 50s. According to the Mayo Clinic, female bone mass peaks around age 30, and menopause naturally speeds up bone loss. Regular weight-bearing workouts help maintain bone density and protect against osteoporosis.

To build that muscle safely, she relies on Pvolve, a science-led functional fitness program that uses targeted resistance equipment to strengthen the body without putting heavy stress on joints. Aniston originally signed up as a member in 2021, then joined the company as an official partner and investor in 2023.

“I can do a 30-minute Pvolve workout and be drenched and have such incredible results without literally breaking my body,” Aniston told People in 2025.

“I used to think a workout meant you just got to sweat for an hour to 45 minutes, whether it’s running around a room, doing aerobics, or running on a treadmill — 45 minutes of cardio. Otherwise, it’s useless,” she continued. “I’m just so grateful that’s not true.”

Prioritizing Long-Term Mobility

Her ultimate motivation to stay active comes from watching her parents navigate the later stages of their lives.

“We’re all getting older, that’s inevitable,” she recalled. “But my dad and my mom were older when they were at the end of their life, but they couldn’t move.”

She added: “Who wants to have the luck of living into your 80s and 90s and not be able to get up and move?”

That perspective keeps her going. Even when her energy is low, she convinces herself to just put on her gym clothes and commit to 20 minutes.
