For a growing number of Mt. Lebanon women, the goal of exercise isn’t simply to lose weight or look better. It’s to stay strong enough to enjoy life for decades to come.

Whether the motivation is improving bone density, reducing pain, increasing energy or maintaining independence, more women are turning to strength training as they age.

At 75, Jan Littrell considers lifting weights an essential part of staying healthy.

“We can get away with not exercising and not eating the right foods when we’re younger, but not when we’re older,” Littrell said. “It’s nonnegotiable for me.”

Five years ago, Littrell began strength training at Mecka Fitness in Mt. Lebanon. She started in Fit55, a class designed for adults 55 and older, before progressing to a general group fitness class alongside members decades younger.

The supportive environment, she said, helped her become stronger and more confident.

Across Mt. Lebanon, women in their 40s, 50s and beyond are approaching fitness differently. Rather than exercising primarily to change their appearance, many are training for better balance, stronger bones, less pain, more energy and the freedom to remain active as they age.

Rachel Battis, a CrossFit coach at Mecka Fitness who leads the gym’s Women’s Strength School, said women older than 35 make up the majority of her participants.

“Most of the women who have joined my strength courses are over 35,” Battis said. “The age range has been anywhere from 22 to 75, but the majority are in their 40s and 50s.”

Sam Pitcairn, founder of Essential Strength and a personal trainer with a background in sports science and exercise physiology, has seen a significant shift in women’s approach to fitness.

“Women have stopped training for the mirror and started training for function,” Pitcairn said. “They want to feel strong, move well and slow the aging process—not just look a certain way in a photo.”

Certified fitness trainer and nutrition coach Marcey Kotar Hancock said even the language women use has evolved.

“The biggest change I’ve seen is that women are becoming less afraid of lifting heavy and taking up space in the weight room,” Hancock said. “Years ago, so many women came in saying they wanted to ‘tone,’ ‘burn calories’ or ‘get smaller.’ Now I hear more women say, ‘I want to feel strong,’ or ‘I want to protect my body.’”

For many women, that shift becomes more urgent during midlife. Pain, stiffness, fatigue, slower recovery and menopause-related changes can make everyday activities more challenging.

Dr. Kira Steele, PT, DPT, owner of Physio412 and creator of the app-based strength program Stronger With Steele, said women often seek help for back, hip, shoulder or knee pain, only to discover other underlying concerns.

“As we work together, we also uncover decreased energy, slow recovery, body image dissatisfaction and weight concerns,” Steele said. “In our 40s and 50s, we have careers, families, children and aging parents. We’re experiencing the transition through menopause while also navigating one of the busiest seasons of our lives.”

Bone health is another reason many women begin lifting weights. According to the Office on Women’s Health, osteoporosis affects one in four women age 65 and older in the United States, and some women lose as much as 25% of their bone mass during the first 10 years after menopause.

“Many of my participants start strength training because they’re concerned about bone density and osteoporosis,” Battis said. “Somewhere along the way, a doctor, a book or even social media convinced them they need to strength train as they age to protect their bones.”

Pitcairn said strength training takes advantage of the body’s natural ability to adapt.

“Bone is not a fixed structure,” he said. “It is living tissue in a constant state of remodeling. This is the single most important training window in a woman’s life, and most women miss it entirely.”

Hancock said nutrition is equally important, particularly during perimenopause and menopause.

“The basics still matter—protein, fiber, hydration, fruits, vegetables, healthy fats and eating enough overall—but women often need to become more intentional,” Hancock said.

Her advice isn’t to eat less but to fuel the body for strength, recovery and healthy aging.

“The main message I’d give women is this: As we age, nutrition shouldn’t become more restrictive; it should become more supportive,” Hancock said. “Strength training combined with proper nutrition is one of the best ways to stay strong, capable and healthy for the long term.”
