If you’ve scrolled FitTok lately—or simply walked into a gym—you’ve probably noticed a change. Where cardio once dominated the conversation, strength training now takes center stage for people of every age and gender.
Denise Chakoian, a certified fitness trainer and owner of Core Cycle and Fitness LaGree, calls strength work essential for anyone over 50.
“Once you hit 50, the game changes,” she says. “Your body starts moving against you in ways you don’t always feel until the damage is done. I tell every client over 50 that strength training isn’t optional—it’s the closest thing we have to a fountain of youth.”
Amanda Dvorak, CPT, a certified personal trainer with Garage Gym Reviews, shares that view.
“Adults naturally lose muscle mass with age, a process called sarcopenia, and bone density declines as well,” Dvorak says. “This raises the risk of frailty, falls, fractures and loss of independence.”
She adds that strength training stimulates muscle‑protein synthesis, boosting muscle mass, bone density and stability. It also improves metabolic health, lowering the odds of chronic conditions that become more common after 50, such as heart disease and type 2 diabetes.
“Perhaps the most overlooked benefit is functional independence,” Dvorak continues. “Being able to carry groceries, rise from the floor, climb stairs and move comfortably depends on strength and mobility—both of which are enhanced by resistance training.”
The question remains: how many minutes of strength work do adults over 50 actually need? Chakoian and Dvorak offer their take.
### How many minutes weekly?
“For most relatively healthy people over 50 who aren’t currently lifting weights regularly, I recommend two to three strength‑training sessions per week, totaling roughly 90 to 150 minutes,” Chakoian says. “That’s enough to provoke a meaningful stimulus for muscular strength, hypertrophy, bone density and metabolic health, but it’s not so much that you overtax a body that simply doesn’t recover like it did at 30.”
Dvorak suggests a slightly lower baseline: at least 60 minutes of strength training per week, split into two 30‑minute sessions for those over 50.
Part of the reason the two trainers don’t give an identical prescription is the lack of universal guidelines. The American Heart Association advises 150 minutes of moderate‑intensity or 75 minutes of vigorous‑intensity cardio weekly, yet its same statement only says to add strength training twice a week without specifying a minimum or maximum. The Centers for Disease Control and Prevention tells adults 18 and older to get “at least two days a week of muscle‑strengthening activities that work all major muscle groups.”
Dvorak clarifies that the major muscle groups are the legs, hips, back, abdomen, chest, shoulders and arms.
### Factors to consider
Pinpointing an exact amount of strength training is tricky because variables such as experience, health status, current strength and the load you use all play a role.
Chakoian offers these practical pointers:
- Beginners or those returning after a long break, injury or health issue should start with 20 to 30 minutes twice a week. “I’ve seen far too many well‑intentioned people dive in headfirst, crush themselves during their first few workouts, and end up injured or so sore they never return,” she says.
- Individuals with chronic conditions like arthritis, heart disease or osteoporosis should do zero strength training unless cleared by a medical professional.
- Those with chronic conditions who are cleared can begin modestly, sometimes with just 15 to 20 minutes of strength work per week.
- Seasoned athletes aged 50 and older who have lifted for years may handle 45 to 60 minutes of strength training three times weekly.
Intensity—defined by Dvorak as the weight used relative to your strength—also influences total session time, though not in the way many assume.
“If you’re lifting very heavy weights compared to your strength level, you’ll need more rest—two to five minutes—between sets to fully recover and get the most out of the next set,” she explains. “That can increase the total time spent in the gym, but even though a lot of that time is resting, it remains one of the most effective ways to build strength.”
Conversely, performing many repetitions with light weights and short rests can make a workout shorter, but Dvorak notes that approach isn’t optimal for developing raw strength.
### Structuring a workout at 50‑plus
What does an effective strength session look like for someone over 50? Dvorak advises logging at least 60 minutes of strength work each week, or two 30‑minute sessions, and using that time wisely:
- Perform a minimum of three sets per fundamental movement pattern (squat, hinge, push, pull, carry) each session. “In practice, that looks like three sets of five different exercises per session, or 15 total sets per session,” Dvorak says.
- Aim for a rating of perceived exertion (RPE) of 7 out of 10. She suggests thinking of RPE as “reps in reserve.” “A 7 out of 10 RPE equals three reps in reserve (RiR); at the end of the set you should feel that you only had three reps ‘left in the tank,’” she explains.
- Adjust rep targets based on the weight you’re using. “If you have access to relatively heavy weights for you, you can achieve this with fewer reps,” Dvorak states. “If you’re using very light weights, you may need to do 12 to 15 or more reps per set.”
- Keep reps per set at 15 or fewer when you have appropriate loads. “That number is plenty if you have the right weights,” Dvorak notes. “Otherwise you turn it into more of a cardio workout versus a musculoskeletal one, which diminishes the benefits of strength exercises.”
She adds that the exact rep count you complete matters less than hitting that RPE of 7 out of 10, so focus on achieving that perceived effort.
