“Low impact” is one of the most misunderstood phrases in fitness for women over 50. It doesn’t mean easy. It doesn’t mean light weights. It doesn’t mean you should be holding back. What it actually means changes how you should train. and once you understand the real definition, a lot of the fear around exercise and joint pain starts to fall away.
Key Takeaways
- “Low impact” describes ground contact patterns, not how much weight you use.
- Strength training is low impact. A goblet squat with 30 lbs is lower impact than a jog.
- Walking is low impact, but it doesn’t provide enough load to maintain joint health on its own.
- Cartilage needs compressive load to stay healthy. Avoiding load makes joint pain worse over time.

What “low impact” actually means
What does “low impact” mean in exercise?
“Low impact” is a biomechanical term. It describes the forces your body experiences when it contacts the ground. In technical terms, it refers to ground reaction force. When both feet stay in contact with the ground at all times, or when the airborne phase is eliminated, the impact forces on your joints stay low. That’s the definition. It has nothing to do with how hard you’re working or how much weight you’re using.
Low impact activities include walking, swimming, cycling, strength training, using an elliptical machine, and rowing. What these have in common is that neither foot leaves the ground simultaneously, or the body is supported in water, or the movement is driven by pushing against a fixed surface rather than landing from a jump. The ground reaction force stays controlled and relatively even throughout the movement.
High impact activities include running, jumping, plyometrics, jump rope, and box jumps. In these movements, both feet leave the ground at once. When you land, your joints absorb forces that can reach two to three times your body weight in a fraction of a second. That’s what “high impact” actually means. It’s not about effort. It’s about what happens when your foot hits the ground.
Here’s where most people go wrong. The word “impact” sounds like it should relate to intensity or effort. So when a doctor or trainer says “stick to low impact,” many women hear “keep it easy, use light weights, don’t push yourself.” That interpretation leads to training that’s so gentle it can’t actually build strength or protect joints. You end up in a cycle where you’re exercising regularly but getting weaker, not stronger.
The confusion is common enough that it shapes the exercise choices of millions of women over 50. They give up strength training because it “sounds like high impact.” They walk every day but avoid the weight room. They feel like they’re doing the right thing. But they’re missing the component their joints actually need most.
Research Note
Fransen M et al. (2015) in the Cochrane Database of Systematic Reviews examined exercise for knee osteoarthritis and found that land-based exercise reduces pain and improves physical function in people with knee OA, with effects maintained regardless of the type of exercise used. This supports the view that movement and load, not avoidance of impact forces, drive joint health outcomes. What matters is that you move and load the joint progressively, not that you avoid all challenge.

After 29 years of training women full-time, the single most common thing I hear from new clients is some version of “my doctor said low impact, so I stopped lifting weights.” I have to explain that strength training is low impact. The weight room is exactly where they should be.
Low impact does NOT mean low load
Can you lift heavy weights and still do low impact exercise?
Yes. Heavy strength training is low impact. When you perform a deadlift, squat, press, or row, both feet stay planted on the ground throughout the movement. There’s no airborne phase, no hard landing, no rapid spike in ground reaction force. The compressive load you place on your joints is controlled, gradual, and sustained. That’s the opposite of what happens during running or jumping.
To make this concrete: a goblet squat with 30 pounds is lower impact than a light jog around the block. The jog sends repeated ground-strike forces through your knees and hips hundreds of times over the course of a mile. The squat asks your joints to handle a steady compressive load through a controlled range of motion, with both feet on the floor the entire time. If you have knee concerns, the squat is likely the safer choice, not the jog.
Your cartilage actually needs compressive load to stay healthy. Cartilage has no blood supply of its own. It gets its nutrients through a process called synovial fluid exchange, which is driven by compression and decompression. When you load a joint under resistance, you’re pumping nutrients in and waste products out. When you avoid load entirely, that exchange slows down. The cartilage begins to degrade from underuse, not from overuse.
The LIFTMOR trial, published by Watson SL and colleagues in the Journal of Bone and Mineral Research in 2019, is especially relevant here. This was an eight-month randomized controlled trial involving postmenopausal women with low bone mass. Participants performed supervised heavy deadlifts and overhead presses. The result: significant improvements in bone density, with no greater fracture or injury risk compared to a lighter-resistance control group. Lifting heavy didn’t hurt these women. It helped them.
What this means for you is that if you’ve been avoiding heavier weights to “protect” your joints, you may have been doing the opposite of what your joints need. Avoiding load removes the stimulus that maintains cartilage health and builds the muscle that cushions and stabilizes joints. The goal isn’t to go light. The goal is to find the right load for where you are right now, and then build from there progressively.
Research Note
Watson SL et al. (2019), Journal of Bone and Mineral Research, reported that postmenopausal women with low bone mass who performed eight months of supervised high-intensity resistance training, including heavy deadlifts and overhead presses, showed significant improvements in femoral neck bone density with no increased fracture or adverse event rate compared to controls. This directly contradicts the assumption that lifting heavy is inherently more dangerous for women with joint or bone concerns.

I see women come in every year who’ve been told to “go light” for joint safety, and what I find consistently is that their joints feel worse than they did before they started being careful. Underloading is its own injury mechanism. The joints need to be worked to stay healthy.
Why “low impact only” often makes joint pain worse
Can avoiding high impact exercise make joint pain worse?
It can, and for a specific reason. Your cartilage has no direct blood supply. Unlike muscle, which gets its nutrients through the bloodstream, cartilage depends on synovial fluid movement driven by mechanical compression. When you load a joint and then release that load, you push fluid in and out of the cartilage tissue. That fluid exchange is how cartilage gets its oxygen and nutrients. When you avoid loading the joint, that process slows to a crawl.
Buckwalter JA and Martin JA, writing in the journal Injury in 2006, described how articular cartilage responds to mechanical loading. Their work established that moderate cyclical compression maintains cartilage health, while prolonged immobilization or chronic underloading leads to cartilage degradation. The tissue breaks down not because it was worked too hard, but because it wasn’t worked enough. This is the paradox that most “gentle exercise” advice misses entirely.
There’s a second problem that runs alongside the cartilage issue. When you train with weights that are too light to create a meaningful training stimulus, your muscles don’t grow or maintain their strength. They get smaller and weaker over time. That matters enormously for joint health, because muscle is the primary shock absorber and stabilizer for your joints. The quadriceps protect your knees. The glutes and hip abductors protect your hips. When those muscles weaken, the joint itself takes more stress from every movement you do, even gentle ones.
Women who are told to “take it easy” often end up in a pattern where they do enough gentle exercise to feel like they’re being active, but not enough to maintain the strength their joints need. Over months and years, the muscle atrophies, the cartilage degrades from underloading, and the joint pain gets worse. They believe the exercise is making them worse. In many cases, it’s not the exercise. It’s the insufficient load.
Gentle movement does help. Walking, light stretching, gentle range-of-motion work all have value. But they can’t do the job that progressive resistance training does. If gentle movement is all you do, you get some of the benefit of movement without the benefit of load. For joint health, you need both. The goal is low impact combined with appropriate and progressing load. That’s the combination that actually protects your joints over the long term.
Research Note
Buckwalter JA and Martin JA (2006), writing in Injury, demonstrated that articular cartilage requires moderate mechanical loading to maintain its structural integrity, and that underloading leads to cartilage matrix degradation comparable to what’s seen with excessive loading. This means the protective instinct to avoid loading painful joints can accelerate the very degeneration it’s meant to prevent.
Expert Tip — Stephen Holt, CSCS
The women who come to me after years of “being careful” are often in worse shape joint-wise than those who were more active. They’ve been protecting their joints by avoiding the very thing their joints needed. It takes time to reverse, but it does reverse when they start loading progressively.
The right way to use low impact training
What is the best low impact exercise program for women over 50 with joint pain?
The answer is low impact combined with progressive load. Not low impact and low load. Not low impact and easy. Low impact as your movement category, with progressively increasing resistance as your training principle. Those two things together create conditions where your joints get the movement and the mechanical stimulus they need without the jarring forces of running and jumping.
Starting light is fine if that’s where you are. If you’ve been sedentary, if you’re returning from an injury, or if you’re just getting started with resistance training, beginning with bodyweight or light resistance makes sense. But the plan has to include progression. Each week or two, you increase the load, the volume, or the difficulty. Without that progression, you’re not giving your muscles or your joints a reason to adapt and get stronger.
What does “appropriately challenging” look like in practice? It means the last two or three reps of a set feel genuinely hard. Not painful. Not dangerous. But hard enough that you’re working to complete them. If every set feels easy, the weight isn’t doing its job. If you finish a workout and feel like you could’ve done twice as much without any effort, you’re not training in the zone where adaptation happens.
At 29 Again Fitness, the approach is two strength sessions per week built around compound movements, combined with walking or swimming between sessions. The compound movements, things like squats, deadlifts, presses, and rows, train multiple muscle groups at once and place the kind of full-body compressive load that supports bone density, cartilage health, and muscle mass simultaneously. The walking or swimming fills in movement without adding significant loading stress.
Two sessions a week is enough to drive meaningful adaptation in women over 50 when those sessions are structured well and progressively loaded. You don’t need to train every day. You need to train smart, consistently, and with enough challenge to give your body a reason to get stronger. That’s how you build the muscle that actually protects your joints through every other activity you do.
Expert Tip — Stephen Holt, CSCS
Two sessions a week doesn’t sound like much, but when each session is progressively loaded and built around compound movements, I see women make consistent, measurable strength gains that directly translate to less joint pain and more confidence moving through daily life. The dose is right when you’re adding load over time, not when you feel maximally tired.
When high impact training is appropriate — and when it’s not
Is high impact exercise ever good for women over 50?
There’s a legitimate case for some high impact loading in specific circumstances. Impact forces stimulate osteoblast activity, which is the process by which your body builds new bone. Research has shown that activities involving ground-strike forces can contribute to bone density in a way that non-impact activities don’t fully replicate. For this reason, some clinicians recommend incorporating heel drops, small hops, or brief jumping progressions for women managing osteopenia or early osteoporosis.
The women most likely to benefit from this type of work are those who have osteopenia or mild osteoporosis, no acute joint problems, stable joint health, and physician clearance to add impact loading. If your bone density is low and your joints are otherwise healthy, a carefully graduated introduction to impact loading may be worth discussing with your doctor or physical therapist.
There are situations where high impact exercise is clearly not appropriate. Severe osteoarthritis with significant joint damage, post-surgical joints that haven’t fully healed, acute joint inflammation, and significant pain with weight-bearing activities are all contraindications. In these cases, the impact forces from running or jumping exceed what the joint can safely handle, and the risk of harm outweighs any potential benefit. Low impact training remains the right choice here, and it should stay that way until and unless the joint status changes.
If working toward some impact loading is a goal, the progression should be gradual. Start with heel raises to load the lower leg and stimulate some impact adaptation. Move to small, controlled hops once that’s comfortable. Increase the height and volume of jumps slowly over weeks and months. Your connective tissue, bone, and cartilage adapt more slowly than your muscles do, so rushing this progression is where injuries tend to happen.
For most women over 50 with joint concerns, though, high impact exercise isn’t necessary to get strong, maintain bone density, and protect your joints. Progressive strength training, done consistently with appropriate load, provides most of the joint-protective and bone-building benefit you need. You don’t have to run or jump to get strong. The low impact path, done right, gets you where you need to go.
Quiz: How Are You Training Your Joints?
Five questions. Find out if your current approach is actually protecting your joints.
1. How would you describe your current exercise routine?
2. What do you avoid because of joint concerns?
3. How do you currently feel about lifting heavier weights?
4. When a trainer or doctor says “low impact,” what do you assume they mean?
5. How does your joint pain respond to exercise?
Is strength training considered low impact exercise?
Yes. Strength training is low impact because both feet stay on the ground throughout most exercises. A deadlift, squat, or press creates compressive load on your joints, but it doesn't create the impact forces that running and jumping do. That's why strength training is often safer for joint health than cardio people consider "gentle." A jog sends repeated ground-strike forces through your knees hundreds of times per mile. A squat doesn't.
What does low impact exercise mean if I have bad joints?
Low impact means the exercise doesn't create the repeated ground-strike forces that running and jumping do. It doesn't mean light or easy. Swimming, cycling, strength training, and walking are all low impact. For bad joints, the key is combining low impact movement with enough load to maintain the muscle and cartilage health that protect those joints. Avoiding load while staying low impact gets you only half the benefit you need.
Can I lift heavy weights if I have joint pain?
In most cases, yes. The LIFTMOR trial found no greater injury risk with heavy compound lifts compared to lighter alternatives in women with compromised bone density. The key is progressive loading with good form, starting at a weight that's "appropriately challenging" and building systematically. Most joint pain responds better to appropriate loading than to rest. If you have a specific diagnosed joint condition, check with your physician before significantly increasing your training load.
Is walking enough exercise for women over 50 with joint pain?
Walking is a great start, and it's better than nothing. But it doesn't provide enough load to maintain muscle mass or slow cartilage degradation. Women over 50 need progressive resistance training to maintain the strength that protects joints. Two sessions a week of compound strength work, combined with walking, gives you both the movement benefit and the load your joints need. Walking alone doesn't create enough of a stimulus to prevent the muscle loss that accelerates joint problems.
What's the difference between low impact and low intensity?
They're completely different things. Low impact describes the type of force your body experiences during exercise. No airborne phase, no hard ground strikes. Low intensity describes how hard you're working. You can do a low impact workout at high intensity. Heavy strength training is low impact and can be very high intensity. Confusing the two leads women to train with weights that are too light to maintain muscle or protect joints. Your aim is low impact and high enough intensity to drive real adaptation.
