Resistance training
Also called: strength training, weight lifting
What it means
Resistance training is exercise where your muscles work against weight or resistance, like squats, deadlifts, or bodyweight moves, which pulls on bones and helps support muscle strength and balance.
Strong muscles pull on your bones and keep you steady on your feet, and since most fractures after 50 start with a fall, that protection matters a great deal.
Resistance training means working your muscles against some kind of resistance — weights, machines, bands, or even just your own body weight. When a muscle contracts forcefully, it pulls on the bone where it attaches, and that pulling force is one of the signals that tells bone it needs to stay strong. Good bone-friendly moves include squats, lunges, deadlifts, overhead presses, and rows, which load the hips, spine, shoulders, and wrists. Bodyweight exercises like pushups and step-ups count too.
You don't need to lift heavy to benefit — doing it consistently, about 2-3 sessions a week covering the major muscle groups, is what matters. Beyond any direct effect on bone, resistance training builds and preserves muscle, improves balance, coordination, and reaction time, and helps you get up off the floor more easily. That matters a lot, because most fractures after age 50 start with a fall, and this protective effect happens largely separate from bone density itself.
As people age, muscle naturally declines, a condition called sarcopenia, and less muscle means less force reaching the skeleton, which means less stimulus for bone. Keeping your muscles strong helps keep that stimulus going, which is one reason strength training is worth doing even though it rarely builds much bone on its own. It also fits well alongside other habits — adequate protein, vitamin C for collagen, and calcium and vitamin D — all of which support bone and muscle together, including during times like rapid weight loss when muscle and bone can both be affected.

Questions people ask about this
Your doctor's advice to lift weights is genuinely good advice — keep doing it. Resistance training builds muscle, improves balance and coordination, and lowers your risk of falling, which matters enormously since most fractures after 50 start with a fall. The honest nuance is that it's one important piece, not the whole picture, when it comes to directly challenging bone.
Read the full answer →The main differences are how the force is applied and how often you do it. Instead of lifting external weights, you push against a device that doesn't move, so your own body determines how much force you generate — and sessions are brief (about 10 minutes) and only once a week, rather than the more frequent sessions typical of gym-based weight training.
Read the full answer →Between sessions, focus on four things: weight-bearing activity most days, resistance training a couple times a week, daily balance practice, and at least one rest day. This daily movement doesn't replace what happens during your session, but it supports your muscles, circulation, and balance, which all work alongside your bones.
Read the full answer →Yes — resistance training is one of the best things you can do for your bones, along with your muscles, balance and overall function. It won't cure osteoporosis, but research shows it can help hold bone density steady, and well-supervised heavy lifting programs have shown real gains at the spine in some trials.
Read the full answer →Yes — for most people with osteoporosis, exercise is not just safe but genuinely beneficial. Resistance and weight-bearing exercise help maintain bone density and strongly reduce fall risk by improving muscle, balance, and coordination — and since most fractures after 50 start with a fall, that protection matters a great deal. That said, your own situation (fracture history, balance, other health conditions) should guide exactly what type and intensity is right for you, so it's worth discussing specifics with your doctor.
