An earlier post here compared weight-bearing exercise and resistance training and concluded, correctly, that you need both. What that post did not answer is what changes once you have a fracture behind you. That is a different question, and it is the one readers keep asking me.
I ask it too. I have had multiple vertebral compression fractures, and I remember standing in my kitchen a few weeks after the first one, holding a two-pound dumbbell, not sure whether picking it up was going to help my bones or break another one. Both were possible. What tips the balance is the modifications you make and the person guiding you through them.
Get Cleared Before You Do Anything
Before you add or resume any exercise after a fracture, get medical clearance. This is not a formality. A fresh vertebral compression fracture is still remodeling for weeks to months, and the wrong loading pattern in that window can extend the injury or set off a new one. A hip fracture is a surgical injury with weight-bearing restrictions that depend on the specific repair. Your surgeon or your primary doctor is the person who tells you when it is safe to progress and what is off limits until then.
Beyond the first clearance, ask for a referral to a physical therapist who specifically works with osteoporosis patients. The Too Fit To Fracture consensus panel recommends this for anyone at high fracture risk who is starting a new program, and I would extend that to at least one session for anyone with a fracture history, even if you have been exercising for years. Form is what makes these programs safe. A trained set of eyes on your squat, your hinge, and your posture during a loaded carry is worth more than any article I can write.
When Is It Safe to Start Again
There is no single number that applies to every fracture. Doctors and physical therapists give ranges, and they let your healing and your pain, not the calendar, tell them when to move you along. Here is a reasonable frame, and all of it assumes your doctor has already given you the go-ahead.
Hip fracture. Recovery starts almost right away. The day after surgery, most people are helped out of bed and taught how to take their first steps, usually with a walker. This early movement is not optional. It protects against the fast loss of muscle that turns a temporary weakness into a lasting one. Your surgeon may give you hip precautions, meaning specific movements to avoid, and those usually stay in place for about six to twelve weeks. Physical therapy for strength and balance starts in the hospital and continues for months. Getting back to comfortable walking around the neighborhood, climbing stairs, and running your own errands is a project of several months, not weeks.
Movement is one half of that project. The other half is food, and specifically protein. Muscle and healing bone are both mostly protein, and appetite tends to drop right when the body needs more of it. The companion post on protein after a fracture covers what to eat during recovery, including easy options when cooking is not the answer.
Vertebral compression fracture. This one is harder to time because there is no surgery to count from. Cleveland Clinic notes that the sharp pain usually starts easing around four weeks, that most fractures heal in about eight to twelve weeks, and that more severe ones can take a few months. A review in American Family Physician reports that most of the pain relief in people doing well happens by three months, and that people who feel much better at three weeks tend to hold on to those gains. Gentle standing and short walks are often possible sooner, sometimes within the first few days if your pain is manageable and your doctor agrees. Lifting weights and any real resistance training usually waits until the fracture has healed. In practice, that is often eight to twelve weeks at the earliest, and longer if the fracture is more severe or if you have had more than one.
Two things move that timeline in either direction. The first is how bad the fracture is. A small, stable break heals faster than a bigger one or several fractures at once, and the safe restart window pushes out accordingly. The second is how well you are healing, which your doctor is watching through your pain, your function, and sometimes a follow-up x-ray. If your pain is not settling the way it should, or a new image shows the fracture is still active, the whole schedule waits.
One more thing worth saying plainly. The modifications will change over time, but there will always be some. In the first weeks after a fracture they are strict, because the bone is still healing. As you get stronger, you will safely add back movements and weights that were off the table early on. But some rules stay for good. Once you have had a fragility fracture, being careful about how you load your spine, how much impact you take on, and how quickly you add weight is part of protecting the bones you have. That is not a punishment. It is how you keep the next one from happening.
What Actually Changes After a Vertebral Fracture
The single most important modification is this. Do not load your spine while it is bent forward. That means no sit-ups, no crunches, no weighted toe-touches, no rowing machines that round your upper back, and no reaching down to pick up a heavy grocery bag by curling your back over. Repeated deep forward bending is the movement pattern most closely linked to vertebral wedging in bones that already have low density, and the UK Strong, Steady and Straight consensus tells clinicians to avoid or change it during any activity, including yoga and Pilates.
Twisting and side-bending are two more that deserve attention. The same consensus says that gentle rotation and side-bending are fine as long as they are done smoothly and within a comfortable range. What causes trouble is fast, forceful twisting, especially with weight in your hands. Case reports describe vertebral fractures happening mid-golf-swing and even during a hard roll from lying face down to face up. The takeaway is not to avoid turning your body. It is to slow the movement down, keep it small, and never combine a twist with a heavy load or a sudden change of direction. When you reach for something behind you, turn your feet first so your spine does not have to.
Impact needs to come down too. That same consensus recommends that people with vertebral fractures or multiple low-trauma fractures cap impact at about brisk walking, roughly 150 minutes across the week, until a physiotherapist personally clears them for more. That is a precaution, not a permanent ceiling. Over time, and with supervision, you can gradually reintroduce more impact if your bones and your tolerance allow. But you start below the line, not above it.
What you should add is back-extensor strengthening. This is where the evidence is strongest and where I have the most personal skin in the game. Mehrsheed Sinaki's ten-year follow-up study at Mayo found that postmenopausal women who did a two-year back extensor program had a vertebral fracture rate of 1.6 percent, compared with 4.3 percent in the control group. The relative risk of a new compression fracture was 2.7 times higher in the women who did not strengthen those muscles, and the difference was still there eight years after they stopped exercising. Those muscles pull the spine into extension, protect the vertebrae from wedging forward, and improve posture. If you do nothing else new, do this.
The extension work does not have to be dramatic. Prone lifts, meaning lying face down on the floor and gently lifting your chest a few inches, are one option. Seated rows with a resistance band are another. And so are standing wall angels, an exercise where you stand with your back and arms against a wall and slowly slide your arms up and down in the shape of a snow angel while keeping contact with the wall. The Strong, Steady and Straight consensus suggests holding each rep for three to five seconds and repeating three to five times, daily, for pain and posture after a fracture. Small doses, done consistently, do the work.
What Actually Changes After a Hip Fracture
A hip fracture is a different kind of recovery. The 2021 clinical practice guideline in JOSPT is unambiguous. Structured strength training for the legs, balance training, and functional mobility work are all recommended, and physical therapy should start early, often the day after surgery. Getting up and moving in that first week is not optional. It protects against the loss of muscle mass that turns a temporary weakness into a permanent one.
After the acute phase, the exercises that matter most are the ones that build the muscles around the hip and improve your ability to catch yourself. Sit-to-stand practice from a firm chair. Standing hip abduction with a light band. Bridges. Step-ups onto a low step, with a rail. Progressive weighted squats and deadlifts, taught by a physical therapist first and with light loads, become appropriate later, and they matter because loading through the hip is what maintains density at the fracture site itself.
Balance is not a nice-to-have here. It is the reason you had the fracture, in most cases, and it is the reason you are at higher risk of the next one. Aim for the target the Too Fit To Fracture panel recommends: roughly 15 to 20 minutes a day, or about two hours across the week, of balance work. That can be tandem standing while you brush your teeth, single-leg stands at the kitchen counter, or a tai chi class. It does not have to look like exercise. It has to be done.
The Muscles That Protect the Fracture Sites
Two anatomies, two protective muscle groups.
For the spine, prioritize the back extensors and the deep core. The back extensors are the long strap-like muscles running along either side of your spine that hold you upright and resist the forward wedging force that causes compression fractures. The deep core is the layer of muscle underneath the six-pack, wrapping around your midsection like a corset, along with the pelvic floor. Together they stabilize your trunk without asking your spine to curl forward. Slow belly breathing, wall angels, prone lifts, band rows, and gentle hip hinges taught with a neutral spine all belong in this group.
For the hip, prioritize the glutes, quadriceps, and hip abductors. The gluteus medius on the side of the hip stabilizes your pelvis when you stand on one leg, which is basically what walking is. Weak abductors are one of the strongest predictors of falling sideways, and sideways is the direction that breaks hips. Side-lying leg lifts, banded lateral walks, single-leg bridges, and step-ups all target this group. Quadriceps strength is what gets you up out of a chair without using your hands, which is a functional test worth doing at home.
Age and Prior Exercise History Change the Dial
How much you can do, and how quickly you can progress, depends on more than the fracture itself.
If you were athletic before your fracture, you have muscle memory, coordination, and often better bone quality outside the fracture site than the average person your age. You will progress faster and can usually tolerate more load sooner, still with supervision, still with the flexion restrictions. If you were sedentary, everything starts smaller. Chair squats before free-standing squats. Wall push-ups before floor push-ups. Ten-minute walks broken into two five-minute pieces if needed. The Too Fit To Fracture panel specifically notes that people who are new to resistance training should start at lower intensity even without a fracture history, and that applies doubly with one.
Age matters in the same direction. In your late fifties or sixties, you have more headroom to build than most people assume. The LIFTMOR trial ran postmenopausal women with an average age of 65 through supervised high-intensity resistance and impact training twice a week for eight months, and lumbar spine BMD went up 2.9 percent while the low-intensity control group lost 1.2 percent. A follow-up analysis found no new vertebral fractures in the training group and an improvement in thoracic kyphosis. The catch is in the word supervised. Every participant was trained by an exercise scientist who watched every rep. In your seventies and beyond, the same principles hold, but the ramp is longer and balance work carries more weight in the mix. The Strong, Steady and Straight consensus notes that higher dose and longer intervention were associated with greater change, especially in people over 70. It just takes more time to accumulate.
Safety Modifications Worth Making Once and Keeping
Some of these are technique, some are equipment, some are environment. All of them reduce your risk on the days you do not feel like paying attention.
- Move slowly through transitions. Rapid twisting to get up from the floor or into the car is one of the mechanisms behind fractures that happen out of nowhere, according to the Too Fit To Fracture panel. When you need to turn, step your feet around rather than wrenching your spine.
- Hinge from the hips with a neutral spine when you pick anything up. Bend your knees, keep your chest tall, and let your hips do the work.
- Skip the abdominal-crunch machine. Substitute planks or bird-dogs, taught by your PT first so the form is right.
- Be careful with resistance machines that require you to fold forward to get into position. If you cannot get set up and out again with a neutral spine, use a different exercise.
- Do balance work near a countertop or a sturdy chair back, not out in the middle of the room, and wear flat, grippy shoes.
- Never do a new movement heavy. Learn it light. Add load once the pattern is automatic.
- Warm up. Cold muscles around a healed fracture are less forgiving than they used to be.
What This Looks Like in Practice
My own week, after clearance and after several PT sessions, looks something like this. Two supervised resistance sessions of about 30 to 45 minutes, focused on hip hinges taught with a neutral spine, back extensor work, glute and quadriceps loading, and pressing movements for the upper body. A daily walk of 20 to 30 minutes, brisk enough to count as impact but nowhere near jogging. Balance work built into ordinary tasks, tandem stance at the sink, single-leg stand while the coffee brews. Extension holds on the floor before bed. Nothing exotic. Nothing heroic. Nothing my PT has not watched me do first.
Exercise after a fracture is not the same as exercise before one. What it can be is more precise, more protective, and, done right, more effective at the sites that matter most. Get the clearance. See the PT at least once. Modify the two or three things that need to change. Then keep going.
