Exercises that build bone density in the spine
The spine is one of the sites a DEXA scan checks, and vertebral fractures are among the most common fractures linked to low bone density. If your scan mentioned your lumbar spine, it is natural to wonder what you can actually do about it.
Here is what the research suggests about training for a stronger spine, and which movements to be more careful with.
Quick answer
Bone responds to load, so exercises that load the spine through its length and progress over time are a common focus of bone-focused programs: squats, deadlifts and other hip hinges, overhead presses, and loaded carries. Strengthening the muscles along your back with extensor exercises also supports spine health. If you have osteopenia or osteoporosis, guidance commonly advises caution with loaded forward bending and forceful twisting. A structured, progressive plan like StrongEra helps you build that load gradually.
What the research shows
In the LIFTMOR trial (Watson et al., 2018), 101 postmenopausal women with low bone mass were randomized to either 8 months of twice weekly, supervised high-intensity resistance and impact training or a low-intensity home program. The high-intensity group improved lumbar spine bone density by about 2.9 percent on average, while the home group lost about 1.2 percent. The training was closely supervised, with only one minor adverse event reported.
A separate Mayo Clinic study (Sinaki et al., 2002) followed 50 postmenopausal women for 10 years in total, starting with a 2 year program of progressive back-strengthening exercises. At the 10 year mark, 8 years after the program ended, the exercise group had fewer vertebral compression fractures than the control group (1.6 percent of vertebrae examined versus 4.3 percent) and still had stronger back muscles.
Both studies were small and used specific programs. LIFTMOR combined heavy lifting with impact work under close supervision, so it does not show that any single exercise below works on its own, or that an unsupervised routine will give the same results. Treat the research as a reason for optimism rather than a guarantee. LIFTMOR and other studies on strength training and bone health are listed on our research and resources page.
Exercises that load the spine
These are movements commonly used in bone-focused strength programs because they load the spine through its length. They are not a substitute for the supervised programs studied above, so if you have low bone density, ask a doctor or physiotherapist which suit you.
Squats. Whether you hold a weight at your chest or on your back, squats load the spine and hips together, the two sites DEXA scans usually focus on.
Deadlifts and hip hinges. Deadlifts, Romanian deadlifts, and other hinges load the spine while training the back of the body. Keep your spine neutral and learn the pattern with light weight first.
Overhead presses. Pressing a weight overhead while standing loads the spine from above and trains the upper back and shoulders.
Loaded carries. Walking while holding weights at your sides, or one weight on one side, asks your spine and trunk to stay tall under load.
The common thread is progression. Bone adapts to loads it is not used to, so gradually adding weight or difficulty over months matters more than picking the perfect exercise. We cover how in what is progressive overload, and how to start weight lifting for bone density has a full beginner plan.
Back extensor exercises
The muscles running along your spine help hold you upright and share the load your vertebrae carry. Exercises that strengthen them include prone back extensions (lifting your chest slightly while lying face down), bird dogs, and rows with a tall, supported spine.
These are usually low-load movements, so they can suit people who are building up to heavier lifting. Stronger back muscles also support posture, which many women care about as they get older.
Movements to be careful with
If you have osteopenia or osteoporosis, guidance commonly advises caution with two kinds of movement, because they put more stress on the front of the vertebrae:
- Loaded forward bending of the spine, such as sit-ups, crunches, and toe touches.
- Forceful or loaded twisting, especially combined with bending.
This does not mean you need to avoid movement. It means choosing exercises that keep your spine long and neutral under load. If you have had a vertebral fracture, get guidance from your doctor or a physiotherapist before loading your spine.
Takeaway
The spine responds to training like the rest of your skeleton: it needs load that gradually increases. Squats, hinges, overhead presses, and carries load it directly, and back extensor work strengthens the muscles that support it. Be careful with loaded bending and twisting, progress slowly, and give it months rather than weeks.

Frequently asked questions
What exercises increase bone density in the spine?
Bone-focused strength programs commonly use exercises that load the spine through its length, such as squats, deadlifts and other hip hinges, overhead presses, and loaded carries. Research on supervised programs is encouraging, but it does not show that any single exercise works on its own. Back extensor exercises that strengthen the muscles along the spine also support spine health. Progression over time matters more than any single exercise.
Can you increase bone density in the lumbar spine?
Research suggests it is possible. In the LIFTMOR trial, postmenopausal women with low bone mass who did 8 months of supervised high-intensity resistance and impact training improved lumbar spine bone density by about 2.9 percent on average, while a low-intensity home exercise group lost about 1.2 percent.
Why do back extensor exercises matter for the spine?
The muscles along your spine help support posture and share the load your vertebrae carry. A Mayo Clinic study found that postmenopausal women who did 2 years of progressive back-strengthening exercises had fewer vertebral compression fractures at a 10 year follow-up than a control group.
What exercises should I be careful with if I have osteopenia or osteoporosis?
Guidance commonly advises caution with loaded forward bending of the spine, such as sit-ups and toe touches, and with forceful twisting. Everyone is different, so check with your doctor or a physiotherapist about what is appropriate for you, especially if you have had a vertebral fracture.
