Preventing osteoporosis means slowing down age-related bone loss and maintaining or increasing bone density. The most effective measures are regular strength training with progressive overload and a bone-healthy lifestyle. Which exercises are effective, what nutrition should provide, and what matters during menopause – the most important answers at a glance.
What Is Osteoporosis and How Does Bone Loss Develop?
Osteoporosis is a disease of the skeletal system in which bones lose density and stability. They become more porous, fragile, and break more easily. Typical fractures occur in the vertebrae, wrists, and femoral neck, often after minor falls or everyday movements.
Bones are continuously rebuilt throughout life. Specialized cells break down old material while others build new tissue. Until around the age of 30, bone formation outweighs bone breakdown. During this phase, the body reaches its maximum bone mass, known as “peak bone mass.” After that, the balance reverses. Each year, slightly more bone substance is broken down than rebuilt.
According to the Swiss Association Against Osteoporosis (SVGO/ASCO), around one in three women and one in five men over the age of 50 in Switzerland are affected by osteoporosis. (1) Age-related bone loss does not happen overnight – it develops gradually and silently. It cannot be felt. Pain usually appears only once bone density has significantly decreased or a fracture occurs. Experts refer to the preliminary stage as osteopenia when bone density values fall below the normal range. If they continue to decline, the diagnosis becomes osteoporosis.

Factors That Promote Osteoporosis
- Lack of exercise is one of the most important factors. Without mechanical stress, little new bone mass can be formed.
- Low calcium and vitamin D intake
- Smoking
- Excessive alcohol consumption
- Hormonal changes, especially during menopause when declining estrogen levels accelerate bone loss.
Lifestyle factors such as exercise, nutrition, smoking, and sunlight exposure influence 20 to 40 percent of maximum bone density, according to a systematic review by the National Osteoporosis Foundation. (2) This is exactly where osteoporosis prevention begins.
How Strength Training Can Increase Bone Density
Bones respond to mechanical load. Regularly lifting weights sends a stimulus to the skeleton. In response, bones store more minerals and become denser. This principle is described by Harold Frost’s mechanostat theory. Without sufficient stimulus, bone tissue switches into conservation mode.
The load itself is crucial. Walking or gentle yoga alone is often not enough to increase bone density and prevent osteoporosis. Real effort is required. Muscles need to pull, and bones need to feel challenged. Strength training with squats, deadlifts, or shoulder presses can provide exactly that.
There is also a second benefit. Stronger muscles stabilize joints, improve balance, and reduce the risk of falls. Strength training therefore works in two ways: it builds muscle and strengthens bones.
Which Exercises Strengthen Bones?
To prevent osteoporosis, the focus should primarily be on resistance and impact training. In practice, this means full-body training with large compound exercises. Squats, deadlifts, shoulder presses, and rowing movements engage multiple muscle groups simultaneously and transmit high loads to critical skeletal regions such as the hips and spine.
A barbell provides the most solid foundation because the weight can be progressively increased in small increments.

A stable weight bench expands the exercise selection with bench presses and seated shoulder presses. Dumbbells are ideal for functional training and additionally improve balance and coordination.
Are machines or free weights better for strength training? Both have advantages. A multi-gym station guides movement patterns safely, which can be helpful when returning to training after a long break. Free weights simultaneously train the deep stabilizing muscles and improve core stability. In most cases, a combination of both works best. Two to three training sessions per week are sufficient, provided the load is increased progressively over time.
Which Sports Should Be Avoided With Osteoporosis?
Very few activities are completely forbidden. However, certain movement patterns can place harmful stress on weakened bones. Anyone diagnosed with osteoporosis or who has already suffered fractures should choose sports carefully.
Sports involving sudden twisting movements can be problematic. Tennis, squash, golf, or alpine skiing rotate the upper body under load. Healthy bones tolerate this well, but with low bone density, this combination may overload the vertebrae.
Activities with a high risk of falling also require caution. Horse riding, technical mountain biking, or trampolining are better suited for individuals with stable bones. A fall onto the back or hip can quickly cause serious damage in osteoporosis.
Anyone who enjoys deadlifting should first learn proper technique with a neutral spine and hinge from the hips rather than the back.
Rotational movements under load are another issue. Russian twists with a weight plate or woodchopper cable exercises combine pressure and spinal rotation at the same time, which the spine tolerates poorly in osteoporosis.
What remains is still a wide range of safe activities:
- Swimming
- Walking
- Cycling on an exercise bike
- Rowing on a rowing machine
- Dancing
- Strength training with controlled technique
Preventing Osteoporosis During Menopause
The hormone estrogen protects the bones. As estrogen levels decline during menopause, bone breakdown accelerates significantly. This phase largely determines how stable the skeleton remains later in life.
The importance of this becomes clear in the LIFTMOR study from Australia’s Griffith University. A total of 101 postmenopausal women with low bone density trained heavily twice per week for eight months. The program included squats, deadlifts, and overhead presses performed with high loads and proper technique. The results were significant: bone density in the lumbar spine and femoral neck increased measurably, posture improved, and injury rates did not increase. Heavy strength training can therefore still be highly effective even after bone density has already declined. (3)
