Osteoporosis and Osteopenia: What They Are, Why They Matter, and How Movement Can Protect Your Bones

As we age, our bones change. It’s a natural part of life: bone is living tissue that constantly breaks down and rebuilds. Before about age 30–35, bone formation outpaces bone loss — so our skeletal system gets stronger. But after that peak, bone density begins to decline slowly, and the rate of loss accelerates with age, particularly in women around menopause. If this loss becomes significant enough, it can lead to osteopenia or osteoporosis, conditions that weaken bones and increase the risk of painful and life-altering fractures.

Understanding the Basics: Osteopenia vs Osteoporosis

Both osteopenia and osteoporosis are diagnosed via a bone mineral density (BMD) test, usually using a DEXA scan. The results are expressed as T-scores, which indicate how your bone density compares with that of a healthy young adult:

Normal bone density: T-score above –1.0
Osteopenia: T-score between –1.0 and –2.5 — meaning bone density is lower than normal, but not low enough to be classified as osteoporosis
Osteoporosis: T-score of –2.5 or below — representing significantly reduced bone mass and a substantially higher fracture risk.

In simple terms, osteopenia is a warning sign — it means “your bone density is lower than ideal and you’re at increased risk,” but it doesn’t automatically mean you’ll get broken bones. Osteoporosis, on the other hand, is a bone-weakening disease where the structure of bone is compromised enough that even what feels like a minor bump or fall can lead to a fracture.

Why This Matters: The Scale of the Problem

Osteoporosis is one of the most common chronic conditions affecting older adults. In the United Kingdom:

An estimated 3.5 million people are living with osteoporosis.
Half of women over age 50 will suffer a fracture due to osteoporosis in their lifetime.
Around 20% of men over 50 will also break a bone because of the condition.
There are more than 500,000 fragility fractures every year in the UK — that’s one every minute.

Fractures of the hip, spine, wrist, and shoulder are common and can significantly impact quality of life — often leading to pain, loss of independence, and increased mortality, especially after hip fractures.

How Bone Responds to Exercise: The Science Behind Movement

Bone isn’t static — it responds to the mechanical loads placed upon it. When bone is loaded (pushed, pulled, compressed), specialised cells called osteoblasts are stimulated to create new bone tissue. Activities that provide impact loading — especially those that generate force through the skeleton — appear to be particularly effective in this process.

Historically, many conservation-level exercise recommendations for bone focused on walking or low-impact activities. However, while walking is excellent for cardiovascular health and general mobility, its impact loading is often too low to stimulate significant increases in bone density.

The type of exercise that really seems to get bone responding? High-impact, brief, or unusual loads — and resistance training. Jumping, stomping, hopping, and weighted activities create a mechanical stimulus that’s far more potent for bone growth than slow, low-impact movement alone.

Key Research: Jumping and Bone Density

One of the most talked-about research studies on jumping and bone health involved 60 premenopausal women who were randomly assigned to two different jumping protocols or a control group. Participants performed either 10 or 20 maximal vertical jumps, twice daily, with rest between each jump — over a period of 16 weeks.

The results were compelling: women in the jump groups experienced significant increases in hip BMD compared to the control group, demonstrating that even a small number of high-impact jumps, performed consistently, can improve bone density.

Meta-analyses of several jumping studies also support the idea that consistent impact exercise significantly increases bone density at the hip and femoral neck — key sites of osteoporotic fractures — especially in women.

A broader randomized trial in women with osteopenia further reinforces this, showing that home-based jumping programs had modest benefits in slowing hip bone loss compared with usual care.

Exercise Matters: Bones, Strength, and Fall Prevention

Beyond bone density alone, exercise delivers multiple protective benefits:

Muscle strength increases: Strong muscles support joints, improve posture, and help absorb forces during movement.
Balance improves: Better balance reduces the risk of falls — one of the biggest causes of fracture among older adults.
Functional capacity increases: Stiffer, stronger muscles and bones help you stay active and confident in daily life.
Exercise may slow or even reverse bone loss: Resistance and impact training have shown positive effects in many populations, including postmenopausal women.

Notably, resistance training — such as weights or bodyweight strength exercises — often ranks highly in research for improving both bone density and functional strength.

Exercise Ideas You Can Use

If you’re a Pilates or yoga teacher, coach, or movement enthusiast incorporating bone-building work, a thoughtful progression is essential. Start with safe foundations that build strength and prepare the body for impact:

Beginner / Foundation Level

Heel Raises: Great for strengthening calves and loading the lower leg and ankle.
Stomping: Purposeful ground contact helps introduce impact in a controlled way.
Power-Up Push-Ups: Upper-body strength work that supports overall skeletal loading.

Progressions Toward Impact

Light Jumping: Begin with low vertical jumps (think “small hops”), focusing on soft, controlled landings.
Very Light Jogging / Spot Jog on the Spot: Introduce gentle impact with a focus on knee alignment and stable hips.

Intermediate / Dynamic Work

Once foundational strength and confidence are established:

Skaters: Lateral movements that load the hips and improve balance.
Spotty Dogs (Alternating Opposite Arm/Leg Raise): Encourages core stability and integration.
Progressive Plyometrics: Direct jumps with soft landings, increasing height or repetitions slowly over weeks.

Practical Tips for Safe Progression

Warm up thoroughly: Activate muscles and joints before impact work.
Start low and slow: Even small jumps can stimulate bone if done consistently.
Focus on landing mechanics: Land softly with bent knees and hips to protect joints.
Rest matters: Bone responds best when loading is interspersed with rest.
Consult first: Those with established osteoporosis or fractures should seek medical or physiotherapy advice before high-impact exercise.

Closing Thoughts: Move Strong for Life

Understanding and addressing bone health isn’t about adding fear or doom — it’s about empowering movement and confidence. Whether your goal is to prevent the progression of osteopenia, support strong bone maintenance, or simply feel stronger and fitter as you age, thoughtful movement has a profound role to play. Combining impact loading, strength training, balance work, and consistency is your best strategy for bone health that supports both performance and long-term wellbeing.

With small, manageable steps — like adding a few purposeful hops into a Pilates or yoga session — you can help build resilience into the skeleton and enrich your clients’ lives from the inside out.
