Why Weight-Bearing and Impact Exercise Is Essential for Strong, Healthy Bones

The science behind how lifting, loading and jumping protect your bones as we age

Bone health is one of the most critical and overlooked aspects of wellbeing for women.

As oestrogen levels decline, the rate of bone loss accelerates rapidly, increasing the risk of osteopenia, osteoporosis and fractures later in life.

The good news is that exercise has a direct, powerful and scientifically proven effect on bone strength and it is something within everyone’s control.

When programmed correctly, a combination of weight-bearing exercise, strength training and controlled impact work (such as jumping, hopping and skipping) provides the stimulus bones need to remain strong, dense and resilient, particularly at the hips, spine and legs.

Understanding Bone Loss as We Age

Oestrogen plays a foundational role in bone remodelling. It helps regulate the balance between bone breakdown (resorption) and bone formation. As oestrogen declines, bone breakdown accelerates while bone-building cells (osteoblasts) become less active — leading to a net loss of bone density.

Key facts every woman should know

• Women can lose up to 10% of their bone density in the first five years after menopause (UK National Osteoporosis Guideline Group, 2021).

• 1 in 2 women over the age of 50 will experience an osteoporosis-related fracture (Royal Osteoporosis Society, 2020).

• Hip fractures are associated with a 20–24% increase in mortality within 12 months (National Osteoporosis Foundation).

• The Royal Osteoporosis Society recommends regular weight-bearing exercise as a key strategy to slow age- and menopause-related bone loss.

What Is Weight-Bearing Exercise?

Weight-bearing exercise refers to activities where the body works against gravity while the feet remain in contact with the ground. This mechanical loading sends an important signal to the bones to maintain or increase their density.

Examples include:

• walking

• stair climbing

• jogging

• dancing

• squats

• lunges

• step-ups

While walking is beneficial, it is not sufficient on its own to protect bone health as we age. Bones require progressively greater loads to adapt.

Why Strength Training Is Essential

Strength (or resistance) training doesn’t just build muscle — it builds bone.

When muscles contract against resistance, they pull on the bones, creating mechanical tension that stimulates bone formation. This is one of the most effective ways to target bone density at clinically important sites such as the hips and spine.

Effective strength training for bone health means:

✔ 2–4 sessions per week

✔ Moderate to heavy loads

✔ Compound movements (squats, lunges, deadlifts, rows, presses)

✔ 6–12 repetitions with progressive overload

✔ Good technique and structured programming

Light weights and endless repetitions may improve muscular endurance, but they are not enough to stimulate meaningful changes in bone density.

The Power of Impact, Jumping and Plyometrics

Bones respond particularly well to short, sharp forces — which is why impact training becomes important. Impact-based exercises include:

• small hops

• low jumps

• skipping

• box step-offs

• lateral bounds

• low-level plyometrics

Importantly, high impact or high volume is not required. Research shows that even 10–20 controlled landings, performed a few times per week, can provide a meaningful stimulus for bone adaptation when introduced progressively and safely.

Why Variety Matters

Bones adapt to change, not repetition. Performing the same movement patterns over and over leads to diminishing returns.

A well-designed bone-strengthening programme includes variation in:

✔ direction (forward, backward, lateral)

✔ speed

✔ load

✔ type of impact

✔ movement patterns

Strength + load + impact = the strongest stimulus for bone health

Benefits Beyond Bone Health

Weight-bearing and impact training provide benefits that extend far beyond bone density alone. These include:

• increased muscle mass

• improved balance and coordination

• reduced risk of falls

• better joint stability

• improved posture

• greater confidence in movement

• improved metabolic health

• long-term independence and resilience

Women who continue to lift, load and move dynamically as they age are far more likely to maintain physical capability, confidence and quality of life.

Summary

Menopause accelerates bone loss — but the right type of exercise can significantly slow, halt or even partially reverse that decline.

• Walking alone isn’t enough.

• Light weights aren’t enough.

Bones need progressive load, muscular tension and controlled impact to stay strong.

Strength training combined with weight-bearing and impact exercise is one of the most powerful, evidence-based investments a woman can make in her long-term health.

Need help to put this into action?

If you’re unsure how to start strength or impact training safely — or how to adapt your training during menopause — getting the right guidance matters.

I help women (and men!) to build strong, healthy, leaner bodies that support bone health, muscle strength and confidence as they age.
