Jump Training for Women: The Bone Density Protocol for Perimenopause and Your 40s

By the APEX PWR Team | Tigard, Oregon | Published May 13, 2026

If you're a woman in your late 30s or 40s, the most overlooked piece of your training is also the most evidence-backed for protecting your bones over the next 40 years: brief, intentional, well-programmed jump training.

Most women in this demographic are doing yoga, pilates, walking, maybe some lifting. All of it has value. None of it produces the ground reaction forces that bone responds to. Jump training does — and the research is striking: as little as 10 jumps a day, twice a day, twice a week, produces measurable improvements in hip bone density in premenopausal women (Tucker et al., 2015).

This isn't a CrossFit workout. It isn't plyo intervals until you're gassed. It's a small, specific stimulus delivered at the right intensity and the right frequency.

Key Takeaways: The 5-Second Version

Jump training is the single most studied bone-building stimulus for women in their 30s, 40s, and 50s.
The dose is tiny. As few as 10 to 20 jumps, twice daily, twice weekly, produces measurable bone density gains in the hip.
Perimenopause accelerates bone loss. Women lose 3 to 5 percent per year in the first 5 to 7 years postmenopause. Starting jump training before that decline begins is the highest leverage move.
Jumping is not just for athletes. It's for any woman who wants to walk into her 70s with strong hips and a body that does what she wants.
APEX programs jump training into every strength workout — scaled to the individual, integrated with lifting, dosed conservatively.

Why Jump Training, Specifically

Bone responds to mechanical strain — specifically, high-magnitude, high-rate strain at sites that experience clinically meaningful fracture risk: the hip and the spine.

Walking

~1.0–1.3× body weight ground reaction force. Good for cardiovascular health. Not enough for bone.

Running

~2.5–2.8× body weight. Better. Still below the osteogenic threshold at the hip.

Jumping

3–6× body weight at the hip. This is the threshold range bone cells actually respond to.

The Tucker 2015 study at BYU put premenopausal women through a year of jumping (10 to 20 jumps, twice a day) and measured significant improvement in hip BMD compared to controls. The women jumped onto a hard floor in athletic shoes. That was the entire intervention.

Two earlier studies (Bassey 1998, Clissold 2020) reached similar conclusions: brief, frequent jump exposure produces site-specific bone gains in premenopausal women that walking, cycling, and even resistance training alone don't replicate.

The Perimenopause Window: Why Now Matters Most

Estrogen plays a protective role in bone density. As estrogen levels drop during perimenopause and into postmenopause, bone loss accelerates dramatically.

Stage	Annual Bone Loss
Ages 35 to perimenopause	~0.5–1%
Perimenopause onset	Loss begins to accelerate
First 5–7 years postmenopause	3–5% (sometimes higher)
After year 7 postmenopause	Returns to ~0.5–1%

A woman who enters perimenopause with high bone mass takes the same percentage hit, but starts from a much higher floor. A woman who enters with already-low bone mass can land in osteopenia or osteoporosis within a decade.

Jump training before menopause raises the floor you start from. Jump training during and after menopause slows the rate of decline. Both windows matter.

The Protocol That Actually Works

Based on Tucker 2015 and replications, here is the minimum effective dose:

The dose

10 to 20 jumps per session
2 sessions per day (separated by at least 8 hours)
4 to 7 days per week
30 second to 1 minute rest between jumps

The technique

Jump straight up as high as possible
Land softly through your full foot, then heel
Bend knees on landing to absorb impact
Athletic shoes on a hard surface (wood, concrete with thin mat, or rubber gym floor)

The progression

Weeks 1–2

5 jumps twice daily, 3 days per week. Teaching the body how to land.

Weeks 3–4

10 jumps twice daily, 4 days per week. Building the habit and loading the hip.

Weeks 5+

20 jumps twice daily, 4 to 7 days per week. Full protocol. Total daily time: about 60 seconds.

60 seconds a day. The smallest, highest-yield intervention in the bone density literature.

Why This Looks Different at APEX

We don't program "just jumps" as a standalone protocol. At APEX, jump training is woven into the strength workouts we already do — three times a week, alongside lifting — for three reasons:

Compliance is higher when it's part of the workout, not a homework assignment.
Strength training amplifies the bone response. Heavy resistance loading plus impact loading produces greater bone adaptations than either alone.
Programming allows us to scale. A woman recovering from knee surgery doesn't do the same jumps as a former athlete. Both can build bone.

The progression from a 35-year-old new lifter to a 50-year-old experienced athlete looks completely different. The dose principle is the same. The exercise selection is not.

Who Should Be Jumping

Almost every woman 30 to 60 without a contraindication.

Good Candidates

Women in their 30s or 40s building a bone foundation
Perimenopausal women protecting against accelerated loss
Postmenopausal women with osteopenia (supervised programming)
Women with a family history of osteoporosis
Women who have never done structured impact training

Requires Supervised Programming

Women with diagnosed osteoporosis
Women recovering from recent surgery or injury
Women with diagnosed pelvic floor dysfunction
Women with current stress fracture or unhealed bone injury

If you're in any of the supervised categories, work with a coach. The right modifications make jumping safe and beneficial. Going it alone is what gets people hurt.

The Pelvic Floor Concern (and the Real Story)

A common reason women avoid jumping is pelvic floor concerns: leakage during jumps, prolapse fears, postpartum hesitation.

The right answer isn't to avoid jumping. The right answer is to address the pelvic floor issue and progress jumping appropriately. Pelvic floor PT plus graduated impact loading is the gold standard. Jumping with a strong pelvic floor protects bone. Avoiding jumping because of a weak pelvic floor leaves you with low bone density and a weak pelvic floor.

If this is you, work with a pelvic floor physical therapist on the pelvic floor side and a coach on the impact loading side. The two run in parallel.

Nutrition: The Other Half of the Equation

You can't build bone without raw materials. The three that matter most:

Protein

0.7–1.0g

Per pound of bodyweight per day. Bone matrix is roughly half collagen protein.

Calcium

1,000–1,200mg

Per day. 1,000mg under age 50, 1,200mg after. Food first — dairy, leafy greens, fish with bones.

Vitamin D

30–50 ng/mL

Target blood level. Test it, don't guess. Supplement as needed.

Our Thorne dispensary gives APEX clients lifetime 25 percent off pharmaceutical-grade calcium, vitamin D, and protein options. For the full nutrition framework that supports bone health, Jennie Carolan MS, our staff nutritionist, builds the nutritional side alongside the training side.

Build Bone. Protect the Decades Ahead.

Start with a DEXA baseline to see where you stand, then build the training plan around the data.

Frequently Asked Questions

Will jumping hurt my joints?

Done with proper progression and technique, no. Bone, cartilage, tendon, and ligament all adapt to impact loading when the dose is appropriate. The risk is in doing too much too soon, or doing it with poor mechanics. Programmed correctly, jump training reduces long-term joint pain by maintaining the muscle and bone that support the joint.

I have osteopenia already. Should I still jump?

Likely yes, but under supervision. The LIFTMOR protocol included impact training in postmenopausal women with osteopenia and osteoporosis and was both effective and safe in that population. The key is appropriate exercise selection and progression by someone who knows what they're doing.

How long until I see changes on a DEXA scan?

6 to 12 months at minimum. Bone remodeling is slow. Plan for a baseline scan, then a follow-up at 12 to 18 months. Don't get scans too close together. The signal is in the long arc.

Can I just do this at home?

For the basic protocol (10 to 20 vertical jumps, twice daily), yes. For anything more nuanced — an injury, osteoporosis, pelvic floor issues, or integrating jumps with strength training — work with a coach.

What if I haven't jumped in 20 years?

Start with 5 jumps once a day for a week. Build to twice daily. Build to 10 reps. The first month is teaching your body how to land. The bone changes come later, when consistency is locked in.

I'm postmenopausal. Is it too late?

No. The LIFTMOR studies were in postmenopausal women with osteopenia and osteoporosis, and both showed improvement. The longer you've been postmenopausal, the more important supervised programming becomes — but it's never too late to slow the decline.
