Exercise and bone loading

Bone responds to load.

Walking alone does not give the same signal as resistance or impact training.

Bone is mechanosensitive: it responds to load (strain) rather than “exercise” in general. Walking and steady-state cardio usually create only low-to-moderate strain on most skeletal sites (especially spine and hip), so they tend to maintain or modestly slow loss rather than drive meaningful osteoblast-mediated gains in density.

Core message

Resistance training is central for maintaining or building bone.

Cardio alone is not enough for the same osteoblast signal.

Walking with a weighted vest is not an effective bone-building substitute.

Movement ideas

jumping into a squat (not recommended for bone mets or anyone with flexibility challenges in their ankles/achilles because of increased impact on lower back)
chin-ups
drop landings (heel drops)
squats/squat holds (best for those with bone mets, low back instability, or ankle flexibility challenges, along with using a vibration plate)

Anyone with a history of lower back pain, disc compression, or bone metastases should consult a physician before attempting new movements.

These are high-value bone-loading patterns when done for 15–30 reps, 3–5 times each week.

Short daily jumping intervals or vibration-plate use can also be part of the plan.

One example rhythm is 1 minute on and 1 minute off.

DXA and intervention trials consistently show superior BMD improvements with progressive resistance and impact programs vs walking-only programs.

Important caution for people with bone metastases

Women with active or previous bone metastases should get guidance from a qualified oncology exercise specialist before trying impact or high-load work.

That caution applies even if the movement looks simple in a general-public video.

Practical takeaway

If bone safety is uncertain, get clearance first.

Then build an individual plan around load tolerance, fracture risk, pain, and treatment status.

High-impact exercise is not automatically safe in metastatic bone disease.

Clear the plan with a suitable clinician or oncology exercise specialist first.
