Pilates is wonderful. I personally love Pilates.
But Pilates alone does not provide the same progressive bone-loading stimulus that heavy resistance training can.
You can add springs. You can make the movements harder. You can twist, balance and challenge your core. Those things have value.
But they are not the same as progressively loading a squat, deadlift, press, pull or carry with substantial external resistance.
Bones adapt to load.
Bone is constantly remodeling. Osteoclasts resorb old bone, while osteoblasts form new bone. Mechanical loading is one of the signals that influences this process — and as we get older, providing enough stimulus becomes increasingly important.
This isn’t just theory.
In the LIFTMOR randomized controlled trial, postmenopausal women with low bone mass performed supervised high-intensity resistance and impact training for 8 months.
The result?
Lumbar spine BMD increased by 2.9% in the training group, while the control group declined by 1.2%.
Research specifically examining Pilates in postmenopausal women has not shown comparable improvements in bone mineral density at the lumbar spine, total hip or femoral neck.
That doesn’t make Pilates bad.
It means Pilates and strength training have different jobs.
Keep Pilates for the things it does beautifully.
But if protecting muscle and bone after 40 is the goal:
KEEP PILATES. ADD STRENGTH.
