How much weight should you lift for bone health?

Choose a starting load with individual guidance, then use your records to support gradual progress.

Awaiting clinical review — written from published sources and not yet checked by a clinician. Talk to your provider before acting on it.

Key takeaways

  • There is no single weight that suits everyone with osteoporosis.
  • LIFTMOR studied closely supervised heavy lifting; its loading is not a home starting prescription.
  • Record every working set and review increases with attention to technique, symptoms and recovery.

Start with an individual plan

Your starting load depends on your experience, fracture history, symptoms, movement control and available supervision. A clinician experienced in osteoporosis can help choose the exercise and dose. You do not need to prove yourself with a maximum-effort lift to start using this app.

What LIFTMOR actually studied

LIFTMOR compared eight months of twice-weekly, 30-minute supervised high-intensity resistance and impact training with low-intensity home exercise in selected postmenopausal women with low bone mass. Its heavy resistance prescription was five sets of five repetitions above 85% of one-repetition maximum. These are research conditions, not instructions to attempt that load alone.

What an effort rating tells you

Bone Builder asks you to rate effort from 1 to 10, with 10 representing maximum effort. An effort rating is subjective. It does not establish safe technique, tell you your fracture risk or precisely calculate a percentage of your maximum. Record how the set actually felt rather than the effort you hoped to achieve.

How the app suggests an increase

For eligible weighted sessions, the app looks for the full current set target at one consistent load, the top of the repetition range and effort within the target. Conservative progression requires two successful sessions at the same weight. Missing records, mixed working weights or an incomplete recent attempt do not earn an increase. Read How to progress for the workflow.

Suggestions also account for training breaks, difficult sessions and equipment increments. If the next equipment step exceeds the app’s percentage limit, it holds the weight. Your clinician may recommend a different approach; these software rules are not a validated Bone Fit or LIFTMOR protocol.

Keep the research and your plan distinct

Bone Fit is training for professionals who adapt exercise for people with osteoporosis. It is not a single standardized home program. Peak is a 12-week adaptation that differs from LIFTMOR in exercise split, duration and loading templates. Its percentage-based working loads, including the first load, must be selected with direct clinical supervision.

Completing a week does not establish readiness for a heavier load. Repeat, modify or pause your plan with individual guidance when needed. Stop exercise for new pain or warning symptoms and seek appropriate care.

Frequently asked questions

Should I test my one-repetition maximum?

Do not test a maximum on your own to use Bone Builder. A qualified clinician can decide whether any strength testing is appropriate and select a starting load.

Does an increase mean my bone density improved?

No. Exercise records describe performance. Bone density is assessed separately with DXA and interpreted in the context of your clinical care.
