The protocol uses impact as a mechanical input to bone remodeling. Bones continually break down and rebuild through osteoclast and osteoblast activity, and Wright explains that biomechanical signaling is a major prompt for rebuilding. Twenty multidirectional jumps a day convert landing forces into biochemical signals that tell osteoblasts stronger bone is needed. The jumps may be split into two sets of ten, replaced by ten minutes of jump training three times weekly, or made more playful through hopscotch and lateral patterns. Because softer surfaces reduce impact, a rebounder is not equivalent to a firm landing for this goal. Beginners should scale from heel rises and a controlled thud or a low step rather than jumping aggressively after years without impact.
Origin
Wright grounds the protocol in studies of jumping sports and daily jumping, noting that gymnasts show strong bones and that 20 jumps can provide a bone-building stimulus.
Core principles
- 01Bone remodels in response to mechanical signals.
- 02Impact gives osteoblasts a reason to build stronger bone.
- 03Bone-building impact is different from low-impact cardiovascular work.
- 04Beginners can scale the landing before increasing intensity.
How to run it
- 1
Assess impact readiness
Consider whether you have jumped recently and whether your ankles, knees, hips, and balance tolerate landing. Start with a regression when impact is unfamiliar.
Pro tip Use heel rises followed by a controlled thud as an entry point.
Watch out Pain or instability warrants professional assessment rather than forced progression.
- 2
Choose the dose
Complete 20 jumps in a day, either together or as two sets of ten. An alternative supported in the discussion is ten minutes of jump training three times per week.
Pro tip Attach the jumps to an existing daily cue.
- 3
Create useful impact
Land firmly rather than trying to make every landing silent. The impact is the signal the protocol is designed to create.
Pro tip Progress from the floor to a low step only when the current level feels controlled.
Watch out Do not confuse greater impact with reckless height.
- 4
Move in multiple directions
Mix vertical, side-to-side, and patterned jumps. Multidirectional loading varies the signal rather than repeating only one line of movement.
Pro tip Use hopscotch or a jump rope to make the habit less monotonous.
In the wild
A previously sedentary adult begins with heel rises and controlled thuds. After building tolerance, they complete two sets of ten small multidirectional jumps on a firm floor, eventually adding low step-offs while keeping every landing controlled.
→ The person builds a consistent impact habit without beginning at an unnecessarily aggressive level.
Common mistakes
Choosing only soft rebound
A trampoline reduces the impact that provides the intended bone-building signal.
Starting too aggressively
People who have not jumped for years should scale the movement instead of immediately using hard surfaces or high steps.
Is it for you?
Best for
Adults who need a scalable bone-loading habit and can safely tolerate impact.
Not ideal for
People with acute pain, unstable joints, fracture risk, or medical restrictions on jumping without professional guidance.
