So you can leverage this by doing explosive bunny hops on a hard surface to micro fracture you shins
Do it before you go to bed for like 5-10 min and hang your legs of the edge of something when you’re done for like 30 min then gtb this will cause gravity to pull on your shins while the micro fractures do base repairs. There’s a couple videos of guys who grew 3-6 inches after age 18
Also intermittent fasting will do this too by spiking your (HGH human growth hormone) just not to the same extreme
