No this is not the maasai jump. It is a simple 3-4 times a week (with rest days in between) practice/drill. Go to a track or a space of around 70 meters. Sprint as FAST AS YOU POSSIBLY CAN through 70 meters and then walk back each sprint. Do 5 sets of these (5 sprints and then walk back after each one). Apparently (as long as your growth plates are not closed) this will increase your hgh production levels by 700 percent.
