LeBron James's Insane Conditioning Drill

Watch LeBron James show off his tremendous athleticism and endurance in this video, taken during a morning training session.

We all know LeBron James is a freak of nature. The 6-foot-8, 250-pounder can run like a gazelle, and his body fat percentage was probably somewhere in the negatives; yet James decided to cut weight during this off-season just to challenge himself and see if he could do it. In the least surprising news of the year, he could.

So how does James keep himself in such incredible shape? While many of his workouts are private, on the morning after the release of his latest shoe, the Nike LeBron XII, at Nike's headquarters in Portland, Oregon, James was up early for a training session, and so were we.

In the conditioning drill you see above, with the help of his agent Rich Paul and former teammate Damon Jones, James receives an outlet pass and sprints to half court from the baseline. He catches the ball in mid-air, runs to the hoop and dunks the ball. He then immediately repeats the drill. The above clip is only about 20 seconds long. But James ran the drill non-stop for about 2 to 3 minutes, collapsing on the baseline when he finished. If you're wondering how James seemingly gets stronger as the game goes on, this drill may be the catalyst.
