LeBron James Trains on Anti-Gravity Treadmill

Just a few days ago we saw Kobe Bryant training on an anti-gravity treadmill.

Naturally, LeBron James couldn't be one-upped.

While Kobe is rehabbing a torn Achilles, LeBron's reasons aren't so clear.

Perhaps it is intended to speed up the training process. Regardless, the (presumed) oxygen mask is a pretty cool add-on.
