Bynum's Anti-Gravity Treadmill

(Note: Not Andrew Bynum)

Here's a picture of the new anti-gravity treadmill that Andrew Bynum has been running on recently. This dealy is called the G-Trainer and is made by a company called Alter-G. I actually can't say for sure if this is the exact same machine that Bynum is using - you know everyone is making an anti-gravity treadmill nowadays - but I am pretty sure based on the fact that google couldn't find any others. Here are some tidbits from the Alter-G website:

The G-Trainer overcomes limitations such as water resistance and cumbersome harnesses associated with conventional unweighting systems allowing for a natural gait pattern.

Alter-G's technology was originally developed at NASA as part of an effort to help astronauts maintain fitness during prolonged space flight. Alter-G combined this technology with an advanced pressure regulation system and a treadmill to produce the first anti-gravity treadmill. The physical lifting force generated by the G-Trainer comes from a difference in air pressure around the individual's body.

Sounds pretty cool, I guess. I also heard that it roughly costs $75,000. But I was thinking, it was probably more than that because they probably had to make a customized air bag because if you replace the dude in the picture with Andrew Bynum, the top of the bag is probably mid-thigh.
