Behind the Alter-G Treadmill

When deflated the Alter-G anti-gravity treadmill looks like any normal treadmill you'd see at your local gym--wrapped in a hefty bag.

Once the machine is turned on the user looks like they're standing up through the sunroof of a car.

The Alter-G treadmill creates a seal around the user's waist and then inflates to create a pressurized environment that can take away up to 80% of the users body weight, lessening the pounding to the joints.

"Essentially you become like a cork in a champagne bottle and you can modify just exactly how much pressure is in there," said Chip Schaeffer, the Lakers Director of Athletic Performance/Player Development.

"It's a great rehab tool as well as a conditioning tool. If a guy comes off a couple games in a row and wants to blow his lungs out a little bit, but doesn't want to take the full breadth of his body weight and exhaust himself he can get in there for 15-20 minutes and not fatigue his legs too much."

Andrew Bynum and Chris Mihm have been the main beneficiaries of the new treadmill as they recover from knee and ankle injuries respectively.

After a lengthy recover from multiple ankle surgeries Mihm has a great appreciation for the new piece of equipment.

"This is pretty amazing. It doesn't restrict your movement at all and it allows me to really get some training without all the pounding on my ankle right away."
