My old acting teacher told us about it like 2 years ago. I tried it and fell off the wagon as life got busier.
I really, really want to find a treadmill. I can't/won't run outside (I can run for much longer on a treadmill. I have no idea why), but I think if I had a treadmill to run on I'd commit to it a lot better. they're just sooo freakin expensive.
