In honor of Mark Twight (the inventor of the 300) and the two guys that posted their "300" workout on YouTube that inspired me to start using it in my own fitness regimen; I proudly present my own humble effort.
I hope they like it. :)
EDIT: Very nearly equaled my best ever with a time of 24:50 as of 1-26-08!!! That magic 20 minute mark is going to be hell to beat though...Oh, yeah, and just to add something else - I am 38 years old and doing this workout. :)
