Do you ever get hyper after working out? boy do i ever (ask matthew) i constantly have about 20 thousand times more energy after i work out...not completely after it usually hits me in the afternoon and boy do i have bundles of energy built up. i seriously go crazy matthew just laughs at me as i talk about the most random things with little to no breaths in between...im sure its truly amusing to most people but i ask important questions that rarely get answers causing me to get emotional (ok it could be the fact i don't stop for him to answer but we'll pretend that i do). sooooo if you feel like you have no energy seriously do some insanity----you'll be bouncing off the walls once you finally are able to do the work out with out DYING!!!!! but really its a fantastic workout!
