The question: “You do a workout that only takes a few minutes? How bad can that be?”
The answer: It can be really bad.
Check the video below for footage of Jason Khalipa’s final rep from the 2010 Crossfit Games first event. Khalipa is a top competitor and won the 2008 CrossFit Games. The barbell is 135 lbs. That’s 90 lbs less than Khalipa’s max. It’s a weight which under normal, non stressed circumstances Khalipa would throw around with ease. At the point the video begins Khalipa is about to complete a workout which was composed of 9 muscle ups then 9 squat snatches, 7 muscle ups then 7 squat snatches, and finally 5 muscle ups and 5 squat snatches. Khalipa has only to lock out the bar overhead one time to complete the workout. He has completed the rest of the workout in a little over three minutes. Video below:
