New Workout

Today in the weight room I wanted to to a core workout with Kris because it's better I feel to workout with friends and because core strength is always good to have.  Here is the video that me and Kris followed during our workout.

The workout was really tough.  It seems simple but when you are doin non stop core excersises,  you can feel the burn within the first minute.  Based on me and Kris' 2 rounds of 20 and 2 rounds of 10,  I would say it's almost impossible to do in 6 minutes.  It took me 7:15 and Kris 8 minutes to finish and the last 2 rounds were cut in half.  It probably would take close to 10 minutes to do the whole thing even if you had a really strong  core.
