This is another one of the workouts i have been doing lately. It's pretty killer on the abs. Just once doing it and i was feeling the burn for days. This is definitely going to be on the top of my list as a workout to do to get beach ready. This workout doesn't include a lot of cardio so i suggest doing in along with some added cardio of your choice, i do it with aerobic step or Just Dance 3, and the whole workout can take me around 45-60 minutes or if i only do the Abs & Arms, 20 minutes. Youtube any moves you don't know and give it a try!
