Standing Core Interval Training Workout

Length: 45 sec work / 10 sec rest. video shows how-to and 1 round
Equipment: dumbbells of various weights... or not

I love this workout.  It's dynamic and unique.  I did this a few days ago... 2 rounds was enough for me.  I used one 8-lb dumbbell and a set of 3-lb dumbbells.  I'll be doing this one again, for sure.

Enjoy yourself. Have fun. Keep going. Never give up.
