So this past weekend I had the opportunity to checkout the Jump-off Workout with Celebrity Fitness Trainer Mark Jenkins. He has trained celebrities like Mary J Blige, Brandy, D'Angelo, and others. A friend of my invited to me this class at Soma Body Fit in D.C. His 70 minute class the "Jump-off" is so Intense! If you are in the D.C. area I strongly recommend you check him out. He does classes a Soma Body Fit and private classes at the Mandarin Oriental.
Here is a description of the class:
