A.They say “Two heads are better than one!” With Emsculpt 1 or 2 paddles can “do the trick.” If the abdomen is wide enough to accomodate two paddles without the paddles touching each other then 2 are used. If the abdomen is not wide then one paddle is enough. In both cases the abdominal muscles are stimulated to supra-maximal contractions and the results are equivalently good.Good luck and be well.
