Kyrpa have done some trials for girth-specific workouts. Including US heat with clamping.
As per now it seems bundled stretches have provided the best results so far.
I have done a couple of weeks trial with US clamping(dual setup with US2000 1MHz)
Aprox 106-107% expansion. But unfortunately the temperature are not consistent above therapeutic levels during the session.
I’m uncertain if there are any trials with 3MHz equipment.
Does your 106% to 107% expansion mean an additional 6-7% over clamping without US heat?
