I think we still owe JoshuaHardcastle an answer I couldn’t address. All I know is that EMS Resistance Strength programs work at the lower level of FT type IIa fibers (50-70 Hz); Maximum Strength EMS programs work between 75 and 100 Hz to activate all fibers at the native frequencies of FT type IIa; and Explosive Strength EMS programs work above 100 Hz (up to 120 Hz), to work all fibers at the native frequencies of FT type IIx. However, I’m not know much about coaching. Charlie and Number Two (and Lyle?), what EMS program would you recommend to complement voluntary training done to promote hypertrophy?
