These questions are to any and all.

I have a question regarding the frequency. If you were working at a frequency of 75Hz could you extend the period beyond 10 seconds. Couldn’t you extend the period to around 40-50 seconds? The only reserve I have about this is that it could be hard to maintain a high level of contraction.
Another question, I have been incorporating stim lately and the first few weeks I felt good solid contractions, but the last two sessions it has been more painful and more of a straining sensation at a lower intensity than what I have been doing. Is there a reason for this. I have been doing 10/50 at 100Hz.

Q1: Why would you want to?
Q2: How many weeks has it been?
