Yeah, I’ve gotten a cramp in my PC muscle before (Or BC, still not able to differentiate the two in terms of feeling).
Really painful.
If you’re starting out, something along the lines of 3 sets of 20 should be a good starting point, this will seem like nothing to seasoned ‘kegelers’ who are probably ‘kegelling’ while reading this. Lol.
But, gradually increase the amount of reps and sets as the weeks go by and you’ll notice the difference in no time..
Best thing about them is that they can be done anywhere, without people really noticing you’re doing them. So the amount you will eventually be able to do per day could be colossal.
Depending on your current strength I’d say take a day and do as many as you can until you feel fatigued, then, gauge how many you can do realistically per day from that.
