Yep. 80% improve. Might not cure. But will improve, and with that, comes better sexual function - so, stuff the trampoline, use that as a motivator. If you're going to do it, you may as well make ti worth your while...
Brief summary:
clench for 10 secs. You should feel a "drop" when you let go. No drop, you've lost the contraction. You need to be able to clench for 10 secs to stop yourself from pissing your pants when you struggle to unlock your front door.
10 quick flicks. So, clench, clench, clench, x10. That stops you from pissing yourself when you sneeze/laugh/cough
3 floors - imagine you've got a wee lift in your speshul place. Don't think about why that might be too much, just imagine the elevator taking tiny wee people to your first floor (I know, it raises more questions than I'm comfortable with), second floor, third. Then, back down - that's the tricky bit. That stops you from pissing yourself when walking downhill in high heels.
Doing those three exercises three times a day, every day, for the rest of your life, will improve the problems you have, prevent further problems and make shagging worth your trouble.
Mind, that's for simple stress incontinence. If you have degree of prolapse, or bladder frequency, or urgency then it's a bit more complicated and you can't be guaranteed 80% improvement within a month of clenching. Will still help, but best see your GP.
