Wear a thick pad in your underwear if you leak during some of those exercises. I know I did. I think it was particularly bad when doing an exercise that required me to stand up and sit down while doing a kagel. This happens even after fully emptying your bladder, Urine builds up in the bladder much quicker than one would expect.

If you totally empty your bladder when doing them then maybe you need an artificial sphincter. There is a condom like aid you could get that empties like a catheter, don’t know the name, Someone in this form mentioned it so hopefully they will help.
