Guardian Sensor Taping

Hello! I just got the guardian sensor with my medtronic 670G and I am loving it! However, I was wondering if anyone has any advice as far as taping goes? I have had it a few months, and I work out (and sweat) pretty aggressively. I find that it falls off around 4 of the 7 days its supposed to last. Have you found good tape or methods? I tried simpatch but that didnt work at all.

Thanks!

Edit: The sport is karate, if that helps.
