Struggling with pelvic floor exercises

Does anyone else feel like they are struggling with pelvic floor exercises? I’m 17+5 and still can’t master the long holds!

I did have a giant cyst that weighed my pelvic floor down prior to pregnancy so feel like this definitely isnt going in my favour, but feel like I’m getting frustrated because I’m focusing on the counting and find I’ve relaxed by the end of the 10 seconds 🤦🏼‍♀️

Did anyone find an actual physical kegel helped them? I’m tempted to buy a set to try 🤞🏻
