posting trot

Hey y'all... I'm a slow learner. I've been riding for longer than I'd like to admit, given my progress, but I can't get my body to do what I want it to. So, please.... can someone share a way to help me learn to give leg without squeezing my thighs? Any tricks, ground exercises, or better ways...

Hello everyone! So recently I've had some issues with my posting trot. My trainer says I'm posting too fast and need to slow my posts down, but I can't seem to get them to go much slower. Do you guys have any tips about getting you posts slower? Any advice would be appreciated. Thanks!
