Hi there.
This topic came up recently. You may find this thread helpful.
@ Reducing muscle on your lats and traps. You mentioned training or strength, and that you enjoy the compound lifts. DLs really activate those muscles for me, as do training the OLY lifts. It’s fun to train them, but for female aesthetic goals there may be trade offs. DLs and OLY lifts really activate/ hypertrophy traps in me.
@ Diet. If you are already at 18% BF, then backing off of lifting while eating at a mild deficit will help you loose some of your muscle mass.
