I agree that it's all about the cardio. It's really the most important step in any attempt at feminizing. I have spent the last year feminizing my body and the results from all the running show quickly. Every day it has to be done. If you get it in every day you can afford some lapses in bad eating habits.
I don't go overboard on the weights. Two workouts a week. Chest day is pullovers & pullovers... with some light bench presses.
The second day is legs. Only doing extensions and leg curls. The running will take care of your legs and slim down the manly quads.
I never target workout abs, obliques, deltoids, shoulders, arms, or back. They'll get lean enough if you take care of the cardio.
And eating fruit has to become your new hobby.
