Hi. I'm not really a member of Ballroom... Just a concerned individual. I used to teach for Arthur Murray's International and know how hard latin motion can be to most of us. About five percent of the population can simply "do it" while the rest of us (I include myself in this) must struggle through mastering the skill. I call it a skill because I have always felt it should be taught separately from the dance (although I use rumba to teach it). It is a skill set all its own. However, I do believe it is a door that must be passed before dance comes to life. Mostly, I suppose, this is just encouragement to not surrender. Remember, slow is better. If you can't do it slowly, you can't do it fast. Start in rumba and master it there first. My good wishes to you.
There are several exercises that can be done at home and can be found on you tube. One is Feet apart . Weight on left leg which is straight. The other pointing to the side with the heel off the floor. Move your weight so that the right foot is flat on the floor. Then and only then send your complete weight over that foot. Just keep repeating from side to side. Now try stepping forward or back with the same kind of action. Its all there if you look for it. That is just one of four examples under Hip Actions.
