Good one, Kettlebell/Dumbell swings can you started in the movement with good form.
Also Rack Pulls will help in the meantime.
Sumo Deadlifts are also good, but they also require flexibility in you hips. Still, try them out.
All this along with stretching, overtime, will give you the needed flexibility.
A good idea (if u can afford it) would be to see an ART clinic. Go here to find one near u
Good luck and don't give.
Oh and BTW, EXPECT to be made fun off when u mention wanting a "Brat Pitt Body".
