Great to see you are wanting to work on your fitness and strength a litle. It cn really help on and off the course.
A couple of exercises wont totally work for you, a complete program will always yield the best results. But if you are new to working out, I always recommend getting a full personal assessment and perhaps a couple of basic personal sessions to teach you some basic moves and form so at least then you can have a good foundation to develop from.
Good look, and the flexibility will indeed come once you start moving with weights, but dont force it by any means.
www.athleticgolftraining.com although geared toward younger golfers does provide lots of general health and fitness tips for golfers. Plenty of youtube videos and even recommended programs that you can try.
