I've always been leery of weights - it takes me months of very steady progress before I feel at home with them. By comparison: Yoga and Cardio come naturally to me. The only time I did weights seriously (and by that I mean as a supplement to my cardio stuff) was in my twenties.

I also tend to get injured with weights easily with long recovery times. I've also had two minor back surgeries in the last 20 years - disk tucks.

I however, feel that, as I get older, I really need to add weights as I feel my muscle loss is now no laughing matter.

I do hot yoga 4 times a week.

I'm not really interested in bulking up - I just want to loose weight, get in better shape and look and feel better. 

So the question is - Is adding weight training to my yoga routine still a good idea? and if so any important notes that I should know about.
