There can be a variety of reasons for soreness...
I know that until I worked on my imbalances with a trainer, I was sore more often than not. In fact I was constantly complaining about DOMS.
But I also felt that as an older woman (over 50), that if I didn't use it, I would lose it--so I've persisted.
How do you set up your "program" of what you lift, what areas you target, how much weight, etc.?? Form is REALLY important. You don't have to lift quickly (say, to get it done). Slower is better. How many sets? reps?
Keep working at it and don't give up! It IS worth it!
