If you're eating enough (common wisdom says AT LEAST 1,200 calories a day) and you have 10 pounds to lose you might want to consider interval training. Zumba is fun and great for your health but it's not particulary efficient for losing wieght especially if you're already at healthy weight.
You didn't mention what kind of strength training you're doing but if weight loss is your goal and you're doing "traditional" wieght lifting where you do a certain amount of reps per set and then rest between sets that might not be the best way to spend your time either.
If you don't know where to start you might want to check out the high intensity interval training workout resources or sparkpeople www.sparkpeople.com/diet-resources.asp?t=h
or you could just do a search for "interval workouts".
With interval workouts you might find yourself spending less time working out and seeing more results. Definitely a good thing in my book.
