Try using the weight machines in the gym , start out lifting about 5-10 pounds (not too heavy I would say 20 max) , three times a week do three reps of 15 for each exercise. If that's too tough lift less weight!! Increace your weight every few weeks, you should see a difference in about 30days. This will help you tone, without bulking up!!! I work out at 24hour fitness, and the trainers are good about answering questions. I paid for three personal training sessions and it was money well spent, you tell them your goals and they will tell you the best way to acheive them. I hope this helps
