I know people who can grow a lot of muscle doing light weight and also ones who gain it on the low rep schemes. It's highly individual. I typically recommend women to follow ranges 1 and 2. The strength range will increase your bone density helping to prevent osteoporosis and will provide you with strength to make every day tasks easier. Range 2 will add muscle helping to raise your metabolism and burn fat.
Definition is largely a function of bodyfat levels, and bodyfat is largely a function of diet.
The lifting will help, but without a proper nutrition program aimed at fat reduction the definition will be hard to come by. Messages entered in all CAPS will be deleted. Review your message and its format prior to posting. Your ideal rep range changes depending on your training goal. It adds muscle size the best for most people, a moderate amount of strength, and a moderate amount of muscular endurance.
