Hi all! I am new to this site and I specifically signed up for it in order to get some very needed information. I was referred to this site by a friend who told me it was a good place to get some questions answered. I'm 20 years old and I consider myself too small! I'm about 5'4 and my weight in my opinion is below what I would like it to be. I may be thin but I am far from "toned" I have barely any muscle mass and I am pretty inactive. I tend to go through workout phases where I go hard for a month and then give up. My problem is I don't know what ratio of lifting to cardio I should do and I stress about it! I've heard 3 days of lifting to 3 days of cardio and also I've heard five days lifting a different muscle group each day to 3 days of cardio. I want to see results and I am willing to commit the time to good workouts if I have the right plan. I would ideally like to see muscle growth in all parts of my body and to "tone" up if that word can be used. Especially in my legs! I don't want to slim down but I would also like to stay lean and so cardio is a must for me in addition to the benefits for my health. I work out at my school gym during my breaks from classes and because of this the plan of lifting upper and lower body every other day seems to fit my time schedule the best. Any suggestions? Please help! I don't want to stress over working out it's supposed to reduce my stress!
