I got two different situations.....my girl is a soph. and she plays softball. She wants to get more toned. I have been told cardio is the key....but, for how long and how many days a week? IS DIET VERY IMPORTANT? and if so what should I do about that. Then, I have two 20 year old girls that are wanting me to train them. They are wanting to get ready for the summer. One could use some tone and one could use some muscle but she wants some abs(as all women do). What do you recommend I do with them? As far as training splits and all. LET ME KNOW
