juicing

I am just starting out on juicing and I was wondering what to do I am 24 and I am already in good shape but I dont eat as healthy as I could I dont drink sodas and usually dont eat steak or redmeat, no fast food usually. I just ordered juicing for life. I was just wondering how I should juice and what fruit and juices should I mix or not mix and pretty much will take any imformation any one would like to give me. Thanks and God bless John 3:16
