Hello all

I'm starting over again with basically everything. I did the whole gym membership thing about three years ago for about three months. I really liked using all the weight machines. I just got a gym membership again (about two weeks now) and I've been using the machines after 10-30 minutes of cardio. But I really don't know much about the machines and I feel like I should have a routine instead of machine hopping. Any helpful tips?
