If you are a beginner, it is best to have a personal trainer to guide you, after a few months you will have learned to use equipment correctly and you may consider to continue training on your own or with a partner.
If you can not afford a coach then you have a little more difficult but not impossible, just that you learn on your own to do the exercises and structured routines. You can start with weight training for beginners and then move to others.
Do not get obsessed with one part of your body, includes exercises for abs, arms, back, chest and legs. The muscular development is integral to achieve symmetry. Strive a little more in those places where you see fewer results.
Before going to split routines is recommended to start working with weights exercising all muscle groups for 3 sessions for several weeks to reach a minimum of conditions.
