welcome bro , good question , ill try and answer best i can
Many times beginning bodybuilders make the mistake of using the routines of professional bodybuilders featured on magazines, when instead they should be using a routine that is geared towards their level. A good beginning routine that uses minimum equipment (namely a pair of dumbbells and a bench) is the following:
3 Days A Week Full Body Routine:
(Perform on 3 non-consecutive days such as Mon/Wed/Fri)
75 Degree Incline DB Bench Press
DB Bench Press
One Arm Rows
DB Pullovers
Bent Over Lateral Raises
DB Upright Rows
Dumbbell Curls
Overhead Triceps Extensions
Leg Extensions
DB Squats
DB Lunges (Press with heels)
Lying Leg Curls
Calf Raises
NOTE: DB = Dumbbell
How to Progress:
Perform 2 sets of each exercise for 10-12 reps and rest 1 minute in between sets. Move up to 3 sets after 4 weeks. At 2 sets per exercise the routine lasts 45 minutes if you rest 1 minute in between sets. At 3 sets it lasts 60 minutes. Do cardio on the days off (20-30 minutes) and also do abs (4 sets of Leg Raises and swiss ball crunches for 15-40 reps).
Remember to warm up before you start (maybe by training abs) and to also stretch before and after training !
Full body workouts will help ease you into body building , when you find you hit a platau you can switch it up in body part split routines but more on that at another time
