You should have bought a bench press squat rack combo and then you would have been able to do proper lifting, ie bench, squat, deadlift, rows and military press, the things that shock your body into an anabolic state and make you grow muscle. That aint gonna really be possible on that thing you bought but fvck it -
just go and start lifting mate. Aim for 10 reps on each exercise, and 3 sets of each exercise you do - and the last 3 should be difficult, the 10th almost impossible.
With that machine you can do pec flyes, cable pullups, tricep push downs, preacher curl, leg extensions and maybe a couple other things. Find out what they are and go to work on them.
After 3 months if you are enjoying it and/or want to keep it up, sell the workout system and either join a gym or buy a bench squat rack combo with olympic barbell weights and dumbells. (like I pointed out to you in your other thread)
