Work out routines

:drinker: Just looking too get healthy. I am wondering about work out routines at the gym. I go to planet fitness and do 15 min on the tred or elliptical then ab room and or the 30 min work out then the bike to end I set the machines for 50 to 30 lbs. this is for now I plan on stepping it up as I go. Should I do some thing else? Oh and I try to do 20 to15 reps at each machine.
