You're gonna have to take off the training wheels someday.
Step out of your comfort zone. Really, if you're just starting out with weight training, machines are not the way to go. You won't be properly exercising all the ancillary muscles, and you'll develop an imbalance of strength. This can lead to injury later on, when you're actually trying to lift something heavy outside of the gym. Hire a trainer for a couple months, and learn the proper form for various weightlifting exercises. Then ditch the trainer and start doing your own research. You'll be a gym pro, in no time.
