I am brand new to lifting and really would like to build some muscle. However, I don't really have anyone that I can go work out with. Since I don't have anyone to spot me, I feel like if I am going to be lifting heavy weights that that would be dangerous. However, the gym I go to does have some nautilus machines. Since those don't require a spotter, I was wondering if those work as well as free weights?
I have never seen a serious lifter using the machines before but I can't tell if that is because they don't work, or because of some macho thing that compels people to use free weights instead. I am still in the process of finding a good routine but the ones I have been finding talk about free weights and I just didn't know if that would be safe for me as a beginner without a spotter.
