I mostly have a limited set of free weights containing two dumbbells and a barbell. This is what I have solely used to build my physique. My set up has worked really well. Saying that, I am considering shelling out for one of those home-multi gyms. My wife reckons she will exercise more if we get one and I always like going heavy on the machines with there being much less chance of injury. I would not give up the free weights though. Anyway, what are some brands I should look at? Some I have looked at so far are pathetic with regards to the weight stacks. We would need something with a fairly substantial weight stack. Any opinions would be welcomed. Thanks!
