Use whatever equipment you have, but I personally love free weights.

So I shouldn't get it if I want to add muscles?

Not saying that. Depending on your level on fitness, it can add some.

Any type of equipment will work for a certain amount of time. If you were to get a bowflex use it for 1-2 months, then switch to free weights. This way your body is always thrown off and doesn't adapt to certain movements, weights, range of motions, etc. Your body will always be off balance so to speak.

As long as you are taking in to account your nutrition, recuperation, and supplementation you will grow. This is what is more important IMO:

1 Diet- Important as this really makes or breaks your progress
2 Training- This is the stimuli for you body to make changes
3 Recuperation- Without this your muscles won't grow and you'll become overtrained. So get your required sleep and rest!
4. Supplements- This is your Creatine, NO2, AAS, anything in that realm.

Having these things working together will have an overall positive synergistic effect on your body. And this includes whether you use bow-flex, free weights, Total gym, etc.

Thanks for all the help from everyone. I think I'm going to be getting the bowflex. Two I mainly interested in are the Bowflex Sport Home Gym and theBowflex Motivator 2 Home Gym

Is it worth getting the one for $800 or would the one for $600 get me the same results?

keep in mind your going to need help putting it together it looks pretty simple on tv but theres lot of parts to it

I didn't really see any difference in them. :confused:

I see one difference in them, $200.00 :)

the more expensive one offers 10 more exercises and i think thats just about it
