Are there any good fitness brands having sales right now?
i am not sure about  it  
I'm hoping to improve my home gym and looking for a treadmill
that is a great idea i think  
It's no fun to run outside when its raining or freezing. I have used a rowing machine, but a treadmill would be helpful too. Is there other cardio I can do indoors?
that is a great idea think so .
I also need to find some weights. I hear elastic bands are good for training too, but weights seem more fun. Is there any evidence one is better than the other?
is it helpful for bodybuilding ?
Thats a good question. I wonder if weights are better for body building and bands are better for lean muscle. Do you know if there is any info on that?
no i have little idea about it.
If i turn my garage into a gym, should I use just 1 wall or turn the whole space into a gym?
