Hello everyon. I have a few questions if anyone is willing to help me out. I am going to start P90X soon but before I do I need to get all the equipment for it. My questions are:
1)If I decide to use dumbells instead of bands, what range should I have? I currently have 3,5,8,10 lbs. Should I go up to 20 lbs or what?
2)I can decide if I should do weights and bar or just bands? Money is an issue too. Any opinions?
3)Has anyone used bands instead of a pull up bar? If so what do you think about it?

Thanks for all your help. Candi
