Your friend is mistaken. For p90x you need either weights or resistance bands and a pull-up bar. Technically you can do the pullups with the bands, but you still need someplace to hook the bands (like over a pullup bar). You will want a mat for the ab routine and yoga and probably yoga blocks if you're not flexible. And a chair and towel for some exercises, but that's not really specialized equipment.
