With some instruction and creativity, one kettlebell can go a LOOOOONG way! I've been using them since 2003 and a certified instructor since 2009 and always try to spread the word so to speak. In my normal workout right now, I only need one but I cycle to where I might use 2 kettlebells of 2 different weights. For around $250 you could do the same very thing and be set for a very long time.
Dragon, would you consider this a good routine for beginners?

I just started using kettlebells and I really enjoyed it.
