I've been working on the basic FSPs and have been shuffling back and forth from WODs to Killroy templates on and off for a while now - but I'm positive I can't even do a cartwheel, let alone any moderately advanced moving elements. Where should I start to make progress in this arena? I feel like a cartwheel would be very useful for bailing sideways on handstands (which I currently can't do due to hamstring inflexibility). Flips would be cool too, but I don't have a gymnastics facility to train at - is it possible to learn this stuff by yourself in your backyard or something?
Thanks!
