the key with anything is do not over do any one movement.

I used to do a "cardio" day with an 8kg that consisted of

40 alternating hand swings
20 clean and press each hand
20 high pulls each hand ( you didn`t mention this drill - if you don`t know it - look it up - it is the easy precursor to a snatch )
20 snatches each hand
40 true snatches
40 two handed swings

2 min rest - repeat through 3 times

that will have you pouring sweat in no time

to help your TGU - break it down - keep doing the steps to the point before you stand as a drill for a while
keep your eye on the bell at all times - looking forward or down will cause you to loose stability
do the get down stage first - it`s easier than the get up

do lock out hold / walks - ( clean ..press .. hold for 30secs once you have the holds down - start walking with bell locked out - always watch the bell )

snatches will help your upper body so keep working on them

things to consider adding - windmills - high and low weights
farmer carries

Do not be afraid to mix the weight you use of different days - I am training to compete - the snatch is my event - 20KG bell - but I`ll train with everything from 12 through to 24 KG

everyone is dominant on one side - at my last event I think I did 77 snatches on my right and 59 on my left - some of that can be attributed to general fatigue but my left side is weaker than the right - On saying that my form is generally better on my left side because I can`t muscle is so easily ! That is the great thing about kettle bells they did help even out the left / right strength

When you start doing snatches wear a wrist band - it will help a little with the bell landing until you get the form right so you are not smacking your wrist - it really is my favorite of all KB drill - I think it looks so bad *kitten* once you work up to heavy weight - and it really is such a power move but so elegant when performed well. If you can do a high pull to turn that into a snatch all you do is release your grip slightly at the high point where the bell stops moving for the moment and slide your hand through the handle a little deeper and shot it up - go outside on some grass or sand and don`t be afraid to drop the bell - the first time I snatched a 50lb bell I actually locked the weight out and then lost my nerve and dropped the thing !! - they don`t break - I actually dropped the 45lb bell at the end of my set last weekend in the gym - sweaty hands - 117 reps in ! - lol.Not sure about the DVD you are using I have never seen it - but Iike the way Jeff Martone explains the progression - http://www.youtube.com/watch?v=9FrUqUPO284 - Don`t be afraid to dig through youtube videos of people like Mike Mahler, Martone, Steve Cotter - these are the old school KB guys who were doing videos before Walmart started selling pink bells !!

There are many ways to execute a snatch - there the normal "hard" snatch form which you are likely familiar with - a long swing arc - then there is the rectilinear form which is tighter and the bell travels more parallel with your body - rather like a clean that keeps going - and then there is the competition form with has a tighter more diagonal swing trajectory - then intent being to minimize effort to last for 10 mins / higher reps - with each there are subtle differences and you have to find your groove - some people like a slightly staggered stance v squared up - some prefer a slightly diagonal trajectory - if you look at a couple of people you will find the right form for you

Thank you! I just experimented with kettlebells for the first time today and loved it.
