Dumbbell snatches are fucking awesome. Unlike barbell snatches, they take virtually (there are tiny nuances, but anyone can do them correctly within 5min of seeing it) 0 technique to perform. I've found they are best utilized for tonic or -10% (i.e. shittastic) training days, or as a maintenance tool while you are injured.
For tonic or shitty days
This is a movement you can do relatively heavy without any thought. I've found it does not matter much whether I am feeling strong or weak, I can still put up a decent amount of weight for highish volume. So on those days where everything sucks, consider DB Snatches.
A pretty common question I see floating around is: my ____ is fucked and the doctor says I need to be a pussy for the rest of my life. Answer: dumbbell snatches. These have helped to rehab messed up elbows and knees (not to mention they keep my shoulders happy). I can perform them with my groin tweaked and a herniated disc in my back (from the hang position, no biggie). They are not as useful for gaining strength and size as they are maintaining it. While this does not seem like hot shit, when you are injured it is a boon.
Going along with the theme - work around your injuries - give DB Snatches a shot, you will not regret it.
If starting from the hang position
Slight bend in the knees
Tension in the hamstrings and glutes
Arch your lower back, you should feel an isometric contraction in your lats. Use this as a shelf to pull the weight along with shrugging your traps
From the ground
About the same, you just have more time to use your legs to drive Ye weight up
Surgeon Generals Prescribed Sets/Reps
I prefer high sets with low reps 10-15x3 with as little rest as possible in between sets. Keep in mind this is sets per arm, not total.
Once I hit the largest dumbbells in your gym, I am going to elongate my sets by doing 2 rep clusters (hang snatch + power snatch = 1 rep).
