The traditional split snatch is a great Olympic lift, but you might kill somebody doing it in a normal commercial gym with a barbell. Plus, a regular gym probably doesn't have the right equipment.
No worries, you can still get many of the same benefits by doing this dumbbell variation. This will develop unilateral leg strength and test your athleticism.
There's an old saying that goes, "Give a man a fish and feed him for a day, but tell him about periodization, and confuse him for the rest of his life."
