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.
One of my favorite books is A Book Of Five Rings by Miyomato Musashi. Musashi was a badass 17th century Japanese swordsman who never lost a duel in over sixty fights. This book outlines his philosophy of success. I re-read it recently and was amazed by how many of his principles apply to a variety of areas in life, including productive strength training.
