Hey Austin....
First, thanks for the deadlift video. That helped immediately get me into a better position for my deads.
Got any tips for developing explosive lateral movement. Doing Heidens now. I was curious about something similar to vertical jump training (Vertimax for example) just in the lateral plane.
Definitely, and I think this extremely important. Power development is usually plane specific which means a crazy good vertical jump does not always translate to improved throwing velocity.
I actually wrote an article for Stack.com on this very topic. You can check it out here:

It is also important not to neglect strength training in the lateral plane. Exercises such at lateral lunges and lateral db goblet step ups are fantastic for baseball players.
