So, What Was Being Targeted With the Diagonal Snatch, Log Uppercuts and Spirals??

Diagonal Snatch:
-In this exercise, you are moving the kettlebell in a D2 Flexion Pattern in PNF (Proprioceptive Neuromuscular Facilitation).  Basically, you were working a diagonal proprioceptive pattern which will lead to more efficient functional movement patterns (Targeting the Nervous System)
-You are working Shoulder mobility, scapular stability, grip, forearm strength, rotator cuff stabilization, core stabilization, glute activation

Long Log Uppercuts:
-More diagonal patterns, this time with speed and power, which is more challenging to maintain core stability
-Grip and forearm strength
-Scap stability as you do not want to allow your shoulder blades to protract while you are "punching" upward

Short Log Spirals:
-Diagonals again, this time combined with dragon lunges
-Do not allow the logs to move off of your forearm, so you must squeeze the handles tight (Grip)
-If you push off the rear leg when moving into the upright position, you get a dynamic psoas stretch and assist your push off which is necessary in many sports.  Obliques will also be targeted as your trunk rotates and the core must remain stable throughout
