How to Hit a Homerun in Softball
To most hitting authorities, getting "full extension of the arms" and "how to hit a homerun in softball" appear to be synonymous. Invariably, when a long homerun is hit during a softball game, the commentator will say: "Wow, she really got her arms extended on that one." Linear hitting coaches also teach swing mechanics that rely on the extension of the arms. However, rotational coaches disagree. They believe homerun power comes from mechanics that keep the hands back and allow body rotation to swing the hands.
Batting Drills for Homerun Power
As pointed out above, batting coaches have varying opinions on the batting drills that generate homerun power. So what batting drills should a batter choose to maximize their chance of hitting a homerun? When in doubt, I suggest relying on the mechanics exhibited in the swings of the games top homerun hitters. With that in mind, Batspeed.com performed a frame-by-frame analysis of softball's top homerun hitters' mechanics.
The video below shows the swings of the homerun hitters we used in the analysis. These great hitters not only hit with power, they also had some of the highest batting averages.
VIDEO
What is common amongst softball's top homerun hitters:
The forward movement of the body stopped at heel plant and the batter begins rotating around a stationary axis;
The bend in the batter's lead-elbow remains constant during rotation to contact;
The back-elbow remained back at their side in an "L" position at contact;
The hands were rotated into a circular path; and
The arms did not extend until after contact (the ball had left the bat).
The hitting mechanics outlined above rotate the hands in a circular path and applies torque at the handle. These are the mechanical principles that generate homerun power and bat speed. For more information on why these mechanics are highly productive, read the following link. Softball Hitting Mechanics . The video below explains why the top homerun hitters rotate rather than extend the hands.

The Importance of Torque in the Softball Swing
Batspeed.com article, Drills that Increase Bat Speed , defines and explains the importance of torque in the swing. To apply maximum torque, the bend in the lead-elbow must remain constant from initiation to contact. To attain maximum acceleration of the bat approaching contact, the bottom-hand should apply a rearward force on the handle as the top-hand applies the forward force. If you maintain the bend in your elbow, the rotation of your lead-shoulder back toward the catcher will provide the rearward pull needed to apply maximum torque.
Below are a couple video clips that show these mechanics better than I described them. Although the videos features MLB hitters, the principles discussed apply to the softball swing as well. -- Note that in the "Bonds/Burrell" clip, their lead-arms are being pulled rearward rather than extending forward.

Requires more than a single view point

Bat drag - Without THT, bat rotation does not stay in sync with body rotation

Is hips leading the hands due to sequential timing?
Load causes separation -- No load = one-piece-swing (no separation)
Role of hips - Does maximum separation equal disconnection?
Separation/unison - Bowling ball analogy
Pulling head out - Premature rotation & no separation
Why not maximum separation - The 3 step swing (1-2-3)

3. ROTATIONAL HITTING MECHANICS
A. Initiation
Focusing on the whole swing - Not just forward movements
Envision the bat's rearward trajectory
Subconscious mind will set up a motor program
Its CHP/THT/BHT - But you can't think your way through the swing
Sync body rotation to bat-head rotation
Think: Rotate heel, rotate bat head
Obtain your optimum contact position
The mind will provide a motor-program to accomplish the body trajectories you envision
Don't "explode" - Think smooth ever accelerating power
B. Back-arm & Extension
"L" position at contact - Few average hitters attain correct position
Elbow to the belly button - not remaining in the "slot"

Is casting bad?
Linear theme: All straight movement is good, all circular is bad
Does barring = casting?
If so, does not "casting" = circular hand path
