> >>> The load that Pujols and Reyes and others use seems to be good and easy to do. They just turn there front foot in, set it down, and then hit. Is this a good load? They dont really stride or anything, sometimes Pujol's does, but most of the time he will just turn the foot up and then turn it down. What are the key parts to doing this load correct? Is there anything you should really focus on? Thanks alot guys.<<<

Needless to say, he was dismissive, indicating one would "spin out" too fast if they attempted this. He argued balance is better maintained if the front leg merely rolls with the front hip in a reverse arc.

> To be honest, I have had very few students whose major problem is with their lower body mechanics. I spend a lot of time teaching the batter how to prepare good Launch and Contact positions (all the points shown in your training booklet). I have the batter address the heavy bag with the correct contact position. Then I have them use their legs (mainly the lead-leg) to rotate back to a good launch position (lead-heel up pointing toward third base). Then rotate around a stationary axis back to the contact position. This rotation is activated by the rotation of the lead-heel rotating back toward the catcher as it lowers and the lead-leg begins to extend. Then they rotate back and forth from launch to contact. Once they are fluid with their movements, they can start incorporating their timing step.

> I impress upon them that all swing mechanics (lower and upper-body) has one ultimate purpose – to accelerate the bat-head around the swing plane to contact. That is what they should concentrate on – not the legs or hips or accelerating the hands – Think, rotate the heel, rotate the bat-head. -- First in an arc back toward the catcher then around toward the bag. -- No tension, no explosion – loose, smooth, ever accelerating movements.

> The student’s bat-head acceleration seem to sync with hip and shoulder rotation better when thinking of accelerating the bat-head rearward than when thinking “hips first” or similar leg type cues. At least this is true for my teaching. --- This is the same method (and thought process) I used to teach John the basics of rotational transfer mechanics he exhibits in the video. John’s main problem was (like many others) his muscles were so tight from years of relying on linear mechanics, it took a long time to loosen him up to swing freely.

You are one of the biggest advocates and 'cue' users of the term 'torque'. Torque in rotation. You also state you come from a solid academic/scientific standpoint when it comes to the rotational swing. If torque is defined as two equal forces acting in opposite directions about an axis, I don't understand what the arguement is here. Equal but opposite. So I would conclude that both the front and rear leg/foot apply equal force. How the force about the axis is applied isn't that a personal style arguement? If baters are rotating the lower and upper body in the correct kinetic chain, applying torque at the wrists as the hands come around with the rear shoulder while maintaining CHP (my eye opener!) is it worthwhile to debate over how Pujols rotate vs. how an ARod or other batter rotates?
This endless discussion of each MLB batters' personal style is just so confusing. Can we somehow stick to the CORE mechanics explaing what is universal and where personal style can be applied at which points in the universal rotional movement.?
