Hi Batman
I have a big trouble. You see my arms, hands, wrists are so week that just a couple of days before i fell on my wrist and now it is fractured and it will get plastered. Tell me how i can improve my muscles. Reply soon
thanks
>>> I'm just curious: from what I gather from your information and Jack's tape, the key to batspeed is rooted in the hips. You seem to be saying that strong hands and arms are almost irelevant. For example, if you have two hitters with identical mechanics (upper and lower body), identical lower body size, lower body strength, etc, but if one hitter has stronger hands & arms, you seem to be saying that the one with the stonger hands and arms will NOT have an advantage. Do I understand you correctly? Thank you <<<

But, for the baseball/softball swing, having stronger arms and hands is much more important when using linear mechanics than it is with the rotational hitter. As we have discussed many times, linear mechanics rely far more on the hands and arms to bring the bat-head to contact.

The function of the lead-arm in transferring shoulder rotation into bat-head speed is similar to the function of the string when swinging a ‘ball on a string’ in a circle. The lead-arm and the string are not major factors in generating the energy, their function is mainly to transfer the energy from the source of rotation to the ball or bat-head. Therefore, having a stronger arm or using a heavier rope would have limited impact on the speed derived.

It flexes and supplies the pulling action for top-hand-torque during initiation and maintaining the “L” position to contact. But the effectiveness of this mechanic is more dependent on timing and rhythm than on arm strength.

But at the same time I would agree that a bigger stronger batter using the same mechanics could supply more energy and would therefore develop greater bat speed. --- I recommend not gripping the bat too tight, just tight enough to keep it from flying free. Your question seems to indicate that you feel strong hands play a bigger role in generating power – please explain.

> > Jack,I believe that the arms and wrists should be strong in a hitter but for different reasons than most i believe.First the arms must be strong enough to control the bat when all that energy starts going through them from shoulder rotation,the wrists as well. I sometimes feel a strain in my lead outer shoulder from the strong rotation I am applying with them.It seems to me you put more strain on the body because we are able to generate much more speed even when fluid with the mechanics.Therefore we need a strong overall body but also in the arms which are small muscles controlling all the energy of the big ones.Kind of a weakest link in the chain idea,but not that they add alot of energy to the swing.However the wrists I thought do add alot of batspeed through torque that is going on between them.In essence I think they are important to handle and control the energy going through them and the torque which the wrists help apply.
