Trying to hit the ball as hard as you can will rarely give you golf swing power or the desired long drive. More often than not, you will note that the ball ends up going disappointingly close rather than further. In fact persistent efforts to hit the golf ball as hard as you can, will most likely end up giving you golfers elbow as you strain your unprepared muscles to achieve the desire of your heart.
There are two main reasons why this approach does not work in helping you achieve golf swing power. Firstly golf clubs have all been cleverly and specially designed to fulfill various tasks. And within those clubs, there are several that will help you gain various degrees of golf swing powered long drives.
This is the reason why use of physics in this situation (that is the right technique so that you hit the ball at the right angle and in the correct way to gain your long drive) works much better than brute force.
Secondly there is an amount of strength and power that needs to be applied. This can only come from muscles that have been strengthened and condition to achieve consistent golf swing power.
The real secret behind effective golf swing power is golf-specific exercises that help you to use your spine correctly as an axis to promote consistency in your drives and to keep you focused on the correct swing play. Only this can give you true golf swing power and much longer drives on the course.
