Greater distance is achieved by a combination of strength and flexibility training more distance especially for those of us over the age of forty. If you strengthen your legs and arms you will be able to create more power and flexibility will help you to maintain the length of your swing, the amount of coil you can create and retain plus you will also develop better balance which will all add to an increase in club head speed.
To create stretch, resistance, coil and recoil that will generate additional club head speed, a golfer needs to have flexibility in his/her swing and in the majority of cases I see, this is lacking. The good news is that this can easily be rectified with consistent flexibility training and can lead to an increase of 20-30 yards additional carry from a well struck shot.
Flexibility is one of the most important aspects of a successful golf swing. The more flexible you are, the better you will be able to pivot your body that will help you to strike your shots further and straighter. Golfers that exercise regularly hit their shots further because they can have a longer backswing whilst maintaining good technique by creating a greater coil and recoil action.
Flexibility will help you generate more power
As you wind up your backswing your muscles are stretched to generate coil and leverage which is then retained (or even made greater) in the transition from backswing to through swing before releasing the energy through impact to maximise your club head speed through impact. The more flexible we are, the greater our ability will be to produce leverage and power in your downswing. Flexibility training will help you to achieve greater distance but be careful as you do not want to force your swing or risk injury.
