US Patent 11918879 Golf swing trainer

There are numerous tools a golfer can buy that will increase or decrease the weight or moment of inertia of a club to increase swing speed, but none of these tools accurately represent the center of mass of a standard golf club. The differences in the center of the mass between the standard club and the trainer club can create problems with the swing including improper alignment of the club face through contact and improper swing path. A swing trainer that increases or decreases the moment of inertia of the trainer by 10-12% while still maintaining the same center of mass as a standard club can solve this issue.
