Using the Swing Speed Training Aid is simple. Just hold it as you would a regular club and start swinging. Try to do this for a few minutes every day to gradually improve your swing speed. When using it, make sure your grip is firm to avoid the trainer slipping. Also, don't over - exert yourself as this could lead to muscle strain. As for maintenance, keep it in a dry place after use. Wipe it down with a clean cloth if it gets dirty. You can also check the parts regularly to ensure everything is in good condition. Remember, the weights need to be bought separately if you want to add more resistance to your training.
