Don't 'follow through', at least until after you've stopped the rod firmly.
What you described seems like the dreaded tailing loop. Poor application of power (too much too soon in the stroke0 a concave rod tip path... there are any number of reasons but the one I see most is poor power application. If you feel you must power the rod, do that as near the end of the stroke as you can. Try slowly accelerating to max speed at the end of the stroke then a crisp stop and see if that doesn't help.
