The HANDS do nothing but hold on. (as a thought for you)

Hit divots as if the "ball" were at your front toe...see how forward you can get it...(as a drill for you)...(btw if you hit your irons low after this start with your head no more forward than center...and KEEP it back)

Another drill...

Learn to hit something with a towel in your hands (swing it like a club)......sustain the lag! (lol)

...

And all this is null if your clubface is rolled too open in the backswing....

...cause having Lag will do nothing for you but leave the face too open for even longer. (and it might make you shank)

Good luck.

Soon enough it'll be second nature. (with practice and good mechanics)
