Anyone know this drill? Two clubs and two balls?

[MRR]

Within the past two months, I saw a very interesting drill that I assumed came from one of my recent golf magazines, but now I cannot find it.

The drill involves taking two different irons (one in each hand) and swinging them.  This appears to be a standard drill to help with either action or timing.  What was added to this drill is placing two balls on the ground and hitting them at the same time.  If I recall correctly, one ball was placed a few inches farther away from the golfer.

 

Does anyone have any idea where I saw this drill?  My fiance recently cleaned up some of what she calls a mess and now my magazines are out of place or outright missing.

 

Thank you,

Thanks.  I thought my subscription ran out before that issue.

Guess I need to renew my efforts to find what has been lovingly misplaced.
