Mike Malaska introduces the M-System Lite M1: Line of Compression.
Line of compression goes right into the concept of impact. To hit the ball solid, you need to compress it, which most amateurs don’t. This happens because they don’t have a great line of compression.
What is line of compression? If you take a baseball bat and hit something, a tree, for instance, your arms will line up with the bat. This is because the bat stabilizes the force coming back through it.
Mike says that you wouldn’t roll your wrists when you hit with a baseball bat. If you did this in golf, it would be considered an ‘over the top’ swing.
Mike demonstrates what line of compression is with a baseball bat.
Line of compression happens in tennis too. If you take a tennis racket and make a forehand swing, the same thing happens. Your arm lines up with where you hit the ball on the racket, and this stabilizes the force.
In golf, line of compression starts with your putter. It is important to get a feel for it with putting and distance. You need to establish line of compression first with putting before you can master it with your full swing.
The concept of line of compression relates right to impact, and understanding it will help you.
Mike holds his putter level out in front of him so that his arm lines up with the shaft. His arm is slightly angled, a little forward, because his arm pushes the putt.
Some people keep the angle in the wrist, and others let it go, but the arm still lines up with the putter.
Mike now sets up to a ball with a line on it. The ball needs to roll the line. You don’t want the ball to wobble. You want a center face hit with a good path.
Mike demonstrates putting the ball as his right arm pushes the shaft through the ball. Again, the key is to make the line on the ball roll. Mike sinks the putt.
It is important to command line of compression first with just one arm so you are stable with the putt before you add your second hand and arm.
Mike moves to the edge of the green to talk about how line of compression relates to chipping. He explains that chipping is really ‘off-green putting.’
Line of compression is the same with chipping. You can see this as Mike lines up his arm with his wedge. It is on the back of the shaft and pushes the shaft through the ball.
You don’t want your arm to twist over or underneath. Again, you are pushing the shaft through the ball.
There is one change from putting to chipping, though. Mike has drawn a dot on the clubface. The key here is to put that dot on the back of the ball when you hit it.
The ball will get in the air, not because you lift it, but because the loft of the clubface gets it up. Mike reminds us that chipping is a ‘lofted putt with a chipping stroke.’
When Mike sets up to the ball, he likes to practice with just one hand/arm first and then move on to both. This is all about feeling the line of compression and how your right arm pushes the shaft through the ball.
Mike reminds us that the line of compression starts with putting and chipping. Then, you learn to compress the ball and get it in the air with the club.
This is a big concept to master, and it applies to every iron and club in your bag, including a full swing with a driver.
