MAKE A STRONGER PIVOT AROUND YOUR FRONT LEG
Most amateurs I play with don’t have enough swing speed to power the ball out of the rough. They need more loft, so a 5-iron is probably not a good club selection. They also need to get their weight more on the front foot as they swing down. For me, that’s the right leg. For righthanders, it’s the left. The death move is to try to lift the ball out by swinging off your back leg. That puts too much grass between the clubhead and the ball. Instead, as you swing down, feel like your front leg is a super sturdy post, and pivot your body around it. This will produce a more vertical swing path to hit the ball solidly. Expect it to come out lower with less backspin.
