In this video golf lesson, PGA Professional Peter Krause addresses a problem that many golfers experience, which is the inability to properly square the clubface at impact.
According to Krause, this happens because most golfers come at the ball too steeply, forcing them to fall back and add loft in order to avoid hitting the ground. Rounding off the backswing for a flatter arc on the downswing easily solves this problem.
The correct swing will finish with the back of the left hand facing the ground with the palm facing upwards. Properly squaring the clubface at impact will make the swing much smoother for better results.
