Hitting the ball from a downhill slope presents a few challenges and requires a few adjustments from your normal setup. Beginner and high handicap golfers have a tendency to hit these shots either fat or thin.
The first thing to do is to line up your shoulders parallel to the slope of the ground. Your lead shoulder will be lower than your back one, how much depending on the severity of the slope. This will put the majority of your weight on your front foot. Due to the slope, your weight will stay on your front foot during the whole swing. Attempting to place too much weight on your back foot is what contributes to hitting the ground before hitting the ball.
Hitting off the downhill lie will make your ball fly lower. This is because the slope is delofting
Aim a little bit to the left because the ball will go slightly to the right as having most of your weight on your lead foot will tend to make your body get ahead of the ball and will but a slight fade on it.
