Abdominal crunches are one of the most common abdominal exercises, but at the same time are one of the most effective and simple. In this exercise you lay on the floor with your feet tucked to your body and knees pointing to the air. Then you simply raise your chest up to your knees. When completing this exercise, focus on the contraction of the lower abs to increase the intensity and strength benefits. Keep your hands by your ears during this exercise and do not pull them behind your neck because this may lead to neck strains. Complete in sets of three with 15 to 25 reps depending on strength levels.
Russian twists are an extremely powerful abdominal and oblique workout that can be beneficial to a golf swing. In Russian twists, you sit on your upper butt and very lower back with the upper back off the ground as well as your legs. You then tuck the legs in more towards the chest to contract the abdominal muscles and increase the intensity of the workout. Then with a medicine ball in hand you move your arms side to side touching the ball on the ground. This exercise targets the obliques as well as the lower abs. The movement of the exercise is much like the rotation of a golf swing and will increase power dramatically. This exercise can be done for three sets with 25 reps. If it becomes overly difficult, a medicine ball is not necessary.
Supermans are a simple exercise that develop the back muscles necessary for a golf swing. In this exercise you lay on you stomach and lift your legs and chest of the ground. This leaves your stomach on the floor and the rest of your body about 6 to 12 inches off the ground. When doing this exercise focus on the contraction of the lower back. Complete three sets for 10 to 15 reps.
