Training for a bodybuilding competition requires a systematic training program that includes daily strength training workouts and a strict nutrition plan. Each element of the training program plays a vital role in your overall appearance and success at the competition. A major component to your overall score is vascularity -- the visibility of your blood vessels underneath the skin. While the best bodybuilders have superior vascularity, you can also improve your vascularity through proper training, nutrition and hydration.
Follow a strict nutrition plan for four to six weeks before the bodybuilding competition to burn excess body fat while maximizing muscle mass. Daily protein intake should be about 1.5 g of protein per pound of bodyweight with carbohydrate intake around 2 to 3 g per pound of bodyweight.
Drink enough water throughout the day. Dehydration decreases your vascularity by filling the skin with water. Aim for at least 1/2-oz. of water per pound of bodyweight each day.
Perform cardiovascular exercise three to four times per week, 30 to 45 minutes of high-intensity cardiovascular exercise per workout to maximize fat burn without losing any muscle mass. Sample exercises include running, cycling, rowing or swimming as these act to increase blood vessel capacity while decreasing body fat.
Use a combination of supersets, drop sets and a high number of repetitions to achieve bigger muscular pumps in weight training. For supersets, perform two to three exercises in sequence with little to no rest in between. Drop sets are characterized by decreasing the number of repetitions per set while increasing the amount of weight. For high repetition sets, perform 10 to 20 repetitions per set. The pumps result in an increased blood flow to the muscles for improved vascularity.
