If you want to tighten up your chest area, try a combination of resistance training and aerobic exercise. Working out with machines or free weights helps bring definition to your pectoralis, or chest muscles. Engaging in cardiovascular activity burns calories, helping you shed fat, which covers your chest muscles. Before starting a fitness routine to develop a flatter, more defined chest, consult a physician.
Lie on your back on a flat bench, with your feet place flat on the floor. Grasp a barbell with a medium-width grip and lift the bar from the rack.
Press the bar upward until your arms are fully extended.
Lower the bar until it touches your chest, keeping your back straight. Press the bar upward, focusing on flexing your chest muscles throughout the movement.
Do four sets of 15 repetitions with a light weight to develop a flatter chest. Rest for 45 seconds between sets.
Grasp opposing high pulley handles of a pulley station. Stand facing away from both pulleys, in the middle of the station.
Keep your elbows, hips and knees bent slightly. Move your elbows back by rotating your shoulders inward.
Pull the cable attachments together by making a wide arc with your hands, similar to a hugging motion. Keep your elbows fixed through the movement. Slowly return the pulley handles to the starting position.
Do four sets of 15 repetitions to get lean pecs. Rest for 45 seconds between sets to ramp up the intensity of your workouts.
Incline Dumbbell Flies
Lie flat on a bench set to a 45-degree incline. Grasp two barbells. Rotate your shoulders inward and maintain a slight bend in your arms, keeping your elbows pointing out to the sides.
Bring the dumbbells together in a hugging motion until the weights touch. Slowly return to the starting position, feeling a stretch in your chest muscles.
Tone your upper chest muscles with this movement. Do four sets of 15 repetitions and rest for 45 seconds between sets.
