To develop a V shape like Peter Andre you need to build the lats (The wings under your armpits) and reduce the body fat around the waist.

1. Barbell bent over rows 3x 8-12
Hold the bar with an overhand grip with your feet shoulder-width apart. Keep your back flat and unlock your knees. Now bend forwards at the hips keeping your back flat until your back is 45 degrees to the floor. Pull the barbell to your waist and then lower to the starting position under control.

Alternate with

Dumbbell single arm rows 3x 8-12
Start with your right foot flat on the floor and your left knee resting on a flat bench. Then lean forwards so you’re supporting the weight of your upper body with your left arm on the bench. Reach down and pick up a dumbbell with your right hand. Look straight ahead in order to keep your back straight. Concentrate on pulling your elbow as far back as it can go. The dumbbell should end up roughly parallel with your torso. After you have “rowed” the dumbbell up as far as you can, slowly lower it to the starting position. After you complete the planned number of reps for your right arm, follow the same instructions for your left.

2. Abdominal crunch 3x 15-25
Start by lying with your knees bent at a 90 degree angle. Gently position your hands behind your head to support it. Don’t lock your
hands! Focus on contracting your abdominal muscles, curl the shoulders up and forward, until the upper back lifts off the floor. Imagine you’re trying to make a dent in the floor with your lower back, and let that contraction pull your shoulders off the ground. Hold the contracted position for a second before.

Alternate with

Abdominal bent knee raises 3x 15-25
Sit on the edge of the bench with your body at a 45 degree angle and your hands holding the nench for support. Start the exercise with your legs straight. Slowly bring your knees up to your chest while maintaining the position of your upper body. Do not be tempted to move your upper body towards your knees.

Advanced trainers can add overhand pull ups to the chin 2x max with bodyweight. Once you are
able to do 12 reps with your body weight you can start adding weight. This can be done by using
a dipping belt. They can be purchased cheaply from www.pullumsports.com
