Grab a pair of dumbbells. Hold them with palms facing towards you.

Keeping your back straight and head in neutral stance, bring the dumbbells up and squeeze your back, exhaling on the way up. Bring your chest out and drop your shoulders back and squeeze them together.
Hold for a count of 2 and return to starting position slowly, inhaling on the way down.

 hence a neutral position of the head will be beneficial.
Keep your abs tight throughout the set, as it will help you keep your back straight.
