The back is a very important, yet often overlooked muscle group. Many people focus on training their "mirror muscles" -- the chest, biceps, shoulders and abs -- and neglect their backs. This can lead to poor posture, muscle imbalances and injuries. A well-developed back can also make anyone from a casual gym goer, right up to a professional bodybuilder look more sculpted, stronger and more muscular.
Grasp a chin-up bar shoulder width apart with your palms facing towards you. Start with your arms fully extended, and raise your chin towards the bar by squeezing your shoulder blades together and flexing your arms. Keep pulling yourself up until your collar bone is touching the bar, then lower yourself under control until your arms are fully extended once more. Perform four sets of eight repetitions in every back workout. Once four sets of eight is too easy, you can add weight with a dipping belt or by holding a dumbbell between your ankles.
Face pulls mainly train your upper back - the rhomboids, and lower and mid trapezius muscles. They are also a great exercise for correcting poor posture, which is often caused by weak upper back muscles. Set a cable pulley at head height and attach a rope handle. Start with arms fully extended, and bring them towards you by contracting your upper back muscles and flexing your arms. When the handles are in line with your face, slowly straighten your arms again. Do three sets of 15 reps every time you train your back, and add them in on rest days if your posture needs improving.
Designed by bodybuilder John Meadows, Meadows rows target the lat and rhomboid muscles. Grasp a dumbbell in one hand with your palm facing inwards, and put your other hand on a dumbbell rack to support you. Walk your feet back until your back is straight and parallel to the floor. Start with the dumbbell on the ground, and forcefully bring it up so it touches your lower chest, then return it to the ground. Aim for four sets of 10 reps per side.
A basic exercise to train the lower back muscles is the rack dead lift. Place an Olympic barbell across the pins in a power rack set at knee height, and grasp the bar with a shoulder width grip. Bend your hips and knees until your upper shins are in contact with the bar. Keeping your back straight and head looking up, lift the bar by extending your hips and knees and standing up straight. As this is quite a demanding exercise, only perform it in alternate back workouts, for five sets of three reps.
