Row, row, row your back

When people check themselves out in the mirror, they tend to focus their attention on what is immediately visible. Their arms, their waist, their chest, their quads, etc. Some people will also do a little bit of twisting to see how their rear end is shaping up, but that's usually the extent of how much our flip-sides are examined.

If you're failing to do a vanity check on your back, that's OK. But if you're so unconcerned with how your back is shaping up that you don't work it properly during your workout, that's not OK at all. Even if you have no desire whatsoever to build a muscular back, you must still give it some attention. Otherwise, you will create a physical imbalance, therefore increasing the likelihood of injury.

To prevent this from happening, and to build a toned back in the process, try incorporating the bent-over dumbbell row into your workout. To do it, grab a pair of dumbbells and stand shoulder-width apart, with your knees slightly bent and your trunk at a 45-degree angle. With your arms fully extended -- holding a dumbbell in each hand -- contract your trapezius and deltoid muscles so that the weights track up along your body. Continue until the dumbbells are aligned with your collar bone, and then hold the weights in that position for one second. Finish by slowly lowering the weights until your arms are almost fully extended.

Here's a good video demonstration I found on how to perform the bent-over dumbbell row.
