1. What is it and where does it come from?
Chromium Picolinate is thought to be the best source of chromium. Chromium is a trace mineral that is essential to the body's production of insulin.
Insulin is a hormone that stabilizes the body's blood sugar level. Brewer's yeast is considered the best source of chromium; however, foods such as corn-on-the-cob, buckwheat, apples, beets, tomatoes, wheat germ and bran, and sweet potatoes are excellent sources as well. Bodybuilding.com provides high quality chromium supplement.
2. What does it do and what scientific studies give evidence to support this?
Research shows that chromium is an essential part of our diet. Chromium picolinate can have many beneficial results when supplemented. It enhances insulin's effect in the body, improving the uptake of glucose, thereby causing better blood circulation and maintenance of blood sugar level. Gaining energy, burning fat, and building muscle with greater ease are attributed to chromium, to name a few. It assists the body in losing weight by helping it to build muscle to replace fat. Lowering body fat and increasing lean body mass are just a few of the positive properties that chromium picolinate exhibits on the body. Whoa, that is powerful!

3. Who needs it and what are some symptoms of deficiency?
Specific people have been shown to dramatically gain from ingesting chromium picolinate. Research indicates that the majority of people in the United States are chromium deficient. Most people could use chromium in their diets. As chromium levels decrease with age and deficiencies occur with people who do not eat a good balanced diet, chromium picolinate supplementation can be very beneficial. Because processed foods have much of the chromium removed, increasing ones chromium content is recommended to sustain proper glucose levels and gain energy. Anyone who likes to live with energy, burn fat, and increase strength and muscle mass would also do well to supplement with chromium...bodybuilders, that's you!
4. How much should be taken? Are there any side effects?
Research and most literature suggest supplementation of between 50 and 300 mcg to compliment a 2,000-calorie diet is adequate. When taken in such doses, chromium picolinate has not been shown to cause toxicity in humans.

Back Development
Back development is a key ingredient in the physique of a bodybuilder. One's back is what makes their upper body look enormous and their waist look tiny. The difficult part is finding a program that will develop your back in all areas. This article will discuss my ideas pertaining to building the back in terms of width, thickness, and form.
ANATOMY
The back is a complicated and multi-layered part of your physique. The outer, or visible part of your back consists of the upper, middle and lower trapezius, posterior deltoid, teres major and minor, and the external abdominal oblique. The deeper layers consist of the rhomboids and the erector spinae. This is of course not an all-inclusive list but is sufficient for the purpose of this article.
BACK WIDTH
The width of your back is determined but the size of the latissimus dorsi and the teres major. These are the muscles that are most prominent in the rear lat spread pose. But keep in mind that your lats are displayed with front poses like the front double biceps pose, front lat spread, and abdominals and thighs pose.The exercises that most effectively target these muscles are lat pull downs with a wide overhanded grip. This will hit the upper portion of the lats as well as the teres. You can modify this exercise by using a narrow underhand grip. To hit the lower portion of your lats I suggest doing bent-over bar rows with an underhanded grip. Just make sure you are at approximately a 30 angle from being completely upright. The final exercise I would suggest for this portion of your back would be pullovers either with cables or with a dumbbell.
BACK THICKNESS
Back thickness mostly depends on the size of your erector spinae, middle,lower, and upper trapezius, and posterior deltoid. The posterior deltoid really adds to back thickness front a side position because it makes your overall physique look thicker. Developing this part of your back is perhaps the easiest as far as number of exercises but also the most difficult due to amount of weight needed to stimulate the muscles. Some exercise suggestions for back thickness would be deadlifts, seated cable rows, t-bar rows, hyperextensions, and reverse flyes. For these exercises you really need to focus on high poundage repetitions using compound movements. Compound movements are those which involve numerous muscles in order to balance and support the body during the movement. These exercises also happen to have the highest potential for injury secondary to large muscle groups moving large amounts of weight. Be sure to warm up properly and use perfect form for the deadlifts or you will pay for it in the morning.
EXERCISE FORM
I tend to be a little more lenient when it comes to form on back exercises (with the exception of deadlifts). This is due to the fact that for each exercise you perform you are using more than one group of muscles. The primary muscles are assisted by additional muscles which serve to stabilize your body to properly perform the exercise. These additional muscles are called secondary or stabilizer muscles.
For example, during seated cable rows you are using middle traps, rhomboids, paraspinals, posterior deltoids, and lats. So in order to get the best bang for your buck cheat a little. When I say cheat I am referring to leaning forward approximately 45 before pulling the weight. To finish the movement bring the handle right to your belly button and bring your chest up. This will really help to involve all the groups of muscles.The idea behind this practice is to recruit as many muscles as possible during one movement. It is very difficult to isolate one muscle during most back movements due to the secondary stabilizer muscles.
