Some of the most popular supplements today are the so called pre-workout nitric oxide (NO) boosters 1, 2. These contain a panoply of ingredients, but the main one is arginine. The rationale goes that arginine is a nitric oxide (NO) precursor and NO is a potent vasodilator 3, 4, which in turn supposedly will boost blood flow to exercising muscles, performance and recovery. And while arginine supplementation is beneficial for various clinical populations (see below), studies in healthy adults have not unequivocally supported the marketing hype surrounding arginine supplementation and nitric oxide boosters 1, 5, 6. Why? Let’s take a look under the hood…
The Bent-Over Lateral Raise is one of the most common exercises used for working the rear or posterior deltoids. For most trainers, it can be difficult to really feel the rear delts working during this movement as the larger, stronger muscles of the back have a tendency to take over.
To really get the most out of this exercise, you need to remove the back muscles from the equation. This can be easily accomplished with a simple technique.

For reasons that are not readily apparent, there appears to be a conservative political movement that opposes the use of testosterone in older men. This was clearly demonstrated by the report of the Institute of Medicine, which felt that testosterone is not yet ready for prime time and that there is still a need for studies to prove its efficacy 1. Along the same lines, the guidelines of the Endocrine Society on testosterone use in older men seem to be ultra-cautious 2 . But fortunately, there are also other, more liberal guidelines and recommendations 3-5.
Probably no other medical issue has been bombarded by the influx of “expert” views from all walks of life; from endocrinologists and psychiatrists to urological surgeons and gerontologists, from the lay press to the regulatory agencies and from the pharmaceutical to the entertainment industries. The dismal result of all this free-for all cacophony of opinions is a great deal of confusion, erroneous information and significant detriment to patients and physicians alike.
Let’s take an in-depth look at the reasons for the negative attitudes to male testosterone replacement therapy (I will cover post-menopausal testosterone replacement in an upcoming article), and the hard scientific data that refutes it…
Every experienced weight trainer knows that the proper way to breathe during a set is to inhale during the negative (lowering) phase and exhale during the positive (lifting) phase. But is this the best way to breathe in all exercises?
As a matter of fact, it isn’t. I’m going to show you exactly how and why you should breathe BACKWARDS during many if not most back exercises. I will use the lat pulldown exercise to demonstrate this powerful technique.
If you don’t have access to a seated calf raise machine in your gym but do have access to a lying leg curl machine, you can use it to do an excellent version of the seated calf raise. It’s most useful when your lying leg curl machine pad is a single straight padded bar rather than separate roller pads.
The chest is one of everybody’s favorite muscles groups to work…and the bench press, dip, flye and cable cross-over are the four major movement patterns used to work the chest.
The exercise I’m going to show is a variation of the flye and the cable cross-over…it’s essentially a cable flye. This is not something earthshakingly different, nor is the different method I’m going to show you for doing it.
Training the upper chest is extremely important for overall balance in the upper body, and it’s one of the most neglected aspect of chest training…usually for the simple reason that it’s harder and you can’t use as much weight. Now, for hitting those upper pecs, the Incline Barbell Bench is one of the most common exercises. If you’re like me, you have a hard time getting results from this exercise done with standard form…all you get are tired triceps and sore shoulders.
If so, I’ve got the solution for you. It’s a very simple adjustment to the setup that you use for the incline barbell press and an adjustment in how you perform the exercise.
Consumption of red meat has been associated with fat gain (and weight gain) because of its high energy and fat content. Even though the role of fat intake as a causative factor for obesity recently has been seriously questioned, and rightly so, red meat still is a food that’s on the forbidden or avoid list of most diet plans. And while there are studies showing an association between meat intake and obesity [1-3], there are also studies not showing this [3-5]. And when digging deeper in the data, many of the studies that have reported a significant association with meat intake and fat gain / obesity have several flaws that invalidate their conclusions….
Recent studies have shown some controversial findings that high-rep training is as effective as the traditional medium rep training for muscle growth. If you missed it, check out my two previous articles:
In this article I will show some examples of how high-rep sets can be implemented in a serious weight lifting program, and look at the results of some studies that have investigated this.

Dr. Chiang runs Northeastern Chiropractic is a regular contributor to the BrinkZone and has written several articles – with more to come – on topics such as rehab and injury prevention for the shoulders and other body parts that tend to cause problems for active populations. As you will see, Dr. Chiang knows hard work in the gym, so he can relate to athletes and active people who have various aches and pains. He’s the guy I see for my aches and pains! The other day I took my camera to Gold’s Gym and got him hitting the Prowler sled with some serious weight!
