Wall Ball Rehab!

My super simple and effective method of using a tennis ball (or Lacrosse ball) to reduce sore stiff muscles, rehab/pre hab, and improve mobility! Also mentioned in this vid and recommended, Joe DeFranco’s “Limber 11” and The Rumble Roller.

Testosterone And Spinal Cord Injuries (SCI)

In prior posts, I have discussed my hypothesis that growth hormone and related growth factors,  as a possible therapy for  connective tissue/joint degeneration in active populations. The study below finds testosterone therapy (TRT ) appears highly valuable treatment in SCI; to prevent the loss of skeletal muscle post SCI. These results do not surprise me in the least and why this is not a common therapy for people with SCI is a tragedy in my view. If you, or someone you know, has suffered a SCI, I highly recommend you send this info to your/their doctor and pursue this as a possible option. It’s important to note that testosterone deficiency is common after SCI, and according to the U.S. Department of Veterans Affairs SCI unit:

These findings confirm both a substantial population of men with SCI and with testosterone deficiency, and a significant association between testosterone level and severity of SCI. Measuring serum total testosterone levels should be included in standard screenings for patients with SCI…”

I can say, a very common report of those who go on TRT is a big reduction in general aches and pains in my experience, and again, it makes perfect sense to me. The future treatment of SCI will be the of  use various growth factors and other modalities (such as stem cell therapy) to re grow/re connect the spinal cord. That technology is much closer than people realize, but it seems the med/sci community very slow to pursue this area as quickly as they should. Obviously, this approach could be used to repair damaged nerves and other tissues far less challenging than repairing a severely damage or severed spinal cord.
Useful summary info from this study Effects of testosterone replacement therapy on skeletal muscle after spinal cord injury:

“The most important finding of this study was that TRT ameliorated the decrease in fiber CSA resulting from SCI. TRT also attenuated the slow to fast fiber type shift as well as the decrease in oxidative enzyme activity. To our knowledge, this is the first study to investigate the potential of TRT to prevent atrophy in SCI. TRT in aging sarcopenia and in other diseases with muscle wasting (for example, AIDS) results in favorable effects on bone, muscle size and strength in both low-average and hypogonadal men.19 Increases in muscle CSA were equal, if not greater in TRT only groups than in exercise groups without TRT.20 These data and ours for SCI both demonstrate a positive effect of TRT on muscle size without traditional overload…” Continue reading..

Two Dumbbell Ball “Anti” Twists for Core Strength and Stability

Most twisting ab exercises are TERRIBLE for your lower back…seriously. Any oblique work you get out of them is offset by the potential damage you can do to your spine with a loaded twisting movement.

The deep muscles of the core (the obliques and transverse abdominis) are best worked in an “anti-rotation” capacity…which means working AGAINST that twisting movement that is so damaging to the lower back.

That’s where this exercise comes into play…I call it a 2 Dumbbell Ball Twist, but in reality it’s a ball ANTI-twist. Continue reading..

Psychology 101 Of Weight Loss

Does Your Mind Stop You From Losing Weight?


It’s interesting to note;  the single most important factor to not just getting the weight off, but keeping it off, is between our ears. That is, how people approach the issue, psychologically speaking,  is an essential component of success. And yet, 8 zillion weight loss books and programs out there, and at best, this aspect of weight loss gets lip service only.

Many diet programs out there don’t address the psychological aspect of why people fail to be successful with long-term weight loss. However, quite a few studies exist that have looked at just that. In many respects, the psychological aspect is the most important for long-term weight loss, and probably the most underappreciated component. Continue reading..

Testosterone and Prostate Cancer – Bye Androgen Hypothesis, Welcome Saturation Model – Time For a Paradigm Shift

A long-held belief is that testosterone stimulates development of prostate cancer and/or accelerates its growth. This fear is the most common reason for doctors’ reluctance to prescribe testosterone replacement therapy, even in hypogonadal men [1, 2] , which unnecessarily deprives many hypogonadal men of clinical benefits.

This summary gives an overview of an in-depth review of current literature regarding the relationship of testosterone levels and prostate cancer, and the effect of testosterone replacement therapy on prostate cancer progression and recurrence.[3] Key studies which have refuted the old belief that testosterone has harmful effects on the prostate are presented, along the new testosterone-prostate paradigm known as the saturation model.

Surprisingly, new research provocatively suggests that it is not high testosterone levels that are problematic for prostate cancer, but to the contrary that it is low testosterone that is associated with worrisome cancer features and outcomes…and new experimental research has uncovered mechanisms that explain how low testosterone levels may be detrimental for prostate health, and support the new view that testosterone therapy actually may have beneficial effects with regard to prostate cancer…

Testosterone In WOMEN – is it physiological and clinically important?

EDITORS NOTE: A recent video I (Will Brink) did HERE  also discusses the fact T is just as important women as it is for men, yet continues to be ignored by most women and the medical community at large. Monica’s excellent article below give the full details!

Testosterone is popularly known as the “male” hormone. While it is true that men have much higher levels of testosterone than women, and that testosterone contributes to secondary sex characteristics that physiologically distinguish men from women (increased muscle mass and facial/body hair), this does not mean that testosterone isn’t important in women.

In the same way that men need estrogen, aka the “female” hormone, for optimal health, women need testosterone for optimal health. This article will describe testosterone physiology in women and its importance for women’s health, and refute the two prevailing myths that “testosterone is un-physiological in women”, and that “there is no research or clinical experience supporting the use of testosterone therapy in women”…. you may be surprised…!

The Skinny On Diet Supplements: Reviews


Book Review: The Skinny On Diet Supplements

By Rick Silverman M.D.

If you’re the kind of person who likes to have the inside scoop, the real deal, the down and dirty on any given issue, then Will Brink’s book, “The Skinny on Diet Supplements,” should be on your required reading list for nutritional supplement information. This book is an encyclopedia of dietary
supplements and their role in weight loss, looking at each item in an in-depth and organized way.

Each chapter focuses on a single supplement, cites what it’s supposed to do, and provides details of the science behind the product, including some dissection of that science. The next section looks at the “real world” chatter about the supplement, and that’s followed by the best feature of the book, Will Brink’s recommendations. This last feature is my favorite section in each chapter, because Will is not shy about saying what works and what doesn’t work. He isn’t beholden to any particular supplement or supplement company, so it doesn’t feel like you’re being sold a bill of goods.  Rather, he cuts through the falsehoods put forth by the supplement industry, and where evidence supports the use of a product and that product has proven real world results, he tells you so. Where evidence or the real world comes up short, he tells you that. Continue reading..

Your Foam Roller On Steroids!

The Rumble Roller Takes Soft Tissue Work To The The Next level


Like many people, I have my fair share of aches & pains, tight muscles, and hard earned small injuries and such. Like many,  I have been using a foam roller for soft tissue work or SMFR (Self-Myofascial Release) work to improve sore muscles, tight muscles, and general recoup.  I generally do my foam rolling in the morning for 15-20 minutes while the oatmeal cooks and coffee brews. It gets me ready for a day at the computer also. I also use it at the gym before workouts, a few times per week, and I find doing so reduces DOMS. Foam rolling is often referred to as  “the poor mans massage therapist.” In terms of time and $$$ spent, it’s a no brainer in terms of benefits you receive. If you’re not using a foam roller regularly, you should be, like starting yesterday!

Rumble Roller comes in two sizes and firmness

As time goes on, one notices the standard foam roller not as effective, and or, they start to break down, and a replacement needed. Some seem to last longer than others. Enter the Rumble Roller, which takes foam rolling to another level and seems to last far longer than the standard rollers. I was going to make one of my usual videos talking about the benefits of foam rollers, and why the Rumble Roller superior, but coach Charles Staley – who has some great articles here on the BrinkZone – did such a good job of it, I decided to use his vid on the topic. If interested in more information, I purchased both the standard length and shorter smaller (12″x 5″) travel length HERE

Personally, I prefer the standard (blue) firmness Rumble Roller. Highly recommended if you already use foam rollers, not recommended for those new to foam rolling for soft tissue/SMFR  work as the Rumble Roller is very aggressive. Watch coach Staley’s excellent vid on the benefits of foam rolling, and why he likes the Rumble Roller over standard rollers in particular.
