How Posture Affects Hormones – Flexion vs Extension | Boost Testosterone

I recently interviewed a long-time friend and colleague of mine, Scott Grisewood of Shockwave Therapy Centre in Barrie, Ontario, about the relationship of posture and movement patterns to our hormones, mood and physical performance.

How to Warm Up Properly to Improve Performance & Avoid Injury

An effective warm up can improve your performance in your workout or sporting activity as well as prevent injuries. However, some common methods of warming up may actually increase risk of injury and reduce your strength and performance.

For example, many people still perform passive stretches before working out, which can temporarily dampen the nervous system activation of the muscles you stretch and leave them weaker for a couple of hours. This not only reduces performance in your training session but can also lead to joint instability which increases risk of injury.

Dynamic Warmup

Another popular way to warm up is to run on the treadmill or hop on the bike for a long, slow, low intensity cardio session before hitting the weights. While there may be some benefits to a brief cardiovascular warm up, there is no need to expend a significant amount of energy doing cardio before training. There are more effective and time efficient methods for preparing yourself for a workout, such as a dynamic warm up and core activation isometrics. Continue reading

Slow the Hell Down! Fast vs Slow Velocity Training

We’ve all seen it … the gym rat swinging heavy dumbbells and calling it “bicep curls”; or rocking back and forth with the full stack on the lat pulldown; or bouncing a heavy bar off their chest on a bench press, pounding out some fast reps. There’s also those people who treat weight training like “cardio” – firing off dozens of reps at lightning speed with very light weight.

What do they all have in common? Besides the fact that most of them are probably injured in some way, they are are all performing their resistance training at a fast tempo.


Now I admit that I’m generalizing when I describe everyone who performs fast reps as “ego-lifters” with crappy form… there are many experienced lifters who practice decent exercise technique but train with a faster tempo. However, the point of this article is to question whether that is the optimal way to train. Continue reading

How to Fix your Feet – The Benefits of Barefoot

What if I told you that there is one neglected body part that you could strengthen which would lead to an increase in full body strength and mobility? It might not be what you expect.

I’m talking about your FEET.


If you suffer from foot, ankle, knee, low back pain, or related problems including shin splints, bunions, heel spurs, plantar fasciitis, ‘fallen’ arches, or Achilles tendonitis, then this article should be of particular interest to you. Your feet may be holding you back from becoming stronger.

The feet are the body’s base of support. During exercise, sport, and most daily activities, force enters the body through your hands and feet, with the feet supporting the bulk of this workload. However, whereas most people understand the importance of grip training and how strong hands contribute to a strong upper body, our feet are often neglected. Most people just shove their feet into rigid dress shoes or ‘bouncy’ running shoes and forget about them.

To make matters worse, when our feet start to hurt we are typically advised to wear rigid orthotics or “ultra-supportive”, inflexible shoes to help support our feet. Unfortunately, binding up your feet like this interferes with or even eliminates their ability to move. Less movement (or poor movement) leads to more weakness.

Orthotics are like crutches… they may take the pressure off while you are using them, but they do not correct the underlying weakness. If you had weak hands or sore wrists would you start wearing wrist wraps and rigid hand splints every day? I hope not. You would perform mobility and strengthening exercises to restore proper function to your hands. Well, your feet typically weight bear all day long, which makes it even more crucial to focus on strengthening their weaknesses rather than “bracing” them externally!

In this article I’ll be introducing you to exercises and footwear that can help you “fix” your feet, heal old injuries, improve your posture, and start moving better in general. Also take a few minutes to watch my recent interview (below) with Steven Sashen, barefoot runner and the founder of Xero Shoes® (a modern spin on the traditional barefoot running sandal), where he explains the problem with most “athletic footwear”

We discuss several important topics related to foot health, including:

  • The three key moves that let you easily and comfortably run barefoot
  • Why “minimalist” shoes are not the same as barefoot (so if you tried minimal and it didn’t work, here’s why)
  • How being barefoot can help if you have ankle, knee, hip, back, or even neck pain… and plantar fasciitis
  • The “foam mattress” theory about why cushioning and orthotics may be harming you. Continue reading

8 Benefits of Strength Training For Women

I wish all the women who are afraid that lifting weights will “bulk them up” would show me their muscle-building secrets! I’ve been busting my ass for years to gain a few more pounds of muscle mass! Where does this fear come from? Certainly not from personal experience.

Men and women need to approach their resistance training program with a similar intensity. Of course there will be small variations in each individual’s workout, but to get results both men and women need to participate in a challenging strength training program as part of their overall exercise plan.

Sciatica: Facts, Symptoms and Treatment

Are you suffering from sciatica? Know all about it here and find how to reduce your pain. Sciatica is defined as the pain caused in the lower extremity resulting from irritation of the sciatic nerve. The pain of sciatica is felt from the low back that is the lumbar area to behind the thigh and can radiate down below the knee. The root cause of this pain is irritation of sciatic nerve, which is the largest nerve in body. It begins from nerve roots in the lumbar spinal cord in the low back and extends through the buttock area to send nerve endings down the lower limb.

1.      Causes

While sciatica is most commonly a result of a lumbar disc herniation directly pressing on the nerve, any cause of irritation or inflammation of the sciatic nerve can produce the symptoms of sciatica. This irritation of nerves because of an abnormal intervertebral disc is referred to as radiculopathy. Apart from these reasons, other causes of sciatica include nerve irritation due to adjacent bone, tumors, internal bleeding, pregnancy, infections etc.

Will Crossfit Bring You Gains or Pains?

We’ve all heard the expression ” No Pain No Gain.” Unfortunately I’ve seen far too many people have more pain than gain as a result of this philosophy. Part of the problem with an overly aggressive approach to getting in shape is that once you are injured you will have set yourself back significantly.

As an example, let’s look at the popular yet somewhat controversial group fitness cult craze called Crossfit. Those who argue in favor of Crossfit insist it is a fun, effective, and intense approach to fitness that delivers fast results. Many believe it is also a terrific way to train for overall “athleticism”.


However, Crossfit has also gained a reputation for delivering more than it’s fair share of injuries as well. Part of the reason for this is the explosive nature of many of the exercises involved. Quite often, these fast movements are performed for very high repetitions with minimal rest between them. This can be a recipe for disaster. As one fatigues, exercise form tends to get sloppier, and when moving weights quickly in a fatigued state the risk of injury is much higher. Also, in my opinion many Crossfit athletes adopt a “don’t quit” attitude, which can lead them to push to the point of flirting with injury. This is when speed can kill.
