Weight training can help
improve running performance and decrease risk of injury. It is easy to get in a routine and stick to
that routine without any deviation.
However, sometimes change is for the better.
Strength training has a lot of benefits that transfer
over into our running ability. Typically
people correlate their VO2 max, the maximal amount of oxygen the body can
utilize while running, with a high level of running ability. Being a competitive runner is not just about
VO2 max. Paavolainen proved this in his
study published in the Journal of Applied Physiology.
Paavolainen and colleagues proved that explosive strength
training increased 5k speed as well as improved running economy without a
change in VO2 max compared to the control group. They concluded this study by saying the
change was due to improvements in neuromuscular characteristics (Paavolainen,
Even if running competitively is not your goal there are
other benefits to strength training.
Running is a sport with a high amount of injuries. Strength training can help us avoid these
unwanted injuries and keep us training longer.
One way in which strength training can decrease injury potential is
through increased hamstring flexibility.
Hartig and colleagues showed that increased hamstring flexibility significantly
decreased overuse lower extremity injuries in military basic trainees (Hartig,
1999). You might then ask, “Can’t I just
stretch my hamstrings then?”
In some cases simple hamstring stretches may be
effective, but in a lot of cases it will not be. Tight hamstrings can be caused from a number
of different issues. Our glute medius is
responsible for controlling our femur (thigh bone). If this muscle is weak and our knees collapse
inward upon impact while running, our body will have to adapt and find a way to
stabilize the knee joint to try and avoid an injury. One way our body will adapt is by tightening
the hamstring. The hamstring crosses
over the knee joint and when tight may be able to supply some stability. The hamstring may also be tight in this same
case due to the weakness of the glutes in an attempt to provide more stability
at the hip joint. If running continues
in this state it is only a matter of time before we experience pain, more than
likely in the front of the knee. Simply
stretching the hamstring in these cases does not fix the underlying problem and
the hamstrings will remain tight (Sahrmann, 2001).
Getting into the gym and having a qualified professional
assess your movement is the starting point.
This can help identify weak areas and help develop a program to correct
them. Anyone taking up a running program
I encourage to do this. Identifying weak
areas and correcting them can significantly reduce injury risk as well as
increase performance through more efficient movement.
To summarize: to improve our running
performance and decrease the risk of injury, seek a qualified professional and
have your movement screened first. From
there any potential problems can be addressed through corrective exercise. Try changing up running every day to 2 days of
strength training, one day of intervals, and one day of steady state
running. I will guarantee you will be
amazed by the results.

I frequently get asked my opinion about the latest fad diet
book to hit the shelves. And before I
write anything further I should state that I do not think all diet books are
the same. Some have scientific merit
while others offer little more than anecdotal evidence from a genetically
blessed Hollywood star. But my general
take-away about fad diet books is that most of them offer eating plans that are
not sustainable for most people. First
off, the modern idea of a diet is a flawed concept. A diet implies a relatively short time period
during which someone radically changes what they eat, how much they eat, and or
how often they eat it. Now, I have stood
in line behind enough people at the gas station buying high calorie processed
snacks that hardly resemble real food, to know that some people need radical
change in their diets and lifestyles. So
how's this for a radical change…do the basic things well! Adopt sound lifestyle habits that are healthy
and sustainable over the long haul. Here
are some examples:
- Eat a balanced diet consisting of high quality
- Focus on smaller portion sizes at lunch and
- Eat breakfast every day within 45 minutes of
- Get a minimum of 7 hours of sleep each night
- Add small nutritious snacks at mid-morning and
- Exercise 3-5 days per week
- Limit consumption of grain based carbohydrate
- Limit consumption of processed foods
- Drink more water and eliminate high calorie
- Eliminate artificial sweeteners and flavorings
- Stay active, even on non-workout days
- Floss your teeth at least once per day
I am not suggesting that doing these basic things are easy,
they will require planning and discipline, but if you do them and make them
habits you will never need a fad diet book.

Since my early twenties I have heard a familiar refrain from
elders dismayed by their slow march towards physical decline… “Just wait until you hit forty, after forty
everything goes downhill.” But this concession to the perceived inevitability of
the negatives effects of aging has always bothered me. Now don't get me wrong, I am not naïve to
the physiological changes that occur in the human body as it ages, however I do
not subscribe to the notion that all of the negative changes are inevitable. Let's take a look at a couple of the most
common complaints people make about aging and see what can be done to mitigate
and/or eliminate them:
When I was a teenager
I could eat whatever I wanted and never gained a pound. Now my metabolism is considerably slower and
I have put on 5 pounds a year for the last 5 years.
If I had a dollar for every time I have heard this one over
the last 14 years I would be independently wealthy. First, changes in metabolism do not have to
be permanent and are almost always precipitated by a change in a person's
activity level. When you eliminate
disease, metabolic rates are cause and effect, so the reality is you have
probably slowed down from your hyperactive teenage years and your metabolism followed
Secondly, we start to lose muscle at an average rate of ¼
per year if we fail to do something about, i.e. strength training. The problem with this as it relates to
metabolism is that muscle is our most metabolically active tissue and helps us
burn calories faster.
What to do about it…
- Eat breakfast every morning! Breakfast should be consumed within 45
minutes of waking up and should have a balance of protein, quality
carbohydrates, and healthy fats.
(specific food choices will be outlined in subsequent posts)
- Eat every 3 to 4 hours. Your dietary day should look like this:
breakfast, mid-morning snack, lunch, mid-afternoon snack, dinner. If weight
management is an issue, snacks should not exceed 250 calories and dinner should
be the smallest of your 3 major meals.
- Sleep 7-8 hours each night. This is way more important that people
realize and will be addressed in subsequent posts.
- Exercise regularly. I highly recommend 3-4 moderate to intense
workouts that integrate strength training and interval based cardiovascular
training each week with 1-2 active recovery days sprinkled in. Keep in mind, an intense workout may only be
30-40 minutes, but if well structured and done at a high pace you will get a
lot of bang for your metabolic buck. Active
recovery days can be hiking, biking, recreational sports, yard work, etc. If most of your workouts are done in an
indoor gym it's nice to get outdoors for your active recovery days.

Continued from the
When I was younger I
was never injured, now that I am older I have nagging injuries all the time.
As we get older our tissue quality changes, it loses water
content and does not bounce back from trauma like it did when we were
younger. The daily demands of our lives
forces us into repetitive movement patterns that create muscle imbalances and
restrict joint mobility, making us more susceptible to chronic injuries.
What to do about it…
- Corrective exercise. Seek advice from your
health professional about what corrective exercises make the most sense for
your particular lifestyle (i.e. sedentary desk job, plumber, etc.) Then ask
your health professional to design a 10 minute corrective exercise program you
can do every day.
- Sleep 7-8 hours each night with relatively consistent
bed and wake up times. This recommendation will be repeated over and over
because of its importance for overall health.
- Don't go 0-60 as fast as your car does. In all my years in the gym I have seen way
too many people (guys) “warm-up” with a set of bench press or heavy squats. The
first 10-15 minutes of your workout should be preparing your body for higher
intensity movement. In fact, your
warm-up is the perfect time to do your corrective exercise program.
- Supplement with a high quality fish oil. The positive health effects of fish oil have
been well documented in numerous studies in recent years. One of the most notable benefits of fish oil
is as an anti-inflammatory, and low inflammation is important for joint and
