You hit on some common misconceptions, but you also hit on some truths. For instance, you compare the human body to inanimate objects with respect to damage, but you also accurately point out that Obviously, living organisms are not the same as inanimate objects So, what's the difference? The repair process Man-made objects tend to wear out faster with ...

Although swimming alone in the middle of Lake Michigan sounds wonderful and has its benefits to you, swimming alone has life altering/ending risks. The chances may be minimal that something dangerous could happen, but see my story below for an example that bad things can happen. If something did happen you don't seem to have left yourself any communication ...

I've asked this implicitly of two qualified personal trainers. (One of the two usually trains Olympic athletes, so I trust his judgement.) Each time I said that I was interested in weight training to balance out the extra workout that my quads get (not just in the lower body, but to bring up my upper body strength too). Both of them said it was a reasonable ...

I've done a lot of offshore sailing and sometimes you'll get totally becalmed. Hot muggy conditions and the water is so flat you can literally shave in the reflection. It's hard not to jump in with conditions like that. Soap up, jump in, swim around the boat a few times, etc. A very famous and accomplished sailor named Bernard Moitessier would (solo) have ...

The answer to "what should a beginner do to physically prepare for X activity" doesn't change very much whether you're training for chainsaw-wielding, tennis, or martial arts: first get strong while doing your chosen activity, then add power and slightly sport-specific tasks, and add conditioning if your sport doesn't do enough to tire you out. If you're ...

No, explosive movements do not necessarily lead to injury. Performed correctly after a period of acclimatization, explosive movements are quite safe. The recommendation to be slow, deliberate, and under control at all times is meant for the general population. Most people are weak, prone to injury, and unlikely to seek capable instruction in explosive ...

5km or 7km mileage once a week is nowhere close to proper preparation for a marathon. You greatly increase risk of injury by running a marathon unprepared. Go see a doctor about your knee pain from the 20km race and forget about a marathon anytime soon. Many marathon plans have a long run of over 20km once a week for several months (and often with a run or ...

In my opinion, the dumbbell bent over row is a superior exercise for the following reasons: Your body is better supported--making this more desirable if you have chronic back problems It builds your grip much better than the barbell variation It keeps the shoulders, elbows, etc. in a more natural position. Now, in order to perform the dumbbell row without ...

I think what's missing in the discussion area is a bit more context. Taking all sets to failure would include the barbell sets. Taking your barbell sets to failure is not part of starting strength. Why take body weight exercises to failure? Body weight exercises don't cause near the stress on your body as the barbell work. Essentially, you can recover ...

Until elevators and steel girder construction around the turn of the 19th century, the tallest buildings were usually five stories. People worked in those fifth stories for years. Also, plenty of jobs have people walking up and down hills all day for decades, starting as small children. It's actually sort of sad that people consider eight flights of steps ...

I'm assuming the chafing is where your thighs are rubbing. Longer shorts, long underwear and bodyglide will help cut the chafing.

As a preface, although your concerns about the validity of the field of chiropractic are entirely warranted, it appears that Dr. Stuart M. McGill is indeed qualified. He was a former professor at the University of Waterloo, holding Ph.D., Masters, and Bachelors degrees in Kinesiology (Biomechanics), Kinanthropology (Biomechanics), and Physical and Health ...

If you were to decide to attempt a marathon given the training level you've described, there's an interesting academic article that may be helpful in estimating your likelihood of finishing without injury. The paper is by Yeung, Yeung, and Wong, "Marathon finishers and non-finishers characteristics: A preamble to success," Journal of Sports Medicine and ...

No, it should not be avoided. Like any machine, it's a tool, and it has a purpose. The article seems to refer to the fact that during a seated leg press, the weight presses down on your feet, and cascades through your legs and into your lower back, which is pressed against the seat. They neglect to mention that all weightlifting exercises has this problem, ...

This is an interesting question that had me thinking for a while. It's difficult to answer "why" exactly, other than saying "it is that way", so I'll try to describe the need for exercise and a few benefits it gives. @Alec's answer has neatly addressed your questions about wear and tear so I won't address those. One of the things humans ...

Neuromuscular Activation and Dynamic Stretching Here is an excellent video on a dynamic stretching routine for running. It demonstrates 9 dynamic stretches. I've been using this routine several times a week for months now. It is a great way to get warmed up before hitting the road/treadmill/trails. It includes: Walking Deadlifts (Drinking Bird) Knee ...

I hope that your knee issues have gotten better. However, there are a few things that can cause knee pains on a bike. Seat height - Having a seat that is way too high or low can place odd stresses on the knees, and if it is too high, can also cause hip issues because you have to "rock" back and forth on the seat to stay on the pedals. A good bike fit can ...

It doesn't sound bad. I recommend going above five reps for at least some sets, since I find the upper body responds well to higher volume and it's not the worst thing in the world to train some endurance. I expect you'll actually see better strength results that way anyway. The more common method of loading pull-ups is to use a dip belt, but the backpack ...

It depends what you mean by okay. If you mean "is it safe?" then the answer is simple: No, it is not safe. If you get into trouble you stand a high risk of death. No-one will be able to rescue you. But for the broader question of whether that means it's not okay, we can't answer that. It's up to you to assess the danger by assessing the chances of an ...

It is smart to look at fitness when you are young with an eye on preventing problems as you age. Back pain can have multiple causes. Some of the causes stem from degenerative changes of the joints, restrictions in the soft tissues (muscle and fascia), protective muscle spasms, disc degeneration and/or prolapse, and osteoporosis (weakening or thinning of ...

The bottom line is you want your shoulder in a neutral position. That doesn't necessarily mean full scapular retraction, but it's a cue that helps a lot of people. Considering your level of experience, and the fact you came off of injury I would advise you to use that scapular retraction, but only to the point where your shoulder is in a neutral position. ...

Most of the migranes are hereditary. Biological states may cause increases in free fatty acids and blood lipids, increased platelet aggregation, decreased serotonin levels and increased prostaglandin levels, which can cause the vasodilatation that precedes migraine headache. One possible reason for this is that a part of the physical reaction may be the ...

I've never had this problem, but I definitely recognize that it IS a problem. I think the best solution is for you to ask someone who is clearly more experienced. It might seem shallow of me to say, but I find it's very easy to figure out who is who in that regard. If you DO end up having to ask someone who might be inexperienced, I think you do in fact ...

Not only is it OK, it's something you SHOULD do. Pull your shoulders down and back. It pushes your chest out, and engages your lats, which is the entire point of the exercise.

The amount of (appropriate intensity) training volume necessary to maintain Ab Hypertrophy is typically going to be zero sets per week. The minimum volume required to make progress is also typically going to be zero sets per week assuming that you are also doing heavy lifts that require core stabilization like squats and deadlifts. If you aren’t however, (...

The basic answer is that although there has been quite a bit of medical research on this kind of thing, research does not strongly support any specific advice for avoiding injury as a runner. People used to say that it was important to use good running shoes that provided a lot of cushioning against impacts, and to replace the shoes frequently because they ...

According to a recent study, stretching of any kind before running does not aid in the prevention of injury. The study found that stretching before running neither prevents nor causes injury. In fact, the most significant risk factors for injury included the following: history of chronic injury or injury in the past four months; higher body ...
