If
you like to exercise, you may have read a lot of articles about the
latest scientific studies on the best workout routines. High-intensity
interval training is all the rage at the moment. There are also
seven-minute and 20-minute workouts that promise results in just a short
period of time.
But what is the best workout routine for you? Daniel Duane, a Men’s
Journal editor, recently wrote in The New York Times that there are in
fact no cutting-edge scientific studies on workout routines. Duane
talked to Martin Gibala, an exercise physiologist at McMaster University
in Ontario, Canada, who said there’s not a lot of research money out
there to fund applied studies. On matters as simple as how many sets and
reps best promote muscle growth, Gibala explained, “We can’t nail down
the answer.”
Physiologists do research, but they only study questions of basic
science, like the relationship between protein and muscle adaptation.
Simple principle
Of course, physiologists are not the problem. The problem, according to
Duane, is that everybody in the fitness industry uses basic science and
then twists the results to come up with something that sounds like a
scientific recommendation for whatever they’re selling.
Few personal trainers or gym coaches teach their clients to train
independently by showing them basic barbell lifts and telling them to
add weight each time. Instead, they invent confusing routines, so the
clients never leave them.
The truth about the best workout routine is simple, says Duane. The
human body is an adaptation machine. If you force it to do something a
little harder than it has done recently, it will respond — afterward,
while you rest — by changing enough to be able to do that new hard task
more competently next time. This is known as the progressive *overload
principle. All athletic training uses this principle through small,
steady increases in weight, speed, or distance.
So if you run, run an extra 50 meters or a bit faster the next time. If
you lift weight, add a half-kilo weight during the next workout. Always
push yourself to your limits and you will be surprised at how strong you
can become.
Yeah, I love your post! You do a good job.
