Nobody makes a greater mistake than he who does nothing because he could only do a little. - Edmund Burke (1729-1797, British Political Writer, Statesman)
At some point in time, our society was convinced that exercise needed to be a complicated and lengthy undertaking. Unfortunately, this has paralyzed many people in their attempt to embark on an exercise program and for some, it has just given them another reason - or better stated - excuse, for not doing some form of physical fitness.
I once had a brief conversation with a doctor who was no longer working out because his schedule did not allow him to continue with his 5 days a week / 2 hour sessions. I posed the idea of doing some type of exercise 2 -3 times a week for 20 - 30 minutes. His response was "that's not enough time, I need more than that to get any benefits." To which I responded "A little of something beats a whole lot of nothing."
I recommend frequent, short duration workouts, not as a compromise to "real training", but as a productive approach to becoming stronger and healthier. In fact, an approach of 10 minutes a day doing some kind of physical activity can do wonders for anyone so if you think you don't have time to exercise or a little isn't worth the time, you are dead wrong. - Fred Fornicola
