We live in an age where everything that can be automated has either already undergone automation or is semiautomatic. Some things that had no business being automated are also automatic. We walk less, we run even lesser, our diets are a mess, and nearly everyone is overweight. Two generations ago people ate more non-organic foods, smoked and drank more and yet they were far healthier than most of us.
According to some studies that were conducted recently, it was found that 60% of Americans are not doing the minimum daily exercise needed. Furthermore, the study discovered that out of this population, over 25% were such that their physical movements were almost negligible.
However, since our lifestyles have grown to be such that our paychecks come from sitting in an office chair all day, most people need some sort of alternative that does not ask them to spend 9 hours a week in the gym.

This is the reason for the recent popularity of Pilates exercises. These exercises are simple so that anyone, in any physical condition, and of any age can perform them without the need of fancy equipment or lots of spare time.
Just as you would wear different apparel when going to weight training or an aerobics class, you should also pay attention to what you wear during Pilates exercises.
Make sure that whatever you wear is comfortable even if it is not fashionable. Pilates exercises can ask you to twist and contort your body into some awkward positions initially and the last you want is to be discomfited by your clothes.
Wear clothes that hug your body. As with all exercises, the clothes you wear during a pilates workout should permit easy breathing and movement and should not be susceptible to flapping around. Also make certain that the clothes do not weigh too much. Some track pants material can be downright heavy. The lighter your Pilates exercise costume the better it will be for you.
Pilates involves a lot of stretching and bending. At times like these and during certain postures, the obvious clothing items like extra buttons, zippers, beads can become a pain when they intrude between folding muscle layers so avoid those and wear plain clothing.
