Exercise shouldn't be a chore, a hassle or even boring, but when it is, getting into a fitness routine is challenging. Adopting a regular exercise practice becomes easier when we consider and remember the benefits of why we are exercising. Several studies preformed on habit-forming activities reveal that there are many variables that determine the time "required" to turn exercise into habit. It is hard to say with certainty that it will take exactly 21 days of doing something consecutively for it to become a habit - your determination plays a large role. My suggestion is to commit to 30 days of exercise. If you can make it through the first month, it becomes much eaiser to sustain. Please read the rest of my most recent article "How To Begin a Regular Workout Routine" and determine how to make exercise a part of your daily routine.
