Starting a new exercise program is easy when compared to maintaining an exercise routine for the long run. That is so true; we do it every year. When the holiday season ends and a new year begins, many of us decide that it is time for a change. We make big plans and get all excited about them. And it works really well for the first few weeks. We push ourselves hard and never miss a training session. We tend to think that if some exercise is good, then more is better. But unfortunately, this leads to overtraining, fatigue, and sometimes injuries. Exercising is not fun anymore and it becomes a burden. We lose the interest in healthy activities, and nothing seems to motivate us anymore. We start using anything as an excuse to skip workouts, and when we least expect, we are back to our old not-so-healthy lifestyle. Why does this happen?
