Its crazy but I feel like a penguin whenever I walk (now youâ€™re starting to imagine how penguins walk LOL). The culprit –Â sedentary lifestyle or lack of physical activity. I’m sitting most of the time and my legs bear the pressure when I walk.Â My family and friends always encourage me to take time to do some stretching for a few minutes everyday if I can’t afford twice or thrice-weekly exercise sessions. I know they mean well and I welcome their suggestion, but I can’t easily shake off this bad habit (lack of activity). I wish I could just buy electric muscle stimulator that I can put on my back, legs or my tummy area without leaving my computer. But will it make a good replacement for exercise? What do you think?
