+1 Start with a little. If you don't, it will never become a lot. Over time, you'll realize that you can jump rope for three minutes, then four or five. You realize that you can walk at a brisk for a half a mile, then a mile, then a couple of miles. Then you can do a more strenuous hike, or start jogging. You can't go zero to sixty overnight, but each little bit builds a little bit of strength or endurance or speed, and it adds up. |
I would say it is not waste of time, even a little.
For better impact - do it right after every meal, even if it's just short walk around the house. There are studies that even light short exercise right after a meal have positive impact on insulin sensitivity, and in turn, on blood sugar levels (and mood to some degree). |
