Walking and results from today

Well, I tried Insanity and all that I can say is this: it is hard.  I could not keep up nor did I last 10 minutes. Maybe I should try Insanity later.  I went walking today.  I walked for over 1400 steps, 2.4 mph, and burned 67 calories in just 15 minutes.  Now if only I could actually lose weight.  I gained four pounds despite exercise.  Losing weight is not that easy, but judging from the results from today, the exercise is well worth it.
