I started as soon as I bought it! Sad to say, I was out of breath. Im looking forward to doing more. Im hoping this will kick start me to do other more active things. I love the activity tracker too! I believe it will motivate and challenge me to do more. You can earn or buy more exercise packages. Im going to try to earn them so it motivates me to workout more. If I get bored, I also have another workout app I can combine. Id be curious to know if anyone has lost a significant amount of weight or inches from this app?
