I keep seeing posts from folk 2, 3 or 4 weeks in to the program that are all upset because they haven't lost weight. Well, they shouldn't be. For a couple of good reasons it's entirely possible to gain weight when you begin exercising…
For a start you’re likely to be hungrier, all this leaping about brings on an appetite, so you’re probably inclined to want to eat more, not less.
Your muscles, not having been used to said leaping about, are growing. They do this in an effort to ensure you can leap about in a similar fashion next time. Only next time you ask them to leap about even more, so they get even bigger. So the cycle continues… Bigger muscles mean more weight, they’re quite heavy things muscles. And, they need food (protein mostly) to do all this getting bigger.
Honestly, don’t worry about it. In all likelihood you’re losing fat and gaining muscle, exactly what you want to be happening. Even if you’re not losing fat, you’re still heading in right direction.
Get to week 9, 10 or even 11. Once you’re comfortable running half an hour 3 times a week regularly then it’s time to start setting weight goals. And that’s another story…
