BEST OF ALL, AS I SAID BEFORE, THIS IS ALL.........FREE

You don't have to spend 30 bucks a month on a gym membership. That's fine, if that works for you, and you can afford it. A lot of people can't, particularly in light of the current state of the economy. Go to the gym and work out with a medicine ball?.................naw, not really necessary. Ogg had lots of equivalents, and it didn't cost him a cent (not that he would have known a "cent" if he saw one! Get out and just DO STUFF! A great example in the picture here is a really simple example of "nature's medicine ball."
A rock or a log will do, as well. You don't need to run or walk on a treadmill, although I like to do this, too. You can walk on the street, in the mall, you name it. You just gotta keep moving, and moving in different ways! Mix it up a little. Don't get into a rut of doing the same thing over and over again. Your Paleolithic body is really smart and efficient. If you do the same thing over time, it will learn to do it more efficiently, and use less energy to do the same task. If you keep surprising the body, it will keep getting stronger and more efficient in multiple ways. This is how you will achieve REAL Primitive Fitness! Assuming your health it good, you can do all sorts of things to get more fit. When is the last time you climbed a tree? Probably when you were 8. How about the last time you actually did a somersault? Think about it. Kids are really flexible, and full of energy. If you still are fortunate enough to be young, don't lose those qualities! If you aren't, find a way to recover some. Stretch those old muscles, tendons, and joints a bit. Just a little at a time. Don't overdo it. There's no rush. Just......................MOVE!
