The first way in which I would improve my activity level would be by walking everywhere, as opposed to driving. This would force me to exercise while gorcery shopping, going to school or running errands. I would measure this by using a pedometer. The other measure I would implement would be lifting weights at home before school. I would measure the effectiveness of this routine by tracking the weight I'm lifting, and whether this improves over time.
no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.
the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
