John, who is training with margaret, has no heart monitor, and he cannot afford to buy one. he has to rely on his watch and his ability to measure his own pulse on his wrist. john is 27 years old and wants to train at the higher end of aerobic range, between 75% and 85% of his maximal heart rate. on his last run, john counted 30 heart beats in 15 seconds. is he training within his target range?

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.
