To become a personal trainer, you only need to graduate from high school and be at least 18; as far as getting a high school diploma goes, there are no specific requirements for being enrolled into a public high school. Your only responsibility would be to pass your classes and achieve all the required class credits which varies from school district to district, After this you must become certified in CPR and AED usage, the former of which is typically done in high school. After this, you must then present a government issued photo ID, for example, a license. You do not need a college degree to become a personal trainer which makes personal training a relatively easy career to pursue.
