You know a great way to get a good workout in a short period of time is? Running. You should run for 25 minutes 3 to 4 times a week. There are three types of workouts you should do within this time. Long Slow Distance (LSD), Continuous High Intensity (CHI), and Interval (INT). For LSD, you run the entire time for a long distance slow enough such that you can talk comfortably the entire time. For CHI, you run 15 minutes at 90-95% of your maximum speed and then recover. For INT, you run for 2.5 minutes at maximum speed followed by 5 minutes of recovery, repeating until done. Congratulations, you're now more physically fit than most of the population in less time than the typical nerd spends caffeinating each week.
