I am attempting to start a new career in a law enforcement type job. There is a required fitness test, and I have 16 days to prepare. I will need to do at least 25 pushups, 35 situps, and run 1.5 miles in 15:30. So far I can do about 15 pushups, 20 situps and I can run the 1.5 in about 18 minutes. I plan on interval training on my treadmill to decrease my running time, and I'm relatively confident I'll do fine there, but I need some help on what exercises (besides the obvious pushups and situps) I can do to increase my strength enough to pass my tests.
