Help with my work out plan

baileyione

So my friend took me to a weekly PT that future marines do, since I showed interest into maybe going into the military. I learned that I was pretty out of shape!
I need advice on a good workout regimen with maybe some weights and how to build my endurance for running up! I can do spin classes no problem, but I can't run to save my life! I also have practically no upper body strength!
I'm not looking into a crazy weight loss plan, I'm not terribly overweight, I mainly want to build muscle and increase my endurance. I wouldn't mind losing fat along the way though :P
FYI: I do work at a HUGE gym! So I have access to a ton of equipment.
Thanks

i find that when i want to increase endurance, circuit training is the best, the oxygen deprivation after each set improves cardio endurance, usually i'll youtube an exercise and start from there. here is an example
