Get your Flight physical done by an Army doctor. I went to an air force base initially. Though it was all good..then had to do the entire thing over again. Have your recruiter set you up with the army side of things...because the army knows what the army wants.
Even if you get the physical printed out so you can hand carry it to a Navy, Air Force, Marine, or Coast Guard base, tell your recruiter you want to have it done by the Army. It will save you a headache and time.
Also, if your over-weight look up the standards, and achieve your "ideal weight" or your "ideal body-fat" before you take the physical. you want to be approved not denied.
hope this helps.
