running/jogging for 30+ minutes is where you should start.
Then get some light weights (dumb bells), stand on one leg (I know it sounds ridiculous) and do 1 set of 20 (15 works too!) repetitions doing curls. Alternate Legs and repeat. Do 4 sets.
Then (once again while standing on one leg) do the same thing except do an over-head press (military press).
Working out on one leg will strengthen your core muscles, thus working your abs while you work your arms. This is something to get you started.
