OP Get back In shape first then think about the girls.

Believe me, your one of the masses,,, you made no lasting Impression on anyone you wobbled In front of.

Start some deep knee bends, squats and get some of those ankle weights.
Find a curb,,get your toes on the curb and hang your heels off,,,Calf push-ups feel so good

As for the gut,,your goal is the Grand a week club,,thats 1,000 sit-ups weekly..
spread em out for less pain. morning and evening,,start at 10 twice a day,,,70 2 times daily will come.

If your a geezer or a geezer In training like me,
get a wrist worn heart rate monitor, so you can make target zone consistantly.
