Jogging and crunches are both a waste of time, energy and are potentially destructive to your body. I'm not kidding..Stop doing these.

A few really simple changes you can make which will literally make night and day progress with little effort.

-Don't eat carbs in the morning
4 whole egg omelette (cooked in butter, with meat, tomatoes etc)

-Walk for an hour a day in a low insulin state
That means in the morning or before dinner after 4-5 hours of no food.

-Instead of jogging/sit ups do High intensity stuff
Lift weights, skip, sprint, circuits..anything where you are working hard for 30-90s, recover, repeat.

-Pushups are a good exercise but,
To get a strengthening/shaping effect you need to be progressive. I disagree with Kowalski with this. Stick with 3-5 sets, increase total volume over those sets over time. rest 2 mins between each set.

This is kind of what I do..Picking up girls..not so great. Exercise, sport, diet, physio..I know my stuff
