Then I recommend cross country jogging.
And I do mean cross country - multi-terrain (asphalt, grass, dirt, etc.) and multi-leveled (hills, obstacles, steep, shallow, jumps, etc).
As for cutting, that is, if I had to pick a number, 75% diet. Abs are made in the kitchen. If you want to get cut, you're going to have to do long term, low intensity cardio (30-60 mins), and watch your caloric intake rigorously. Aim to consume roughly 300 fewer calories daily than you burn. Your goal should be to shed roughly 1-2 pounds of fatty mass per week. At a rate faster than this, your body is likely to slow its metabolism a bit, and you may begin to lose lean mass and water weight, giving you a deflated, flat appearance.
Above all, remember you are looking to change your BODY FAT PERCENTAGE, NOT YOUR WEIGHT. They are completely different measures.
