I'll join in this thread, and perhaps return to it. I've been working on getting fit over summer.
Running 1.2km frequently to raise my metabolism at 7:30am in the mornings, before work. My times are coming down fast.
Run 1: 7 min 59 s
Run 2: 6 min 57 s
Run 3: 6 min 56 s
Run 4: 6 min 53 s
Run 5: 6 min 43 s
When I get back from work (6pm) I'm doing ab work outs daily. Usually two sets until it feels I am being knifed, and subsequently in great pain.
Twice a week I then do weight work outs. Shoulders/ Biceps/ Triceps/ Chest/ Legs. One to raise metabolism higher, and secondly to gain muscle.
Diet isn't great, but it's fine. Milk and oats for breakfast, wholemeal sandwiches +fruit for lunch and dinner that varies daily. No fizzy drink, no sweets, no alcohol.
Seem to be doing ok so far. It's quite a manageable plan, nothing that requires too much effort.
EDIT: 66kg around 5 ft 7. Rough calculations of 13% body fat.
