initial issue is that I have some excess fat most obvious under chin and around . aim is maybe not so much to lose weight but certainly to shift the fat, so muscle gain is fine with me (just not crucial).
I understand the most common method is to measure calorie intake, compare to calorie burn and track weight changes. Now this is where it gets confusing... job for most of the year (3 out of the last 5 months so far) involves very intense excercise such as lifting and aligning large metal brackets weighing between 70 and 110Kg, then swinging a 5Kg hammer at them for 20-30 minutes (repeated every 1-2 hours), a lot of lifting, walking, running, carrying, climbing over stuff, dragging machinery about. A typical day is 12-16 hours, 6 days a week. The last trip was 2 months in Tasmania so there was a lot of sweating! Now, some times I don't have such an active day as normal, so if I feel this is the case I do a pile of press ups and sit ups in hotel room. As you can imagine after a 16 hour day theres not a lot of time left after eating and sleeping. diet when Im away can be difficult to control as we are provided with meals and packed lunch but it is usually very good food (lean meats, fish, fruits and vegies, whole grain bread etc). I try to spread packed lunch out in to a few snacks through the day, but breakfast and dinner are set to when we are at the hotel.
When Im at home I am as active as possible, mountain biking, trials bike riding, active work time etc. I also do M100 3-4 times a week.
So how do I count how many calories I burn in a normal days work? Is it accurate enough to add up a load of 'similar' exercise routines until it equates to 12 hours?
Also, how come I am still holding excess fat?
I feel I have gone on long enough but if you need more detail on diet etc I can provide this.
Any suggestions or advice from any one welcomed

Thanks
Dan
