activity level conundrum

Hi folks,

I'm lost as to what i should set it to as i have a very odd set of circumstances which make it hard (at least for me) to work out at what level i should be.

I work every other day, and my job is relatively hard work. It starts off with about 30mins light activity, then an hour of demanding activity, then back to a few hours of light to medium activity. This working day is accompanied by me cycling to and from work approximately 3miles each way taking 15 mins a time. It is also accompanied by me hitting the gym after work for a couple of hours.

This is all well and good but the days i don't work, in between my working days, are very much sedentary. Apart from housework, prepping and cooking, and other assorted necessary mundane tasks, i spend the day parked on my backside.

So, should i set it as sedentary due to my days off, medium due to my working days, light as a middle ground. If i set it as anything other than sedentary, should i log anything under cardio or is it already logged due to me picking light/medium as my activity level.

Anyway, some guidance would be much appreciated as I'm finally getting back on the weights after losing a lot of blubber. I really don't want to minimise my gains by setting it too low or end up stacking weight back on setting it too high.
