Insulin Sensitivity - What's happening?

Hi guys

So at the start of the year I began weight training at the gym and over time my insulin sensitivity increased. In addition I was playing a lot of football and squash so it was good! My diabetes was well controlled and I felt good! My bolus insulin was around:

breakfast - 10 units novorapid
lunch - 10 units novorapid
dinner - depending on food I'd typically take 12-15 units

Levemir doses: 2 doses of 23 units at 12 hours apart (midday and midnight approx)

Here's the thing I really don't get

I've moved to Paris and for the last few months I haven't been weight training in the gym

For the first month this was ok but in the last few weeks (i'd say the last 2 weeks) my insulin resistance has shot up!

Now I'm taking almost double the novorapid in the mornings for breakfast

breakfast - 17-20 units novorapid
lunch - 17-20 units novorapid
dinner - 15-20

and then my levemir dosage has gone up by 10 units per day!

Levemir dose: 2 doses of 28 units at 12 hours apart

What could be behind this shoot up in insulin resistance??

Is it just simply the fact I've stopped doing anaerobic exercise? Are there ways I can increase my sensitivity again?

I'm worried because I don't get to go to the gym much as my hours are long and all I do is press ups and situps in my apartment!

I play football once a week but I don't feel that's enough! :/

any advice or tips would be really appreciated!

thanks guys

I'm getting into running now so I'll be going for a jog every other evening starting this week and we'll see the progress!

I'll most likely get some weights at my apartment and carry on doing the push ups (fast ones) to keep up the anaerobic exercise

@Juicyj Thanks juicy my work is pretty intense marketing and they don't allow any allowances

the gyms in paris cost 60 quid a month! I may just try it for a month, my diabetes is so much better controlled when Im lifting weights!
