Just wondering if it ever gets easier? I'm finding myself stuck on the last run of level 4 because on matter how much time I give myself in between - it's torture to finish. I can finish - but there's no way I can do level 5.
I'm wondering whether I have medical asthma as my breathing hurts and isn't easing at all and I'm not doing anything to hinder it in between runs.
It just doesn't feel like I'm getting fitter or enjoying it at all. It's really really hard work.
