There wasn't much time this evening so took it easy. The core routine is getting easier compared to a few months ago.
I'm not sure how much I trust the fat% on the scales. It seems to have a mind of its own. Maybe I need to wash my feet first? it works by passing a small electrical current so i'm sure dirty feet wouldn't help. Anyway i'd be happy to get down to single digits; 9.9% would strike a nice balance.
I now need to wait 2 days before going all out on the turbo - two weeks ago I thought doing this too close to the core session made it difficult.
