lower arms died

Bleh, no luck with the straight bar grip on the cable row... my lower arms quickly died, even later on the front pull down.
Squats went decent. However, it's pretty clear the extended fasting and the calorie deficit over a week is making gains in muscle mass very difficult. And this seems to be the case even though I'm giving myself two feeding days after training.
Perhaps I need to try with even more feeding days, but for the moment I really want to get my body fat even lower. I do think the extended fasting has had effect on the body fat percentage, so I'll keep it up for a while longer.
But I'm really starting to look forward to eating a lot and hopefully seeing the gains start happening again!

I'm using EAA and creatine nitrate supplements, and also some omega 3.

Could be stricter with the diet though. It might be the case that I'm eating to much carbs on training day, and not enough protein.
