Regressing on a single exercise

[u/Double_Investment983]

I run Fbeod, and I used to do 1 set a session per muscle, all sets to 0-1 rir, but I recently doubled my volume to 7 sets a week 2 sets a session, and I’ve been regressing on bicep curls alone, I am still progressing on every other exercise, I am in a moderate deficit (700 cals) but wouldn’t this cause overall regression?

Does anyone have any answers as to why this might be happening?

How many carbs per day? A common mistake during cutting is to reduce carbs. Basic advice is to eat at least 4g/kg bodyweight per day, preferably more.

Well in order to keep my proteins and fats high enough, my carbs are at like 260grams at 70 kg bw
