probably too short of rest periods.
I set up mine so that I do antagonists back-to-back, sometimes supersetting when I'm doing more than 1 set
for instance, here's 2/3 of my routine, how I perform it
squats x2
SLDL x1
Calf raise x1
(DB press x2
Cable rows x2) superset #1
(chest dips x2
weighted chins x1) superset #2
also I'll sort of informally alternate between different chest exercises
one day I'll do 2 sets of db flat press, and I'll do them before chest dips (which I do for 1 set)
the next day I'll do chest dips first for 2 sets, then later db press for 1
this way I feel each movement gets a chance to be done fresh. In the long run this probably doesn't affect everything but it provides some variety
