I would add some lateral raises and pushdowns to one of the days, and some rear delt and biceps work to the other. So you’re workouts are looking something like
Lateral Raises/Pushdowns (I’d do this as a superset)
Whatever abs work you want
Rear Delt Flye/Curls
Abs stuff again
And you could just train every other day alternating between the two workouts.
I also hate 5x5 rep schemes but that’s entirely up to you.
