Where should I add in my Tri exercises?

Hey guys

I've been hitting the gym again recently after a break with a niggling lower back injury and I've modified my old routine to take out some of the things that seemed to aggrevate it. I was doing Stronglifts before but now I'm doing:

Day 1:

Squats
Bench
Flys (cable)
Close grip bench

Day 2:

Deadlifts
Military Press
Pressups (to failure)
Wide Grip Pullups (to failure)

Where would you add in some tri workouts? I don't feel like they're getting hit enough.. would welcome any suggestions though, I know it's not a lot I'm just trying to ease myself in. My form on squats/deadlifts is perfect according to everyone that's seen so I don't have trouble there.
