Well, on Friday I did do chest/shoulders/tris. I was sorta trying to squeeze it into a half hour, so my rest time between sets was lower than usual.

This was my routine:

Dumbbell incline bench press 3 x 20lbx3DB x 8-8-6
Lateral dumbbell raises 3 x 10lbx2DB x 7-6-5
Arnold Press 3 x 15lbx2db x 5-6-6 (I can usually do more reps of this - about 8. Not sure why today was worse)
Rear Delt Machine 3 x 40-50-50 x 8
Seated Tricep Pressdown 3 x 80 x 8
One-arm Tricep Extension 3 x 7.5 x 8 - 8/7 - 7.5/5.5
Lying Tricep Extensions 3 x 25-15-15 x 2-12-12

I think I'm going to try doing free weights for rear delts instead of the machine. I hadn't done rear delts for a while and I want to start including them in my routine again.
Also, Built had recommended that I do lateral raises before Arnolds or Military presses, but I think I'm going to try doing them afterward instead. My arnolds have felt rather weak lately.

Yesterday I did 26 min on my home stair climber. It's a different kind of motion than the one at the gym, but it works in a pinch.
