In a minute, right after finishing this post, I am head to the gym to work delts, traps and abs. This is my longest workout each week. I will try to be done in an hour. That's timed from the moment I step on the gym floor to when I head back to the locker room at the end of my workout. Rest time between sets is around 1 minute. These are comparatively small muscle groups so no need to rest much between sets like I might doing leg presses or squats.
