I have to workout most days from 5-7pm (not necessarily 2 hours worth, usually 60-90 minutes). That's the only time slot available. I'm not an insomniac but I've had trouble the last couple months getting quality sleep that seems to be partly a result of working out in the evenings. I'm going to be making other changes such as avoiding heavy meals before bed. But I figured it would be worth asking if there were any exercises you have done in the evenings that help, and not hurt, a good night sleep. My current program is about 90 minutes of hypertrophy training upper/lower (sets of 8-14) and definitely taking many sets to failure. So, I'm pretty wore out after a workout and hungry....so I have to fight the temptation to eat ALL the food when I get home.
