Why do you train to failure? Very few training programs that I have seen encourage lifters to regularly train to failure. I think westside barbell's program may, but that is for people competing in powerlifting.
Also, it's my understanding that when most people talk about exercising for better sleep they are specifically talking about low intensity steady state cardio exercise.
