Yeah, ibobland08 posted the following in another thread:"The optimal time to train is as late possible while still having enough time to backload. For the average person who wakes up at 7 am and goes to bed at 11 pm, it is going to be at around 5pm. Basically you want to end your workout about 5 hours before your bed time."
This is what I've found to work best for me as well, that way I get ample time to backload, and have my food digest early in my sleep for optimal GH production.
