Regarding your sleep time of 6-6.5 hours and how it affects muscle growth…
It really depends on whether that is enough sleep for you. Do you feel well rested?
If you are not well rested that can have a huge impact on your ability to gain muscle and lose fat. Why? Well, because how soundly and how long you sleep determines:
- How much Test is produced
- How much GH is released
- To what extent Cortisol levels are mopped up
Obviously those three things are going to have a dramatic effect on your ability to build muscle as well as a bunch of other things related to your ability to exercise and/or perform.
One of my friends just read over 60 studies on sleep – its impact on muscle, fat, and athletic performance and submitted two very in depth articles on the subject right here to T-mag.
I don’t want to steal his thunder, hopefully they’ll appear soon
