Do squats and get plenty of sleep.
Good!!
I'd like to add: higher-end reps for squats as well as other big, multi-joint compound exercises to produce lactic acid buildup in the blood. This is the heart of the very effective lactic acid training methodology.
German research has learned that the lactic acid pathway is more effective than the aerobic pathway for fat-burning because of the hGh response.
As for sleep, I've mentioned on here several times the benefits of sleep on hGH levels, as well as supplements and other practices to improve sleep architecture.
If anyone is interested, search the Nutrition board with keywords like circadian rhythmicity, delta wave sleep, melatonin, GABA, and Montague.
