For example, I start off my day with 3 sets of max-rep pushups immediately after waking up. This gets my blood circulating and removes any lingering drowsiness.
I also take a daily fish oil supplement for the myriad benefits (Google it, if you have to).
What do you do?
The three fundamental things you need to do is: eat well, exercise and sleep enough. Sleep 8 hours (yes, this varies from person to person) every night. Eat well, and get educated on nutrition. Don't believe the labels+marketing - just keep it fresh and simple. Exercise every day - it doesn't have to be anything intense...a 45 minute walk or a casual bike ride is fine.
The +2 are the two things you can do to have enough time to do the three above: don't watch tv, kill the long commute.
