Plus when you wake up and work out first thing if you're naturally lazy and slothful like I am you can't make up an excuse later in the day to get out of it because you already did it on autopilot first thing while you were still half asleep and just waking up!

10 years ago I could get up at 6am, have a workout and get back by 7:30 ready to start the day.

These days I feel so groggy in the morning that there's just no chance. After 3 cups of coffee I might feel sort of okay and awake by 11am.

Sleep problems?

Some problems falling asleep, once I fall asleep it's uninterrupted and I wake up around the same time without an alarm.
