And sleep! I am focusing on sleeping more this year. It does wonders for my productivity.

Yes! Naps help me greatly and since I work from home, I consider them a luxury.

Important point: it doesn't have to be vigorous, nor a big production.

A daily 5 minute half-brisk walk gives a disproportionate share of the benefits.

I recently started running, it's awesome!

I agree. I've been a regular runner for a few years now and its a great way to relax, let off some steam, and get into great shape. Also depending on where you live there's usually a tight-nit community of runners so you can make some great friends.

I've recently moved from running only to running and lifting weights at the local gym — the gym is even a short run from home.

It's been a great way to meet new people too.

I agree, although the way you make your argument makes you sound like a fanboi.

The advantage of cycling is that you get tired/bored when you are 30 miles away from your house. When I run, I get bored after a block, and can just walk home :)

I have two bikes. But I still prefer running everyday, keeping cycling more of a holiday activity.

"I believe that Running is rubbish, slow and boring, and you never get anywhere exciting". FTFY.

Have you ever run in a natural park or a mountain?

Same here. Helps keep my mind and my mood healthier and I can get more done.
