There are some good crossfit-type circuits out there, with something like Row, squat, pushup, crunch, repeat in different amounts. Those'll beat hell out of you, not something to do every day. If you're looking for conditioning, make sure you integrate other exercises, particularly running. Rowers, kind of famously, can't run at all, so make sure you don't end up like us.

Lyrics:

I've caught a lot of different fish. I know the cool places.

Where there's a sea of girl's smiles. No effort's needed to catch something there.

But only you, are the fish of my dreams! Only you are the fish of my dreams!

But only you, are the fish of my dreams! Only you are the fish of my dreams!

After a bite then I can catch around fifty over night.

From Leningradka and to Kapotnya There are flocks of Tanyas and Katyas of all sorts.

But only you, are the fish of my dreams! Only you are the fish of my dreams!

But only you, are the fish of my dreams! Only you are the fish of my dreams!

I've fished a lot, I've fished quite often. I even caught piranhas.

And once a true crocodile with huge jaws was caught.

But only you, are the fish of my dreams! Only you are the fish of my dreams!

It almost seems as if there are too many fish in the sea... I don't speak Russian, so I don't know if that idiom exists there.

Yeah, I've been using a Midori Traveler passport size as a wallet/calendar/commonplace book for a while now. It's really helpful to have a place to keep track of everything that's going on, both in my head and in my life.
