Lifehacker Fitness Challenge

I tried some PNF stretching, aka PAILs and RAILs—and it works.

Stretching can even be relaxing, if you give it a chance.

In which I praise my flexibility routine, even though I don't know if it's working yet.

We're probably all a little more flexible than we think.

We learned how to build our butts, get more sleep, and fail gracefully—and maybe you can, too.

Chilling on an exercise bike while reading a book is the kind of thing we need more of in our lives.

I will never be mistaken for a professional skater, but my daughter thinks I am very good.

Mastering the fundamentals I never bothered to learn as a teenager.

I'm old enough to remember when inline skating was cool. And I've lived long enough to see it become (sorta) cool…

Just like with any sport, training and being "out in the field" are very different.

Or: How focusing on something other than "getting hotter" made me realize exercise works.

I am not good at sticking to a routine, but a looming hunting trip demanded it.

There are different styles of PFD (personal flotation device), and it's worth knowing the difference.

Yes, they work. They're even affordable these days. But they kinda require a $150 accessory.

You're not a kid anymore, but there's still plenty you can do.

An inflatable won't be the best boat, but it's definitely more than a toy.

What do I need to start kayaking? How do I paddle? Where's the best birdwatching?

Can virtual reality games count as exercise? Sure. Do they give you a good workout? Depends.

I'm still on the case: can you get a good workout in VR? Here are the best games I've tried.
