I'm a casual yoga-er, but when I meet people who are serious about yoga, they're always talking about their "practice." Basically, if you're really into it, you don't need to wait for a convenient class or a new episode from your favourite YouTube yoga channel. You work on what you want, where you want, on your own terms. If you're joining our December yoga challenge, now might be a good time to build your own home practice.

We’ve been through a lot in our October fitness challenge. We committed to doing some deadlifts, we psyched up and stretched out, we experimented with single-leg moves and unusual objects, and we learned how to get plates on and off the bar without a struggle.

Now it’s time to settle up: What did you accomplish, learn or otherwise experience this month?

If you’ve been struggling with our deadlift challenge because you don’t have easy access to a gym with barbells and heavy weights, this one’s especially for you. All of us can benefit, though. It’s time to try single-leg deadlifts.

Hope everyone's enjoying the deadlift challenge! Even if you're an old hand with free weights, deadlifts can be tricky to set up because the bar is on the ground, not on a rack, and you'll soon be dealing with weights that are heavy enough to be unwieldy.

We're deadlifting this month, and I'd love to hear how it's going for everyone so far. (I did one workout already, and will try to get in two next week.) But if you're new to this, or if you find the move intimidating, we have some suggestions for how to prepare.

Welcome back, friends! We’ve done a lot of bodyweight exercises in our fitness challenges, and last month we got out on the road for some running or walking. This month we head into the gym for some heavy lifting — but don’t worry, even if you don’t have a gym membership we’ll have options for you too.

It’s time to run (or walk, or otherwise locomote under your own power) one whole kilometre. Then take a break. And if you still have it in you, do it again. That’s right, we’re doing kilometre repeats this week in the Lifehacker Fitness Challenge.

When I was a kid, I knew kids who could walk on their hands. I figured it was the kind of thing almost anybody can do if they bother to try to learn, like cartwheels or riding a bike. I couldn’t, but, well, I just didn’t want to. I’d practise someday and then I’d be a master of walking on my hands.

We’ve talked about handstands in our upside-down challenge, and attempted to balance on our heads yoga-style as well. Today’s focus is less about balance and more about how getting sort of upside-down can help you work on strength.

iOS, Android: I’m pretty sure Alarmy is evil, but perfect, because a good alarm clock should be two-parts irritating, one-part useful. You don’t want to hate your alarm clock whenever it wakes you up each morning, but a great alarm app shouldn’t be very easy to turn off (tempting you to you go back to bed).

I cannot do a handstand. Or a headstand. I get kind of terrified even just trying to put my legs up above me onto a wall. Are you with me? Let’s get out of our comfort zones. If you can already do handstands, well, I’ll have some extra challenges for you too.

Get ready for strong legs and a poppin' butt, because July's fitness challenge is squats! This is the classic lower body exercise for a reason: Squats build pretty much every muscle below the waist, and there are a ton of variations for all fitness levels.

Hey friends, how's the burpee challenge going? Today I've got some modifications that will be perfect if the burpees haven't been agreeing with you, or if you're doing fine but you'd like to rope in a friend who has some doubts.

A month is a short time. Even by the end of our flexibility challenge, you may not find that you've made a ton of progress. But every little bit helps, and it's inspiring to see the progress of people who have been working on their stretching for years.

Our past two challenges were all about getting stronger, but this month we're going to do something a little different. We're getting stretchy.

Can you believe it's only a week until we complete our fitness challenge? Don't panic -- we have a great way for you to test your mettle for the final day, and it's part of a simple, doable workout.

Sick of running yet? We hope you're not, but either way, here's a new challenge for you. We're going to do a mini strength workout that is not tied to running. You can even work out indoors if you feel like it.

How's the Lifehacker Fitness Challenge treating you? If you're logging a ton of kilometres, great -- but if you've slacked off a bit or are just joining us, that's fine too. This week's workout is for everyone. We're going to run some tiny solo races, and they will make you faster.

You've set your goal and hopefully gone for a few runs by now. (If not, it's never too late - look out for our guiding on starting later today!) Now it's time to take a closer look at how you run. Fix your form now, and you'll be able to run smoother and faster in the future. We'll start with something simple: Count how many steps you take per minute.
