Now that we're almost two weeks into our plank challenge, you've probably figured out that some kinds of planks feel harder than others. Tiny changes in your body's position can make a big difference.

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.

Practising yoga offers many benefits to your health and general wellbeing - but who has time to join a class? Between work, family and social engagements, there's simply no room for stretchy exercises down the park. Fortunately, it's possible to pack the mental benefits of yoga into just 10 minutes - without leaving your home or office. Read on for step-by-step instructions.

Dear Lifehacker, I've never been very flexible. I can't touch my toes and most yoga poses are a struggle. What are the least stretches needed, and most effective, to improve flexibility throughout my whole body?

Whether or not you're familiar with yoga, the idea of doing yoga in the air can seem ... odd. But not to worry: "Aerial yoga" doesn't mean you're going to be doing downward dog on a trapeze. Instead, you'll be supported by a soft hammock, which allows your body to let gravity do some of the work.

If you've never done yoga, it looks intimidating. People are flexible, fit, trendily dressed -- wait, I might be thinking of gym ads rather than actual yoga classes. It turns out you can have a great experience at a yoga class even when you're brand new and we asked yoga instructors how.

Infertility is rough enough without headlines implying your yoga practice is to blame. A recent study found that certain flame-retardant chemicals may make it harder for you to have a baby, but despite the downward-dog stock photos, yoga mats weren't involved in the research.

You don't have to be flexible to do yoga, although it certainly helps for some poses. But there are plenty of moves you can do even if you have the world's tightest hamstrings.

There are many ways to manage and reduce daily stress. Unfortunately, most of them require a significant time commitment. If you're already overworked and struggling to keep on top of things, all that "wasted" time will leave you feeling more haggard than before.

Our world moves at a breakneck pace, making it easy to feel overwhelmed and stressed out. That's why it's important to find time to take care of yourself -- even if you only have a few minutes here and there. Thankfully, Aura's meditation teachers and therapists had our busy schedules in mind when making Aura Premium, a science-backed mindfulness tool to help you give anxiety the boot.

If you have back pain, yoga may be the last thing you feel like doing. But after 12 weeks of a gentle, beginner-level yoga program, people in a recent study had as much pain relief as those who did physical therapy sessions. And either type of exercise worked better than doing nothing at all.

Yoga can be more than a relaxing way to spend a rest day. It can be a challenge in itself: you can build serious strength working up to impressive poses like Crow or Dancer.

It sucks when office anxiety spills over into time you want to spend relaxing. In an attempt to combat post-work stress, I tried this quick yoga routine designed specifically to help you de-stress and it actually helped me feel super refreshed after a long day.

Yoga is great for flexibility, strength and balance, but we've never taken it seriously as a form of cardio. According to a new study, though, cycling through poses at a fast pace -- we'll show you how -- can give you a workout on par with a light aerobics class.

If mornings aren't your thing or you're prone to an afternoon lull, try this quick yoga routine aimed at boosting your energy. You don't need any equipment and you can do this exercise even if you don't have much room to move.
