We've read - and written - enough stories about Victoria Beckham to know that readers online can be particularly harsh when commenting on another person's weight.
Typical comments included 'this woman needs a cheeseburger' and 'am not a fan of the skeleton look'.
However, what was refreshing was the number of Redditors sticking up for Luba, saying that these pictures inspired some of them to take up yoga, others described her as 'beautiful and not because she's naked' and one said: "I wish I had the physical strength to do half of that."
Take a look at the pictures which are hosted on Imgur:
Secret Yoga Club
Set in different venues around London, <a href="http://www.secretyogaclub.co.uk/" target="_blank">Secret Yoga Club</a> is a yoga class, intimate gig and delicious supper club all rolled into one. Not to mention it's seriously cool. Founder and yoga teacher Gabrielle Hales teaches yoga flow and Jivamukt to a class of no more than 18. At the end of the class during savasana (where yogis lay on their back in relaxation "dead body" pose) the class is treated to a private gig with an up-and-coming artist -- for us it was the dulcet tones of Luisa Gerstein from <a href="https://www.facebook.com/Landshapes" target="_blank">The Landshapes</a>. The table is then set and the class are treated to a delicious vegetarian meal -- ours was prepared talented chef and ice-cream maker <a href="https://twitter.com/antoninaparker" target="_blank">Nina Parker</a>. "One of the reasons that people aren't keen on yoga or exercising in the evening is that they feel like they are missing out on socialising or doing something with friends," Gabby told HuffPost UK Lifestyle. "I thought if I could bring everything together -- the yoga, beautiful live music, food and friends -- then it would be the perfect evening!" She's certainly on to something. But shh! it's a secret. Our class was held in the eccentric <a href="http://www.londontown.com/LondonInformation/Entertainment/DalstonBoysClub/eb47f/" target="_blank">Dalston Boys Club</a>, which -- filled with mannequins and lit by candlelight -- made for the perfect ethereal setting.

Inspired by aerial circus art and Vinyasa Yoga, the silk hammock is hung from the ceiling and used to suspend participants into seemingly impossible yoga postures. The class begins with simple poses like downward dog, lunge and warrior, but uses the soft trapeze as a prop for an even deeper stretch. Then it progresses into more challenging postures like hanging diamonds, handstands and the inverted yogi, to create a weightless alignment that strengthens muscles and releases pressure from compressed joints.

Housed in a pop-up inflatable heated studio -- think bouncy castle, but without the inflatable floor -- Hotpod Yoga aims to bring heated yoga classes to the masses. Classes are taught using the Vinyasa (or flow) yoga method, which uses controlled breathing and a range of challenging moves to strengthen, tone, detox, calm the mind while promoting weight-loss (one session promises to burn 700 calories). <a href="http://www.huffingtonpost.co.uk/2013/02/28/tried-and-tested-wellbeing-hot-pod-yoga_n_2780209.html" target="_blank">READ MORE</a>
Bikram -- a 90-minute class held in 40C conditions, during which yogis complete 26 postures and two breathing exercises -- has many benefits: fitness, flexibility, stress-relief, weight loss and improved posture. The heat increases the flexibility in the muscles and joints, allowing you to hold difficult postures for longer and push your body to the extreme. When HuffPost UK Lifestyle's Brogan Driscoll tried the 30-day Bikram Yoga challenge, she noticed a profound improvement in her balance, strength and cardio fitness from one class to the next. <a href="http://www.huffingtonpost.co.uk/2013/05/07/tried-and-tested-wellbeing-bikram-yoga-30-day-challenge_n_3230258.html" target="_blank">READ MORE</a>
<a href="http://www.unitedmind.co.uk/clubs.php">Laughter Yoga</a> combines unconditional laughter with yogic breathing (Pranayama). Anyone can laugh for no reason, without relying on humor, jokes or comedy. Laughter is simulated as a body exercise in a group; with eye contact and childlike playfulness, it soon turns into real and contagious laughter. The concept of Laughter Yoga is based on a scientific fact that the body cannot differentiate between fake and real laughter. One gets the same physiological and psychological benefits. <a href="http://www.unitedmind.co.uk/" target="_blank">FIND OUT MORE</a>
