Kim Kardashian usually works out in the comfort of her converted garage inside the Hidden Hills, California mansion she shares with husband Kanye West and their three kids North, Saint and Chicago.

But on Wednesday the 37-year-old reality TV star visited a Los Angeles beach for her sweat session.

The raven-haired pinup wore a grey outfit that consisted of a crop top and shorts as she did the tree pose and performed lunges while with two female friends. Later the Selfish author stripped off her shorts to wear only high-waisted briefs that gave a generous view of her backside.

Kim was not shy with her body as the back of her briefs fully exposed her backside.

But the Keeping Up With The Kardashians star has reason to be proud of her 5ft3in frame - she is in the best shape of her life thanks to workouts with trainer Melissa Alcantara.

Not only does the mother-of-three have a tiny waistline, but she also has sculpted arms, toned legs and abs.

The siren wore her long raven locks up in a top semi ponytail with the rest of her tendrils flowing down her back. Her glam was fully done to perfection suggesting she was doing a photo shoot, even though no cameras were spotted.

Kim has not often talked about doing yoga, usually preferring weight lifting and repetition workouts, but she seems to have taken a new interest in it.

The former DASH owner has credited her trainer Alcantara with getting her in top shape.

'Shout out to my trainer @fitgurlmel who really changed my body. When I wasn’t happy with what I saw back in the mirror I spent a whole year training so hard 5 or 6 days a week putting in a lot of work and changed the way that I eat and there’s such a noticeable difference,' Kim said earlier this year.

'I am firm and less cellulite and so much more confident. SO THANK YOU for waking up at 5am to do crazy body building workouts & sprints that I hate & putting me on to this lifestyle.'

Earlier this year Melissa talked about working with the KKW Beauty owner.

She always looks ready for a photo shoot: Kim posed just so as she ran up the beach; the star has been preparing for a new season of KUWTK which debuts this summer

'She loves and hates leg days,' Alcantara told People. 'But she’s committed! She knows what it takes, but it’s also really grueling. It’s heavy, it’s killer, but she’ll be like, Alright, let’s do it! She’s a workhorse.'

So far the trainer thinks Kim is doing a great job.

'Kim has been getting some really nice results, like with her triceps! She can’t believe how much has changed over the last few months. And when you’re in this deep, it’s hard to go back. She just keeps it up. She’s focused and she has a goal in mind.'

Alcantara was also seen on a November episode of KUWTK; Kim found her in 2017 on Instagram.

From the mouth of the trainer: 'She loves and hates leg days,' Alcantara told People. 'But she’s committed! She knows what it takes, but it’s also really grueling. It’s heavy, it’s killer, but she’ll be like, Alright, let’s do it! She’s a workhorse'

'I'm going to start a really crazy diet. I was looking on Instagram and this body builder popped up on my page and she had gained 70 pounds in her pregnancy. Her kid's like 6 now. She is like ripped,' Kim said.

'Melissa is a trainer I found. She's super inspiring to me and I really want to meet up with her and she if she could train me. She could help direct my food and really get me on an amazing path ... If I was 10 percent like her it would be life-changing. Like my whole arms and back. It's mostly food. I gotta have this lifestyle. I gotta try.'

Alcantara is big on 'making food simple,' and eating 'fresh and good.'

So motivated: 'I'm going to start a really crazy diet. I was looking on Instagram and this body builder popped up on my page and she had gained 70 pounds in her pregnancy. Her kid's like 6 now. She is like ripped,' Kim said

Why she loves the lady: 'Melissa is a trainer I found. She's super inspiring to me and I really want to meet up with her and she if she could train me.

I gotta have this lifestyle. I gotta try,' added the petite wonder

And she keeps workouts fun.

'It's a mix. I like low-intensity interval training. I have high-intensity and then weight training.' she noted.

This comes after Kim shared a three-generation photo on social media on Wednesday from her new Fendi ad campaign.

The reality star posted a black-and-white clip on Snapchat showing herself along with momager Kris Jenner, 62, and her five-year-old daughter North West posing at a pool.

The first of five short clips of the famous trio was released on Tuesday as part of the Fendi campaign with the song Love Lockdown by Kim's husband, Kanye West, as the soundtrack.

The image Kim shared on Snapchat was taken from the same photoshoot and showed her sitting on a diving board in Fendi boots while Kris and North stood nearby with a view of Los Angeles behind them.

According to Fendi.com, that particular Kanye song was chosen as the soundtrack to the five videos because the music 'guides the narration and, one episode after another, in a crescendo of emotions, Fendi reveals the deep, intimate and family bond between protagonists.'

The Kanye song Love Lockdown was originally released on September 18, 2008.

The video featured Kim, North, and Kris walking in a field, picking flowers and handing out by a pool while dressed in the luxurious label.

Fendi released the footage to their Instagram, writing: 'Personal, unique, unseen. @kimkardashian, @krisjenner and North West share an unexpected view of their relationship for #MeAndMyPeekaboo Chapter II.'

Adding: 'Filmed in Los Angeles, the intimate short video is the first of five set to Kanye West's emotional track, Love Lockdown.'

It included the hashtags #MeAndMyPeekaboo #FIsForFamily and was accompanied by the release of stunning still images of the trio, too.

The campaign marked the 10th anniversary of Fendi's Peekaboo bag; the first chapter of the ad starred Silvia Venturini Fendi and her daughters Delfina Delettrez and Leonetta Luciano Fendi.

The video, shot by Marcus Hyde, starts off with Kim and North in a field of grass as Kanye's song begins.

The video then shows Kim's outfit from head to toe - which included her thigh-high logo boots - and the iconic Peekaboo purse.

Along with the boots and purse, Kim donned a button up shirt and black denim, with her long brunette locks loose with a slight waves.

In the final bit, Kris and Kim pose on the diving board of the pool before heading inside the home, where they strike another pose.

According to Fendi.com, Kim said the Peekaboo handbag 'is timeless because it's so simple,' adding that it's 'a classic bag you can wear no matter the occasion or season. That's why I chose the Peekaboo, because it's classic but also modern.'

The KKW Beauty founder said: 'Fendi represents a strong and determined woman.'
