Back at it! Khloe Kardashian hits the gym after jetting home from Australia... as it's claimed she plans to start a fitness line

Before landing on the cover of Complex magazine, Khloe Kardashian was criticized for her weight and admits she was even cruelly dubbed ‘the fat one’ out of her sisters.

But since the sultry shoot, which is featured in the August/September issue of the magazine, the 31-year-old reality star has silenced her haters and publicly opened up about her new-found love for fitness.

Now she’s back from a recent trip to Australia, and the youngest of the Kardashian sisters proved that she’s not slowing down with her exercise regimen as she was spotted hitting the gym on Monday in Beverly Hills.

In slim-fitting leggings and a matching black long-sleeved shirt, Khloe enjoyed a post-workout shake as she left the gym.

She also wore a red flannel, which she tied around her waist and a San Francisco 49ers cap with aviator sunglasses.

With her gear loaded up in a camouflage backpack, Khloe was joined by her bestie and frequent workout partner, Malika Haqq.

During a recent trip to Australia, Khloe spoke with radio hosts Fitzy & Wippa about her workout routine and how despite jet-lag, she was able to find the energy to break a sweat.

‘It wasn't that intense here because I'm still jet-lagged, but I make sure that I go, she said. ‘Even 30 minutes you feel, “Okay, I feel good about myself.” Then if you want to eat something or whatever, then you don't feel as bad.’

‘Definitely when I'm in L.A., I go hard, and I've lost like 35 lbs,’ the Keeping Up With The Kardashians star revealed.

And an Instagram photo, posted last Thursday, proved that the 31-year-old was in fact working out during her trip.

The snap shows Khloe and her workout buddy Malika Haqq in the midst of a Pilates session.

Khloe captioned the picture: ‘Even down unda and jet lagged, we will find a fitness class.’

And Khloe’s new-found love for fitness doesn’t end with an increase in trips to the gym.

The Fix reports that the reality TV star is looking into starting her own line of fitness attire.

‘She wants to design a line that is dry fit clothing, but better, sexier and a bit wild,’ a source told The Fix. ‘She thinks people should show a certain side of themselves while working out.’

‘She thinks the current stuff is so boring,’ continued the source. ‘She thinks that if the workout clothes were sexier, it would make people want to work out more.’

The photos don’t lie – Khloe has certainly been taking her workouts seriously.

In her Complex photo shoot, the 31-year-old flaunts her enviable hourglass figure complete with a svelte waist and voluptuous curves.

And in a recent Instagram snap, Khloe showed fans an un-retouched version of the shoot in comparison to the digitally enhanced with the caption: ‘This one is for all the troll haters out there that cannot seem to give me an ounce of credit for my daily workouts!’
