Khloe Kardashian has been nursing an injury for two months.

The 39-year-old reality star has been unable to exercise as hard as she'd like because of the mystery ailment, but she has been working her way back to full fitness "little by little" and hopes to be fully recovered in "a few more weeks".

Khloe took to Instagram over the weekend to share a video of herself enjoying a session with personal trainer Don Brooks, which she captioned: "I hurt myself and couldn’t workout the way I wanted to for almost 2 months. Working my way back little by little

"A few more weeks and I’ll be there.

"Then- I have to stay ready so I don’t need to get ready (sic)"

Khloe recently revealed she works out five days a week, typically opting for "cardiovascular intervals with weightlifting".

And after discussing how she'd overcome her problems with "emotional eating", she feels happier than ever with her body.

Speaking on the 'SheMD' podcast, she said: “I love it. If I’m getting ready for a shoot, I’ll do Pilates and my workouts.

"But now that I’m in a good place, body-wise, that I like, I do sort of eat what I want, but because my brain is so trained, you don’t even want half of the c*** or junk.

“Something like pizza is my weakness. But now that I am in this different state of my mind, I’m never going to eat a full pizza. It’s retraining your brain. If your brain isn’t trained with your body, then you’re not doing anything. It doesn’t matter.”

The 'Kardashians' star - who has True, six, and 21-month-old Tatum with former boyfriend Tristan Thompson - admitted it took "years" for her to be happy iwth her weight.

She said: “I used to be overweight a lot of my life.

“God, I mean my weight-loss journey. It took years for me.

“I’ve always been chubby — like athletic. I’ve always played sports. I just was never in shape."
