It's paying off! Khloe Kardashian reveals her VERY shapely derriere in skintight gym leggings (Photos)

Khloe has worked her way to an extremely impressive physique, and Khloe Kardashian is seriously keen to keep it that way. Just after revealing her stunning Women's Health cover, the 31-year-old Keeping Up With The Kardashians star was seen hitting up the gym in Beverly Hills on Tuesday. The TV personality showed off her incredibly shapely, pert derriere and sculpted legs in a pair of black athletic tights which she paired with a clinging black T-shirt and funky cropped red and black jacket. The t-shirt underneath the funky Adidas jacket was also cut low enough for the star to reveal her ample cleavage. Khloe appeared to be wearing a full face of make-up, as her eyes were concealed with oversized aviator shades. Her blonde locks worn long and loose, after previously having stepped out with her tresses tied up and hidden under a black baseball cap. And, as ever, the star finished the whole off-duty look with a pair of oversized shades. Khloe recently admitted that all of her hard work is part of a revenge plot. Covering the new issue of Women's Health, the star wears nothing but an unbuttoned top and panties (without a bra) as she reveals her motivations for getting in shape. Talking about the challenges of beginning a workout regime, she said: 'The first 45 days you're like, "F**k this s**t." You're exhausted, you're sore, and I actually felt fatter because I was swollen.' However,she revealed there is light at the end of the tunnel: 'If you keep going, you're eventually like, "Wow, is that an indentation on my arm?"' 'Yeah, it's a revenge body,' she admitted. 'But it's just as much for all my critics who called me "the fat one" for my entire existence.' Regarding Khloe's 'revenge body', it was just last month that she told Complex: 'I never looked at myself as the fat sister. Sometimes I would beat people to the punch and say, “Oh I'm the fat, funny one,” because that's what people would say about me. 'But I never really thought that. Looking back, I do believe I was unhealthy, but at the time I really thought that that was as skinny as I was going to get. 'You know, everyone's like, "You're big boned." I have childbearing hips. You're like, "No, you could still lose some weight."' MORE PHOTOS AFTER THE CUT...
