Khloe Kardashian has gradually lost an impressive 40 pounds and is continuously working on maintaining her physique. However, a source has revealed she is worried about her success in the long-run due to the constant maintenance required.

The source, who says she essentially feels trapped, added to Heat magazine: “Khloe is starting to feel the pressure of keeping the weight off.

She’s never had to work this hard in her life. She’s really proud of what she’s achieved but she’s just not sure she can sustain that level of fitness.

The idea of getting up and doing over 100 stomach crunches every morning for the rest of her life makes her feel physically ill. She’s always had huge body hang ups and promised herself she’d get rid of the ‘chubby’ label.

Getting in shape was her ultimate revenge on the people who dissed her – but where does she go from here? She wants her life back and is questioning if being thin is worth it.”

The 32-year-old star is now worried about her situation after having spoken so highly of herself in the past. She is particularly concerned about various unforeseen events, including a future pregnancy or injury while working out.

“Khloe’s workouts are insanely tough. She does rower sprints, med-ball slams, sled pushes, back squats, endless stomach crunches, dumbbell lifting and lunges. It takes everything out of her and doesn’t feel sustainable.

What if she gets pregnant or suffers an injury? But now she’s talked about her weight loss so much in interviews, and basically body-shamed her old self on social media, she’s stuck. She feels really trapped.”
