Rob Kardashian's hard work at the gym is paying off. The reality star has been open with his fans about his weight loss journey since gaining 100 pounds between 2014 to 2015 and being diagnosed with diabetes, and the youngest Kardashian is continuing his transparency with his latest Instagram post.

Kardashian took to his account to share a side-by-side photo of himself from June 2015 and now, and the comparison makes it clear just how far he's come. "LOL!!" he wrote alongside the 'gram with laughing emojis. "Still got a lot of work to do and weight to lose but glad I'm getting better :):):)."

His positive attitude could be attributed to his fiancé, Blac Chyna, who has been very supportive of him as he puts in the work to shed the weight and get healthy again. She regularly documents the nutritious meals she whips up for him on her Snapchat. Teamwork makes the dream work.

Earlier this month, Kardashian announced that he is expecting his first child with Chyna, and the duo is very excited about their new addition. Chyna shared the first ultrasound of their baby on Instagram this week along with a heartfelt message telling fans to believe in fairytales. They're certainly on the way to happily ever after.
