Rob Kardashian is back, and he is healthier as ever!

After hiding from the media and showbiz life for years, Rob Kardashian has been going on public more, especially on social media and around town in the past few weeks. According to a source by People, the "Keeping Up With The Kardashian" star got his newfound confidence because of his renewed commitment to health and fitness. 

The said People source also shared that Rob has been trying to work out more and has had healthier options for him to go for. Staying fit and healthy has made the star feel better about himself, and now, he wants to be "out and about" more often than usual in the past years.

Rob was also seen in Halloween celebrating with his family. The 32-year old star showed off his trimmed-down figure --- and it was all over social media!

Rob celebrated the holiday with his daughter Dream, and the father-daughter wore matching Halloween outfits: Rob as Papa Troll and Dream as Poppy Troll from the DreamWorks' film.

After years of hiding from the public eye, Rob was also photographed and seen outside a club after his sister Kendall Jenner's Halloween-slash-birthday party. 

Rob's family was thrilled to have him back again. Kendall Jenner also expressed how Rob's presence at her birthday party was the "best present ever" the model could ever ask for.

However, it took Rob quite some time to get to where is right now.

In 2016, Rob shared in an interview that the reason he went off camera in KUWTK is that he feels uncomfortable with his weight and skin.

In the past years, Rob has been through ups and downs about his health condition. It was a very concerning situation for the star, and he chose to disconnect from the world because he knows he is not mentally well. His weight gain has been a huge problem and it made the star miserable.

It took Rob a lot of work and effort to get the weight off, and it was a huge mental and physical challenge for him.

Rob went to Twitter in June and shared he has been starting a new fitness regime. In the tweet, the star shared a photo of a  gym that was surrounded by ropes, a weight bench, and multiple resistance machines.
