It's been over a month since Rob first revealed that he was once again hitting the gym, and a source tells ET that the reality star "has been taking his health seriously and has been working out and eating better."
"Rob wants to be around as long as possible for his daughter, Dream, and in doing so, knew he needed to take control of his health," the source adds.
The 32-year-old clothing designer and father of one commemorated the first day of his exercise training with a post to Twitter, showing the inside of his gym back on June 17. About a month later, he shared another pic of his gym's free-weights rack, which he captioned, "Deadddd."
The source tells ET that the efforts have been effective, and he's going to be sticking with it to get in even better shape and stay healthy. "Rob has lost some weight, but has a long way to go," the source shares.
"Rob and Chyna co-parent and are in a good place, but don’t communicate much," the source shares. "They want what is best for Dream and that starts with not having any drama."
The Keeping Up With the Kardashians star has faced challenges with his health and weight over the years, but in January, a source told ET that he was “happier” and “getting healthier” while focusing on fatherhood.
