Sibling love! Kim Kardashian is cheering on her brother, Rob Kardashian, as he works toward his fitness goal. “His mom and sisters — especially Kim — fully support his progress now,” a source exclusively told In Touch. “It’s still an uphill battle, but Rob is determined to show all the haters that he’s not down for the count.” The 32-year-old has retreated from the spotlight in the past couple of years, and it seems like it might stay that way for a bit longer. “Rob still has a way to go,” the insider added. “He still prefers to wear black and stay out of the limelight.”

However, the sock designer “has slimmed down a bit,” the source explained. “He feels better about himself, and that’s amazing.” It’s no surprise that Rob is thriving these days since he revealed in July that he was spending more and more time at the gym. “Deadddd,” he captioned a photo of weights on Twitter at the time. Of course, fans couldn’t help but show the reality star some love on social media. One person wrote, “Keep up the good work!” while another echoed, “NO PAIN, NO GAIN.” A third person chimed in, writing, “Stay focused, know you can do it!”

The Keeping Up With the Kardashians alum first got candid about his fitness journey in June. “Day 1 all good,” he captioned a snap of the gym at the time. Not only is Rob’s family rallying around him, but Perez Hilton — who has also lost a lot of weight recently — shared his insight with the E! personality. “Don’t expect too much quickly, Rob,” the 41-year-old blogger wrote. “Slow and steady truly does win the race! Be consistent! #RobKardashian #DreamKardashian #BlacChyna. The best advice I can give you is … don’t weigh yourself! Don’t be ruled by or obsessed with a number. Just be consistent with your healthy eating and being active, and you WILL get results!  You got this!”

Rob — who shares his daughter, Dream, 2, with his baby mama, Blac Chyna — seemed to appreciate the tips. “Yes, I don’t weigh myself just yet, LOL, and I really don’t care about the numbers — just want to the healthy and that’s all. Thank you for your encouraging words. I appreciate you.”
