A lot changed for two-division ONE MMA world champion Christian Lee during his time away from competition that lasted over two years.The lightweight and welterweight king continued to work hard in the gym even when he didn't have a return date in the books.During this period, 'The Warrior' was able to spend months of quality time on the mats with his younger brother, Adrian.The 18-year-old has been an exciting prospect for some time considering the success he had at the amateur level and his family name.At ONE 167, he made his pro debut and in 2024, he was able to produce back-to-back submission finishes to achieve a successful first year in the promotion.In the lead-up to his comeback at ONE Fight Night 26 on Dec. 6, Christian spoke about the benefits he gained from training with his brother. But, of course, for Adrian, getting to train and learn from a world champion has been massive.In an interview with Val Dewar, Christian Lee spoke about how he's able to transfer knowledge that he learned first-hand to his younger brother:"I think it's great that I'm able to take the experience that I've had, fighting since I was 17. So I remember being 18 years old, having that early fights. I'm able to give him a lot of feedback and a lot of little tips from the things I've learned over the years."Watch the full interview below:Adrian is following in the footsteps of Christian LeeWhen you look at what Christian Lee has accomplished in his career, it's going to be hard for anyone to replicate that success.By having his brother in his corner, Adrian has a bit of a head start because he's able to learn from one of the very best who has been in the exact same position before.The brothers being side-by-side only makes them a stronger unit going forward.
