When Sebastian Musson climbs walls with one hand, he knows it looks like he is redefining the impossible.
The four-time British Para-climbing champion is focused on winning an historic gold medal when the sport features at the Paralympics for the first time at the Los Angeles Games in 2028.
Competing there would mark an incredible high for the 19-year-old from Long Eaton who has quickly scaled to third in the world rankings after a chance encounter at his local climbing centre in Derby got him into the sport just six years ago.
Until he was approached by Anita Aggarwal, a British Para-climbing champion who works as an inclusive climbing coach, Musson hadn't considered the possibilities open to him.
But not only did he quickly realise what he could be capable of, so did climbers around him and just about every bystander that has caught a glimpse of him in action.
"It's being able to do something that people don't expect you to be able to do when they see that I've got one hand," Musson told BBC East Midlands Today.
"I go up climbs where people themselves can't go up, and I'm doing it without a hand.
"It's just something that is inspiring to other people and I absolutely love doing it."

Musson knows what it means to be inspired.
He was only four years old in 2012 when he watched the Olympic and Paralympic Games in London and made what has turned out to be a life-defining statement.
"I said to my parents 'that's what I want to do, I want to go to the Paralympics and I want to win gold'," he said.
Musson smiles when talking about it because for more than a decade he admits he "didn't have a sport" to focus on despite his grand ambition.
But in Para-climbing, he has found a way to try to ascend to Paralympic glory.
"I'm taking it all the way and going to go achieve that dream," he said.
"I am very much thinking about LA and aiming for the gold medal."
In 2024, Musson claimed his first international medal when he won silver in the AU2 category - for athletes with moderate upper-limb impairments - at the European Championships in Villars, Switzerland.
He has since collected bronze medals at World Cup events in Italy and the United States.
And all the success so far can be traced back to a rainy day in 2018 when Musson was forced indoors instead of attending his usual rugby union training session.
It was soon after that Aggarwal spotted the novice and asked to coach him.
"Instead of just sitting around at home, my dad suggested we go climbing, so we did. And after the first session I was absolutely hooked," Musson said.
"It was the second time we went that I met Anita. The impact of meeting her I don't think I could comprehend at the time. If it wasn't for her, I don't think I'd be climbing right now, especially in the situation that I'm in now."
'How you get up the wall is up to you'
Musson's coach turned international team-mate Aggarwal, who lives with multiple sclerosis, describes climbing walls an as an "adult playground" where participants are not limited by rules or their physical traits.
"It's really welcoming environment because all we've got is puzzles on the wall, and the idea is to break the puzzle," she said.
"My team-mates are armless, legless, blind and neurological and they can still climb better than me and they're missing limbs or they have no eyes.
"From an inclusive point of view there is no exclusivity because there's no rules in climbing. The only rule is can you put one or two hands on the top hold? How you get there is entirely up to you."
When Aggarwal first saw Musson on a climbing wall, she said she "couldn't help" but approach the youngster and encourage him to get involved in the coaching sessions she was running.
There were things that had to be learned and adapted to when Musson started training with her - the tying of shoelaces with one hand among them.
It is something they both reflect on with a laugh - with Aggarwal saying he just "didn't twig", but Musson quickly found a solution in velcro shoes.
And now, the athlete Aggarwal says "didn't know he was a Para-climber" when they first met is aiming to become a trailblazer on a global stage in LA.
"I've seen how much it's changed him from being introverted, really quiet and hiding his arm, to now being a really outgoing person teaching other kids and competing for his country," Aggarwal said of Musson'
"He's got expectations and goals and it's just been amazing."
