His eight-year-old daughter won online acclaim after she was filmed throwing 100 punches in just a minute.
Now, boxer Rustram Saadvakass is passing his fighting skills on to her six brothers and sisters.
The Kazakh family, who live in Voronezh in Russia, train five days a week – often in the woods outside their home – and are taught how to dodge and land blows.
Rustram puts his children through their paces once in the morning and again in the evening, and believes the discipline teaches courage and perseverance.
The seriously-tough family are pictured sparring with each other in the woods and in the gym with eight-year-old Evnika usually leading the way.
Evnika’s proud father spotted her emerging talent when she was just four, and she can now throw 47 punches in 30 seconds with one hand.
Tough cookie: Eight-year-old Evnika Saadvakass won internet fame after being filmed throwing 100 punches in just a minute.
The eight-year-old said: ‘I like boxing because when I throw a side hook and I hit hard, I like the sound it makes.
‘I also like when I’m punching fast and my feet join in.
‘And when I’m doing a combination of punches and I go in fast, fast, fast, leaning in for the hit.’
When a video of Evnika’s lightning speed went viral, Rustram said he was inundated with messages from people amazed by her ability.
He said: ‘When people see what Evnika does they are thrilled with emotion with joy and excitement.
‘They start to point and say that’s the guy who trains Evnika.’
However, Rustram wasn’t expecting such ability to emerge at such a tender age.
He said: ‘When Evnika was four I noticed she was showing these beautiful moves.
‘The first moment I noticed her talent was when I was training with the other kids and she was standing to the side.

‘I was not paying attention to the younger kids but Evnika started doing the task I set for the older ones.
‘She was so attentive and hardworking. It’s a good sign of character. I saw the first spark of what I needed to develop.
‘Even if you are a boy or say a 25 or 30-year-old professional boxer, you will probably admit that many of the moves Evnika does, you can’t do.
‘Because she’s got the speed, the intervals and the start speed, and her feeling and reaction are both at a really high level.’
Rustram and his wife Ania, 38, keep a strict regime with their other kids Ainzha, 16, Rush, 13, Selyavira, 10, Adelaida, 5 and Hatshepsut, 4.
Their one-and-a-half year old son AinziMakassi is also almost certain to be included in the training sessions when he gets older.
Rustram said: ‘I am deeply convinced that work with children should start at an early age.
‘Not only because they understand everything at that age, but because any physical activity imprints into their memory and physiology

‘So later on it will affect their mental capacity. I’m convinced of this.’
But despite the violent nature of the sport, Evnika’s parents aren’t worried by her participation.
Mum, Ania, said: I myself trained in gymnastics and acrobatics and we had many injuries and broken bones
‘I would worry more if Evnika trained in gymnastics than boxing.
‘She feels very confident in the ring and I am not worried about any injuries.’
Rustram has been boxing since the age of 16 and recently developed an invention to help others develop their boxing skills.
The ‘Evnik Simulator’ – named after his daughter – uses momentum to condition muscle groups to increase speed and mobility.
Rustram said: ‘From the beginning of my career I aimed to create a training method based around one component, and that’s speed.

Leading the pack: The father believes eight-year-old’s Evnika’s amazing ability could make her a ‘star’
‘So we invented the training tool, which we call Evnik.
‘It’s what Evnika uses for training.
‘So when she punches, it bends, builds up energy and creates a force on the muscles.
‘And so as the movement continues, kinetic energy building up and allowing you to stretch out your arm
‘And we can do all of them using our training tool. Any punch can be practiced with the Evnik simulator.’
Rustram now has a fundraising campaign on Indiegogo crowd funding website and hopes to move his family to the USA in the future.
He said: ‘I hope that Evnika will never tire of the sport, I hope she doesn’t stop loving it as she loves it now.
‘With her energy an with what she is doing Evnika has the ability to burn, to be a star.’
