Inside Tyson Fury's training camp ahead of Oleksandr Usyk showdown: His dad is back in from the cold, he's transformed into a lean machine despite eating 6,000 calories-a-day and the workouts have been BRUTAL

One of the biggest fights in boxing history, Tyson Fury vs Oleksandr Usyk is just a week away from taking place.

Fury will step into the ring opposite the brilliantly talented Ukrainian on Saturday, May 18 in Riyadh, Saudi Arabia for the unified titles. 

The highly anticipated fight will see two of boxing's biggest giants go toe-to-toe for the right to be called the undisputed heavyweight champion of the world. 

Unlike his fight with Ngannou, which saw the 35-year-old rock up to the ring with little to no preparation, Fury seems to be locked into this training camp and has even brought his dad back into the fold.

Here is a look inside Fury's training camp as the former world heavyweight champion has introduced a strict diet and training regime. 

Look who's back... 

Fury has offered plenty of insight for fans into his training camp over recent weeks ahead of his fight with Usyk and he's brought a familiar face back into the fold. 

Earlier this year, it was revealed that John would not be a part of Fury's camp leading up to the Usyk fight.

During the early stages of his son's camp, John even hit out at 'Camp Fury' over how certain things were handled within the camp ahead of his sons mountainous fight. 

John criticised his sons training method as Fury vs Usyk had to be postponed after the English man suffered a cut to his eye after a sparring session gone wrong.

His father was critical of Fury's training technique as he said he would have handled camp slightly differently if he was in charge - stating he would have done 'body sparring and technical work' ahead of a fight of 'this magnitude'.

'It was a freak accident', John said. 'For my money, I’d have done things a little bit differently, with a fight of this magnitude so close, I’d have been doing body sparring and technical work with some long-range practice, but who am I? I don’t know, do I?'.

Although reasons were not made clear as to why he was excluded from the camp, all seems to be harmonious once again as video footage recently shared on social media shows the two working together again. 

Bringing back his father is not the only action Fury has taking for the fight, he has also followed a new strict meal plan which has seen the boxer get in the 'best shape of his life' according to his dad. 

An incredible body transformation 

Nutritionist Greg Marriott revealed to Men's Health that Fury's new diet sees him consume 3,000 calories on rest days and between 4,500 to 6,000 calories on training days.

The strict diet has been aimed at providing the 35-year-old with enough energy to fuel his intense training regime while also managing his weight. 

His nutritionist revealed that the Gypsy King is eating up to six meals a day under his diet plan compared to previous camps, where he had previously consumed one or two meals a day.

Some of the meals reportedly included in Fury's diet includes having two slices of sourdough toast, avocado butter spread with fresh garlic tabasco and black pepper for breakfast, as well as fresh plum tomatoes and lean beef mince sausages.

Oatmeal and protein with fresh nuts and chia seeds, and omelettes have also been included as breakfasts.

For lunch Fury has recorded himself feasting on chicken, rice and a mixed salad.  

A dinner under the diet plan included a 400 gram filet steak with Dijon mustard, as well as roasted vegetables including broccoli, asparagus and beetroot.

For all of his dietary changes, ultimately, the proof will be in the pudding...

Mystery tweaks to the strategy and a brutal regime

In addition to Fury's nutritional discipline, he's been pushing his body to the limit in training. 

The British fighter has posted regular updates on his social media showing gruelling workouts, including a clip of him shifting huge weight on the leg press machine in the gym, grimacing as he does so. 

In another video he is shown pushing a heavy metal sled along a gym runway, working on both his cardiovascular endurance and leg muscles. 

He also shared footage working on 'speed and power' on the pads being held by his father while training in San Francisco.   

Tyson Fury's trainer also revealed that 'adjustments' will be made for his clash with Usyk in Saudi Arabia. 

Some in the boxing world have been outspoken over concerns that Fury may struggle to deal with the Ukrainian's southpaw stance however his, trainer SugarHill Steward, said that won't be the case.

According to ProBox TV, he said: 'I haven't changed anything in that respect. I wasn't in his corner for the [Otto] Wallin fight, and we've not faced a southpaw since, so there wasn't anything to change.

'It's about adding something extra to what he already has. Tyson has a great mind and he's very intelligent, he is one of the best.

'The Wallin fight he won anyway, the problems he had were from the cut he had on the night.

'I'm not going to tell you what I'm going to change, obviously. I can't be giving away our game plan for the Usyk fight. [But] I will be making some adjustments.'
