MADCAP student James Saward-Anderson has entered the record books by smashing an eye-watering challenge.
In a bid to raise £10,000 for WaterAid the 22-year-old swung a 16kg kettlebell 780 times in an hour – which is equal to lifting 12,480kg.
The previous world record was 12,000kg.
In front of a crowd at the University of Portsmouth, James feared he would not make it.
He said: ‘I’m not going to lie, it was really, really tough.
‘I was under a lot of pressure to succeed and I’d spent a lot of time organising, making sure everything was going to be alright on the night. It left me quite stressed and anxious.
‘Starting off, I don’t think I was in the best mindset and at times it felt horrific. My right leg really started to hurt.
‘It was a battle and at one point I didn’t think I would do it because I was quite far off.
‘But it was a case of gritting my teeth. I was so happy when I made it, although I think I can do better.’
James, of Clarendon Road, is no stranger to tough stunts.
In 2011 he ran 800 miles from Canterbury to Rome.
He then ran a marathon along Southsea beach, submerged in 16 inches of water while lugging a 90lb rucksack.
He has also climbed up stairs covering 5.6 miles in 21 hours, somehow finding time to do 2,000 press-ups on the way.
The aim of the incredible series of challenges is to help WaterAid, a charity aiming to improve water sanitation and availability in third-world countries.
He has raised £1,600 so far and is desperate to meet his target.
The international development student said: ‘For me it’s just a small celebration and then on to the next challenge.
‘I will have to think up something really big to hit my target.’
