Fresh from unifying three of the four world heavyweight titles, Anthony Joshua has shown that he doesn't stay still for long after clocking up another honour.

Working with Lucozade Sport Fitwater, AJ hosted the world's largest ever Boxercise workout with 541 participants in London's iconic boxing venue, York Hall.

The event was part of Lucozade Sport's commitment to get 1,000,000 people moving more by 2020. The 500 plus strong class was treated to a bespoke Boxercise lesson during which the Heavyweight World Champion of the World demonstrated a variety of combat and defensive moves that each participant needed to follow to ensure they achieved Guinness World Record success.

Speaking after setting new levels yet again, Anthony Joshua said:

"“It’s been really exciting to be part of setting a new Guinness World Records title with Fitwater. To get over 500 people taking part in something I’m passionate about is amazing. I hope our World Record success inspires more people to get moving and involved in Boxercise.”

The record breaking night wasn't the first time AJ and Lucozade have given fans an opportunity to work out with the boxing superstar up close. Earlier this year, AJ led hundreds of fans through a surprise open workout in London.
