Britain's Duke and Duchess of Cambridge and Prince Harry have launched their new mental health campaign.
The trio kick-started their new endorsement Heads Together, which is made up of seven charities, at the Queen Elizabeth Olympic Park in London on Monday morning (16.05.16).
The duchess was keen to get stuck in straight away and slipped into a pair of boxing gloves as she tried her hand at boxercise before being encouraged to punch hand pads held by former professional boxer Duke McKenzie.
The brunette beauty and two princes have used their Royal Foundation to set up the campaign in a bid to end the stigma surrounding mental health once and for all.
Heads Together also hopes to raise £1 million through participants in the 2017 Virgin Money London Marathon.
A spokesman for Kensington Palace said mental health is an important issue for all three members of the royal family.
He added: "They realise that the underlying factor in addiction and homelessness is often mental health."
As well as Heads Together, Prince William is working closely with CALM - campaign against living miserably - in a bid to lower the amount of male suicides by encouraging men to speak out about their problems before it becomes too much.
The duchess is the patron of the children's charity Place2Be, which aims to support youngsters struggling with mental health by providing them with in-school counselling.
And Harry - who has just finished the Invictus Games in Florida - focuses on mental health of the Armed Forces.
