Kate Cassidy showed off her incredibly toned abs as she slipped into skimpy 437 workout gear for an event to promote the brand on Thursday.
The influencer, 26, was plunged into grief after the death of her boyfriend Liam Payne at aged 31 last October after he fell from a third floor balcony at the CasaSur hotel in Buenos Aires.
Kate looked sensational as she took to Instagram Stories in a tiny white crop top and matching shorts while pumping weights.
The event saw the stunner joined by pals as they built up a sweat with a string of exercises including lifting a heavy medicine ball.
Poking fun at her abilities she cheekily wrote: ‘Look at how strong I am lifting those 2lbs dumbells’.

Earlier this week Kate discovered a previous social media tribute to her beloved Liam had been shared 4,444 times.
Uncannily, it is remarkably similar to the 4:44 figure adopted by the couple as their ‘angel number’ prior to his sudden death.
Drawing attention to her shares and their likeness to the angel number on Instagram, Cassidy, 26, wrote: ‘Hi Liam.’
The mystical figure has several hidden meanings behind it and is considered an angel number in numerology.
Angel numbers are repeating sequences of digits, normally in sets of three or four, and they are believed to hold spiritual guidance.
While 333 symbolises growth and 555 represents change, 444 has its own unique meaning behind it.
In numerology, 444 is a sign that the ‘angels are with you’ and are ‘there to guide you step by step’.
The way the figures are formed means they represent stability and a reassurance that you are not alone.
Numerology expert Sunny Dawn Johnston told Glamour: ‘When you see these numbers, know deep within that the angels are speaking to you, guiding and supporting you.
‘It’s a blessing to be in such direct communication with the divine.’
Kate had originally flown with Liam to Buenos Aires while he renewed his visa and watched his former One Direction bandmate Niall Horan’s concert in the city on October 4.
However, the late singer stayed on in the Argentinian capital after she flew home on October 14.
He tragically died two days later after falling from his hotel balcony while under the influence of class-A drugs and alcohol.
Following his death, Kate added ‘444’ to her emotional tribute to her ‘angel’ boyfriend and shared a snap of a note where the singer had written the numbers.
It showed the former One Direction band-member’s fascination with ‘angel numbers’ and ‘manifesting’.
Kate revealed that she and Liam had been ‘manifesting their lives together’ – a longing heavily associated with the number she signed off her tribute post with, ‘444’.
She told her followers that she had been at a ‘complete loss’ following the tragedy and that ‘nothing about the past few days had felt real’.
The American influencer then posted the sequence ‘444’ in the bottom right-hand corner of the tribute next to a red heart emoji.
TJ Higgs revealed the meaning behind the sequence, saying: ‘The angel number 444 signifies protection, encouragement, and support from the spiritual realm.
‘Seeing this number repeatedly suggest that you are on the right path and that your angels are surrounding you, offering their guidance.’
She added: ‘Many people find comfort in angel numbers during difficult periods, as they can symbolise hope and reassurance. For instance, seeing 444 may remind individuals that they are not alone, and that support is available.
‘By interpreting these numbers as messages of love and guidance, individuals may feel a sense of connection to something greater, aiding in their healing process.
‘When Liam Payne wrote his note to his girlfriend Kate, with the significance of angel numbers 444, I genuinely believe he was fully aware of the love and support surrounding him.
‘He understood that he had people in his life who made him feel, loved cherished, valued, and important.’
