A post-mortem ruled she had died from anoxaemia followed by an acute, non-traumatic cerebral haemorrhage, as well as “generalised thromboembolism”.
Anoxaemia is a deficiency in the amount of oxygen in the arterial blood.
The horror unfolded at a gym in Torreón, Coahuila, Mexico.
Ariatna was a nursery teacher and had recently taken an exam to secure a new job.
She was set to receive her results the day she died, as reported by Need To Know.
Ariatna was an animal lover and often shared posts about dogs available for adoption.
Her last social media post read: “It makes me laugh when people say ‘don’t humanise your dog’ when he’s the one who humanised me.”
Experts say anoxaemia can be exacerbated by extreme physical effort.
This suggests Ariatna may have collapsed because she was squatting too much weight.
Her mother, Selene Esparza, wrote on social media: “My princess, my girl, you’ve gone and left us with empty souls and shattered hearts.
“Fly high, my love, very high.
“Here on earth, you were already a light guiding those who crossed your path, and now you are a light illuminating the angels.
“I love you, my princess.”
