16-year-old boy hailed a hero after saving man's life at NRG Gym in Sheffield
Mohammad Zakir, a student at Fir Vale School and a long-time member of the cadets, was visiting NRG Gym in Sheffield when he noticed something was wrong.
He had only just walked in, tired after an exam, when he saw a man collapsed on the floor.

“I could see straight away that he was pale and his breathing was really shallow,” said Mohammad.
“There was someone with him on the phone to the ambulance, but I knew I had to do something. I told them I was trained in first aid and they handed me the phone.”
Paramedics on the other end of the line told Mohammad he would need to begin chest compressions immediately.
“In that moment, all I felt was adrenaline. But I knew it was up to me to save this man’s life - I remembered my training and acted as I had been taught,” he said.

Following the machine’s instructions, he continued chest compressions for seven minutes until the ambulance arrived.
“It felt like an eternity, but I just focused on doing everything right,” he said.
Mohammad has been part of the cadets for five years and is now a staff sergeant, helping teach younger students life-saving skills every Wednesday after school.

Following the incident, he is now working with NRG Gym and the cadets to set up a first aid workshop at the gym - hoping to inspire others to act in emergencies just like he did.
Although he has not yet received an update on the man’s condition, police told him he could have saved his life.
Mohammad, one of six siblings, says his parents are incredibly proud.

Hide AdNaz, the manager at NRG Gym, said she wasn’t there when the incident happened, but was overwhelmed when she heard what Mohammad had done, and called him in immediately to thank him.
“Given his age, it’s so amazing that he acted in such a heroic way. His quick thinking and actions are something even many adults would struggle with.
“To say I’m proud is an understatement. He’s a true inspiration - not just to other young people, but to our whole community.”
Naz added that the gym has given Mohammad a free year-long membership in recognition of his bravery.

She also highlighted how meaningful it is to see such positive stories coming out of areas like Pitsmoor.
“This is a deprived area, and we need to hear more stories like this,
“The fact that a young boy from Pitsmoor did something so incredible — it means so much. He’s part of a new generation that’s going to make a real difference.”
Naz said she even phoned Mohammad’s mum after the incident.

Building community through action
NRG Gym prides itself on being a welcoming space for all, offering memberships to children as young as 12 if accompanied by an adult.
Now, with plans for a community-first aid workshop, Mohammad’s actions could inspire even more young people in Sheffield to learn the skills that save lives.
And as for the teenager himself?
