Chris Wall, a 41-year-old soon-to-be father, credits the life-saving actions of his gym owner for surviving a sudden cardiac arrest during a workout class. In June 2025, while attending a high-intensity session at Catalyst Training in Cirencester, Gloucestershire, Chris collapsed mid-class. The gym owner, Robin Oakley, immediately recognized the emergency and acted swiftly, administering CPR and using a defibrillator which was crucial in saving Chris’s life.
Chris was halfway through Robin’s metabolic conditioning class on a Saturday morning when he unexpectedly collapsed. Despite having felt slightly breathless earlier, he had no warning signs that something serious was imminent. Robin, 39, relying on his previous experience dealing with cardiac emergencies, instructed class members to retrieve the defibrillator and call emergency services while he performed CPR continuously until paramedics arrived.
Chris received five defibrillator shocks and nearly 30 minutes of CPR before he was airlifted to Bristol Royal Infirmary for treatment. Experts from the British Heart Foundation note that out-of-hospital cardiac arrest survival rates in the UK are below 10%, but rapid CPR and defibrillation can double the chances of survival. Defibrillators are user-friendly, providing clear voice instructions, and free resources like the BHF’s RevivR app teach CPR in just 15 minutes.

After three days in hospital, Chris learned his cardiac arrest was caused by a plaque rupture leading to a dangerous clot blocking blood flow to his heart. Recovery was challenging, involving physical discomfort and mental hurdles. With the support of his partner Nikki and the gym community, he made lifestyle changes such as quitting smoking and moderating alcohol intake. Slowly rebuilding his strength, Chris returned to the gym and is now training for the British Heart Foundation’s London to Brighton bike ride.
As Chris approaches the anniversary of his cardiac arrest, he prepares to welcome his “miracle baby” and take on the 54-mile charity ride. His experience underscores the lifesaving power of quick response and knowledge of CPR and defibrillator use in emergencies.
