In video uploaded to Wheels’ Instagram, Crowley is seen lowering the barbell – loaded with 220kg of weights – towards his chest.
In mere seconds, Crowley’s pec pops and he jumps off the bench.
Crowley told his followers on Instagram that he was admitted to the Kings College Hospital in Dubai and booked into surgery.
“Cannot believe it happened, completely tore my pec tendon off the bone,” he said.
“I will be having surgery today at 5pm, praying that it gets it shape back and doesn’t ruin the rest of my career in bodybuilding before it’s even started!”
Wheels took to Instagram to share a GoFundMe page to raise funds for Crowley’s surgery, revealing that the UK bodybuilder’s insurance did not cover his medical expenses in Dubai.
To date, the fundraiser has already raised over $US38,000.
However, Crowley’s surgery was more complicated than earlier anticipated.
“I had my surgery last night and am now recovering,” he shared in a separate update.
“The surgery was only meant to be 1 hour but unfortunately took 4 hours.
“It took longer than expected because Dr Shine had to completely reconstruct my pec as I tore the tendon off the bone and then the muscle off the tendon.

“Dr also had some issues re attaching the tendon due my bones being so dense, my bones broke the tools used to re attach the tendon.
Crowley revealed on Thursday that he has been discharged from hospital and is now recovering back at his hotel in Dubai.
“An incredible thankyou so much to everyone who has been involved and supported me in this terrible time, it’s been extremely devastating, painful and very mentally and physically impossible, but I’m keeping as strong and positive as I can,” he said.
“I’m still in a lot of pain right now, my whole body is swollen from my toes to my hands, my stomach is extremely bloated and literally has a sack of fluid and inflammation, which literally wobbles as I move.
“The biggest thank you in the world to my little Meggie for being by my side 24/7 since this happened and hasn’t left my sight since, from helping me move to feeding me and keeping me calm.
“She is an absolute star and I need her forever by my side.”
Crowley’s mishap comes just a few months after a Russian powerlifting champion suffered horrific injuries while attempting a 400kg squat at the World Raw Powerlifting Federation Championships near Moscow.
Alexander Sedykh, the reigning champion of the lift, was rushed to hospital after he collapsed while attempting to push up the monster weight in August last year.
