How does 58 pull ups in one minute sound to you?
The personal trainer completed 58 pull ups in just one minute, surpassing a Guinness World Record of 50 pull ups, held by US marine, Michael Eckert.
A second world record of 105 pull ups in three minutes, surpasses a record of 100, which was set at a strongest soldiers contest in Vietnam back in 1988.
Mr Heer attempted both records in Hounslow at the beginning of the year, before sending them in to RecordSetter, an online world record community.
RecordSetter invites anyone and everyone to send in a video of their world record, before sharing records on their website.
Rules are laid out for each individual challenge, which for Mr Heer's challenges included the use of a steel straight bar, and no leg movements were allowed during the attempt.
Talking to getwestlondon, Mr Heer said: "Doing these records wasn't easy at all, I failed more times than I succeeded but it was always a case to strive for progress not perfection till I finally settled with those numbers.
"People called me crazy in my attempts and my routine but I thought maybe what IS crazy is that we don't live to our full potential despite how powerful we can potentially become by the act of simply doing.
"And it's okay to be called 'crazy', because the greatest oak in the forest was once a little nut who held its ground, you see if you make excellence a habit then the idea of greatness is personified."
