The Canadian has broken 19 powerlifting records and still holds nine of these.
The 51-year-old splits his time between weightlifting and caring for his congregation at St Paul's Evangelical Lutheran Church in Cobourg, Ontario.
His other records including pulling a fire engine over 100ft and the most cabers tossed in three minutes.
Rev Fast lives in Cobourg and spends his free time competing in weightlifting competitions.
He donates all his winnings to local charities.
According to the Daily Mail, he said: "I've set many records over the years - I've pulled planes, trucks, ships and trains. Just about everything you can pull.
"About the only thing I haven't pulled has been muscles. I've been competing at an extreme level for 21 years and don't want to stop now.
"I've been given the ability to do this and I believe it is a gift from God. The deal with gifts like this is you have to use them to help people otherwise it would be ungrateful.
"So with all my world record attempts I've always tried to raise money for charity."
In one challenge alone, pulling a plane, he made $65,000 for charity.
Describing that feat, he told the Daily Mail: "I was pulling and pulling the plane for about 45 seconds before it even started to move.
"I was completely exhausted - I couldn't feel my muscles any more, but my mind just took over. I pulled with everything I was worth and eventually it started rolling."
The priest also said he was planning to continue his weightlifting in a bid to break more records.
