They both arrived at the arena at 8:30am and had to wait at the front gate before they were allowed in to start jumping.
Mr Engelbrecht said the indoor park had so many different features, which kept them entertained for hours.
There are dozens of trampolines where people can jump and do flips or tricks off the wall or in to the foam pit.
"I have a trampoline at home but it is nothing like the ones here. I wanted to see what tricks I could do as it's so safe, my tramp at home doesn't even have padding."
Mr Engelbrecht said he felt like he could do everything and anything and managed to pull off a triple front flip in to the foam pit.
"I had never done that before so that was pretty cool and it was good as the landing was soft even if you landed on your head it didn't hurt."
The staff also got behind him and gave his last hour of jumping free.
Owner Rebecca Varcoe said he just kept coming back for more and with the hot weather he must have got a good workout.
Mr Engelbrecht said he didn't feel the burn until later that evening when he stopped moving around.
"I guess the adrenaline was pumping when I was there but when I started to rest at home I felt a bit of pain. It won't stop me from going back again today though."
The passion for trampolining started when he was 14 but due to other commitments he has never pursued it competitively.
Now working at Razos Engineering, Mr Englebrecht said he would struggle to find the time so was planning on making the most of it until he started back next month.
Mrs Varcoe said the opening day went well and they were looking forward to a busy January.
