"Heavy duty and safe"
I am also an instructor and trainer and these jump blocks are awesome. I travel a bit sometimes and to just rinse them off and load them in e car is so simple. They are worth every penny!
"Safe Jump Blocks"
As a professional instructor I spend a lot of time moving jumps and cavaletti around! It is so important for elements on the ground to be safe and correctly placed. These light weight, weather proof, unbreakable blocks make it SO MUCH EASIER to create elements and place them quickly and correctly. I know they seem to be expensive but I have collected a dozen over the years and they are so worth the money. Thanks for a great product.
