I'm new to SUP (and obviously new to this forum), cheap, and can only get on the water a couple days a week. I wanted something to help mostly with my leg strength and saw this video awhile back. Didn't want to part with all the money for the whole kit, so I bought the gigante cushion and a rip trainer bunjee for under $100. Made the rest with plywood and a piece of closet pole. It works great for me!
This is a great place for a rookie like me to learn this SUP business, thanks.
