On a recent vacation to the west coast of Florida, It was pretty flat as the west coast usually is, so I decided to give SUP “stand up surfing” a try. It was MUCH harder than I anticipated and really worked a lot of muscles you would not think stand up surfing would effect. It is the complete opposite balance wise than surfing so you spend a lot of time using core muscles to stay up. I am still not sold on doing SUP for surfing as it gives an unfair advantage in the lineup and seems to invite a lot of bad Karma from other surfers. As a workout fitness tool I am completely hooked! When it is small and there is no surf ,grab a stand up board and go on an adventure and get fit at the same time.
