The main difference between SUP and surfing is that SUP is a standing up paddleboard, and surfing is lying down the board.
SUP is a great way to get a total body workout because you use all of your muscles to balance and navigate the board. It's perfect for people who want to get into shape because it's low impact, and you can easily control how hard you work out by adjusting your speed and intensity. Plus, it's such a fun activity that you'll never get bored!
