Brazilian model Alessandra Ambrosio does some paddleboarding in Hawaii. Stand-up paddleboarding is an increasingly popular water sport and a fun family activity. Paddleboarding skill levels are pretty standard for people of all ages....you just need to stay balanced on the board. It is easier for women because of a lower center of gravity in female bodies. Gliding along on water, while enjoying the outdoors is a fun way to lower mental stress.
