Since 2007, Casi Rynkowski has been living her dream training athletes, fitness enthusiasts, and those who want to live a healthier lifestyle. Her passion for fitness outdoors exploded when she launched her adventure fitness business, exposing clients to the idea of fitness outside four walls. Surfing, stand up paddling, rock climbing, ice climbing, and winter mountaineering became her new training ground in New England. Her clients not only found new ways to cross train outdoors but discovered new passions in life.

Today you will find Casi teaching paddling classes, conducting clinics and seminars across the US, as well as crafting all kinds of outdoor adventures for fitness enthusiasts. She loves engaging with people of all levels of experience and providing them with quality instruction and the knowledge necessary to build their confidence to step outside their comfort zone.

Casi is an AFAA certified personal trainer, and ACA level 2 SUP instructor. She is sponsored by SIC Maui paddleboards, Werner Paddles, MTI Life Jackets, NRS paddle gear, Unsinkable Polarized sunglasses, Deuter backpacks and Virus Sports Performance athletic wear. Casi fit tips, articles and adventure stories are published regularly in SUPthemag, Standup Journal, Samata Magazine, and Standup Paddle Magazine.
