LAKE NOCKAMIXON, Bucks County, Pa. -

You've probably seen it on lakes or in the ocean, and now we're trying it out for a Fitness Friday:

Stand-Up Paddleboarding. It's like surfing meets kayaking and lets you walk on water!

The LL Bean Outdoor Discovery School has been teaching stand up paddleboarding (SUP) classes at Lake Nockamixon in Bucks County for the past three years.

The manager of that school, Steve Johnson, says they've seen a huge increase in interest because it's a great way to get exercise while having fun and enjoying the scenic lake.

He says you work almost every muscle in your body, especially your core!

LL Bean offers different level classes that include all the equipment you need (paddleboard, paddle, life jacket, and water shoes), and they even have a SUP yoga class and a sunset paddleboarding tour!

To find out more or book a class, go to the LL Bean Adventure website and select the Center Valley store, or you can call 1-888-552-3261.
