Do a beach or park workout.

“A couple of months ago, I found myself on the sandy shores of Oahu, being told to run down the beach and back up while carrying a 15-pound sandbag. The trainer instructing our small group was Samantha Campbell, C.S.C.S., who trains the Red Bull–sponsored big-wave surfers on that very same beach. Campbell had us doing conditioning exercises, running with sandbags, throwing the same sandbags back and forth to a partner, and hopping in and out of an agility ladder. All barefoot, all on the sandy beach. It got me thinking: Am I going to be extra sore tomorrow? I was doing exercises that I’ve done before on solid ground, but everything felt like it required more effort. My quads were really feeling it, and I was out of breath pretty quickly.”

“Waking up early has its perks on the beach because as I set out to complete a beach workout this morning, I saw the sun rise. It was a romantic moment… with myself. I absolutely loved the workout I did this morning and I basically made it up after I started running. I knew I wanted to run on the beach, but I wasn’t in the mood to only run and figured I could work a few circuits into my workout. I felt a little funky doing the circuit as people walked by, but I’ll probably never see them again in my life.”
