Go Underwater Rock Running
If you are looking for an extreme workout that improves your overall endurance, this activity is for you. Athletes from any sport can benefit from underwater rock running. Start in the shallow end with a smaller rock and work your way up to rock-running glory as you clutch a giant boulder in your arms and majestically sprint across the ocean floor.
Being submerged in Hawaii’s spectacular, blue ocean water, places resistance on all sides of your body, forcing opposing muscles to work equally. This is an invigorating form of cross-training that has been adopted by many professional athletes.
