CrossFit Boynton Beach
The functional rig in the middle of CrossFit Boynton Beach's bare-bones gym looks a little like a jungle gym. That's appropriate, because the facility's certified coaches lead classes that are a little like play time. Their charges swing from gymnastics rings, shimmy up ropes, throw medicine balls around, and run while pushing weighted sleds. They choose these kinds of exercises because they require everyday motions, and perfecting those motions preps for all physical activity. The movements also enhance all 10 elements of fitness, including strength, agility, and speed. It's a well-rounded system, and one of the main reasons they subscribe to it. Another reason is its adaptability, allowing them to scale routines to the abilities of all ages and fitness levels.
