In the extreme scheme of things, the rewards outweigh the risks, even though the stakes are high. We all have a uniqueness in the way our bodies move. That's why it's easier to identify a surfer on a wave by his style rather than the color of his board or suit. By identifying our major muscle groups being recruited for surfing, we then may begin the process to improve muscular imbalances that occur in sport specific activities such as surfing. Identifying the prime movers throughout the act of catching and riding waves is essential in understanding the relationship of other muscle groups of lesser use.
Abdominal strength is extremely important for surfers to successfully perform maneuvers.
The prime movers being recruited for the trunk area of course are the abdominal and erector spinae. Strong abs and erectors will increase stabilization and also help prevent injury of the spine, which of course happens to be the most common among surfers. Exercises for abdominal would be spinal flexion or crunches. The most obvious group of muscles involved in surfing are within the upper body. To propel ourselves through the water on a surfboard requires a combination of muscle groups working in harmony to maintain the path of motion the arms require for this task.
