Strength training can be pretty intimidating. Walking into the weight room at the gym can be completely daunting, and it can be difficult to know just where to start. Not to mention the risk of injury is high if you aren’t taught to use proper technique. Circuit training offers a great alternative to traditional weights, and you can do this type of training just about anywhere. Consider using this quick 20 minute circuit training routine to build strength for surfing. The specifically designed squats benefit the odd off-center movements common to surfing, and the workout also targets the upper body and core strength crucial for powerful paddling.
