ProLaxTraining.com is always a helpful resource for getting an edge on the lacrosse field. Here is a technique called the “bodysaw,” which strengthens your core hardcore.
Core training for lacrosse needs to focus on stability, specifically anti-rotation, anti-flexion, and anti-extension. This exercise is a very advanced version of the plank and is a great anti-extension exercise. The key is to maintain the natural curve of your spine and to imagine you had a glass of water on your lower back that you didn’t want to spill. A strong, stable core will allow force to be transferred from your lower body to your upper body with no energy leaks, creating more power in your shots and checks. It will also create better posture and body control making you able to change directions faster.
