Functional Exercise
What Is Functional Exercise?
Functional exercise is the foundation of modern physical therapy at VSI Physical Therapy, an award-winning physical therapy practice located in Reston, Virginia. Our movement-based physical therapy strengthens the patterns you use every day, such as squatting, lunging, hinging, pushing, pulling, and carrying, to reduce pain and get you back to life. This approach is also known as functional training, functional strength training, and activity-based rehabilitation because it rebuilds strength and control for real life tasks.
Exercise in all its forms is the absolute best tool when it comes to recovery. Functional exercise trains the body’s core movement patterns that are hard wired as we develop, from rolling and planking to squatting and standing. Training is organized around real life tasks so the strength and mobility you gain in the gym translate to walking the dog, lifting a suitcase, playing with your kids, and returning to your sport. We emphasize quality of motion first then add weight and speed as you improve. Many people think of this as functional fitness or everyday movement training because it focuses on how you live and move.
Functional Exercise Benefits
Functional exercise is an effective option for patients who want pain relief, better movement, and lasting results from movement-based physical therapy. Exercise and movement are skills, and all skills require practice to see results. Also called functional training, functional strength training, and activity-based rehabilitation, this approach restores the patterns you use every day and supports long-term health.
