When you think about workouts, your mind might go straight to biceps, abs, or legs. But what about your fingers and wrists? Whether you’re a manual therapist, a musician, or someone who spends hours typing, your hands deserve just as much attention as the rest of your body. Today, we’re diving into exercises specifically designed to enhance the flexibility and strength of your fingers and wrists, addressing common issues like trigger finger and epicondylitis.

The Importance of Shoulder Internal Rotation and Extension

Internal rotation and extension of the shoulder are not just isolated movements; they are interdependent and frequently trained together. These motions are vital for various activities, including golfing, weightlifting, and even daily tasks like reaching or lifting. In golf, proper shoulder internal rotation and extension are key to achieving a full and effective swing. Similarly, in the gym, exercises like the bench press rely heavily on these shoulder motions.

Training Shoulder Internal Rotation and Extension

At Twin Cities Movement, we emphasize the importance of training both internal rotation and extension through PAILs (Progressive Angular Isometric Loading) and RAILs (Regressive Angular Isometric Loading). These techniques are highly effective in increasing range of motion and improving joint health. Let’s dive into a practical approach to enhancing shoulder internal rotation using PAILs and RAILs.

Step-by-Step Guide to Improving Shoulder Internal Rotation

1. Side-Lying Position for Shoulder Internal Rotation:
• Begin by lying on your side with a block or pillow under your head for comfort.
• Trap your shoulder blade down onto the floor, pulling it slightly to ensure it stays in place.
• Use your opposite hand to assist in internally rotating your shoulder until you reach your stopping point, keeping your elbow high and stationary.
2. Initial Passive Stretching:
• For two minutes, hold this position with the weight of your assisting hand on your wrist, not forcing the movement but allowing a gentle stretch.
3. PAILs Contraction:
• After the passive stretch, start pushing your wrist into your assisting hand as hard as you can for 4 to 8 seconds, creating an isometric contraction without actual movement.
4. RAILs Contraction:
• Following the PAILs contraction, try to pull your wrist towards the floor, again holding this contraction for 4 to 8 seconds, and then relax.
5. Repeat the Process:
• After another minute of passive stretching, repeat the PAILs and RAILs contractions. This process helps in gradually increasing your range of motion over time.

Improving Shoulder Extension

Just as important as internal rotation is shoulder extension, another crucial component for a fluid golf swing. Here’s a step-by-step guide to improving shoulder extension using PAILs and RAILs.

1. Seated Position for Shoulder Extension:
• Sit on the floor with your knees bent and feet flat. Place your hands behind you with fingers pointing backward.
• Unlock your elbows slightly to minimize bicep involvement, focusing the stretch on the front of your shoulders.
2. Initial Passive Stretching:
• Slide your butt towards your feet until you feel a stretch in your shoulders. Hold this position for two minutes.
3. PAILs Contraction:
• Push your hands into the floor as if trying to sweep them under you, creating an isometric contraction for 4 to 8 seconds.
4. RAILs Contraction:
• Attempt to lift your hands off the floor, holding the contraction for 4 to 8 seconds, then relax.
5. Repeat the Process:
• Repeat the PAILs and RAILs contractions after another minute of passive stretching to further increase your range of motion.

Integrating Internal Rotation and Extension: Controlled Articular Rotations (CARs)

To finish, we move to Controlled Articular Rotations (CARs) for your fingers. This exercise ensures that the new strength and flexibility are functional and can be applied to everyday movements.

1. Wide Hands: Start with your fingers spread as wide as possible.
2. Isolated Movement: Move each finger individually through its full range of motion. For example, lift your thumb slightly off the floor and move it in and out, aiming for three to five repetitions per finger.
3. Minimal Movement: The key is to keep the movements small and controlled, just barely lifting the fingers off the floor. This isolates the extensor muscles and prevents compensation from other parts of the hand.

Repeat: Perform this exercise for each finger, paying attention to any that struggle more than others. You’ll likely notice differences in control and strength between fingers—this is normal and will improve with practice.

Why These Exercises Matter

Regularly performing these exercises can help alleviate and prevent conditions like trigger finger and epicondylitis. By focusing on both flexibility and strength, you’re not just making your hands more resilient; you’re making them antifragile. This means they’ll not only withstand stress but also get stronger from it.  

Conclusion

At Twin Cities Movement, we understand that every individual’s needs are unique, and our approach is tailored to meet those specific needs. By focusing on shoulder internal rotation and extension through targeted exercises like PAILs and RAILs, you can significantly improve your shoulder health and performance.

Whether you’re aiming to perfect your golf swing, lift more effectively in the gym, or simply move better in daily life, these techniques are invaluable tools on your journey to better shoulder mobility and function.Remember, consistency is key. Regular practice of these exercises will yield the best results, helping you stay active, independent, and capable for years to come. So, get started today and unlock the full potential of your shoulders!
