How to Properly Stretch Shoulders Before a Workout

The shoulder is a ball-and-socket joint that requires specific preparation before any demanding physical activity. Proper pre-workout preparation is necessary to enhance performance and protect the joint from strain or injury. A deliberate routine focuses on activating stabilizing muscles and increasing blood flow, ensuring the shoulder is ready to handle the force and range of motion required during training. This preparatory phase is distinct from post-workout recovery or general flexibility work.

Understanding Dynamic Warm-ups

The most effective way to prepare the shoulder is through a dynamic warm-up, which involves continuous, controlled movement rather than holding a fixed position. This movement-based approach increases the temperature of muscles and connective tissues, improving their pliability for the upcoming workout. Studies indicate that a dynamic warm-up can enhance subsequent performance metrics, such as power output.

This style of warm-up engages the nervous system, rehearsing the movement patterns used during the main exercise session. Unlike traditional static stretching, dynamic movements actively move the joints through a functional range of motion. This active engagement boosts blood circulation and prepares the body’s motor units to fire more efficiently.

Targeted Rotator Cuff Activation

The initial phase must focus on the four muscles of the rotator cuff: the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles stabilize the shoulder joint and control the rotation of the upper arm bone. Activation exercises should be performed slowly using very light resistance, such as a thin resistance band or a weight between one and five pounds.

Side-lying external rotations effectively target the infraspinatus and teres minor. To perform this, lie on your side with the working arm bent 90 degrees and the elbow resting on your torso, then slowly rotate the forearm upward against resistance. The reverse fly is another effective activation movement, performed bent-over with light dumbbells while focusing on squeezing the shoulder blades together.

Activating the scapular stabilizers, such as performing a shoulder blade squeeze or scapular retraction, is important to anchor the shoulder complex. This controlled, low-load work primes the smaller, deeper muscles to support the larger muscle groups during heavy lifting.

Full Range of Motion Mobility Drills

After activating the stabilizers, the next step involves larger, sweeping drills to increase mobility across the entire shoulder girdle, involving the deltoids, lats, and trapezius. These movements should gradually increase in range and speed without forcing the joint beyond a comfortable limit. Arm circles, performed in both forward and backward directions, are excellent for lubricating the joint capsule and increasing blood flow. Begin with small circles and slowly expand the diameter over ten to fifteen repetitions.

Arm swings are another foundational drill, performed by swinging the arms across the body horizontally and then front-to-back vertically. This encourages movement in multiple planes and helps to loosen the chest and back muscles that attach to the shoulder. Using a light dowel or resistance band for shoulder pass-throughs is beneficial, where the object is held with a wide grip and slowly moved from the front of the body, over the head, and toward the lower back. This movement addresses shoulder flexion and external rotation, ensuring the full range is available for the upcoming workout.

Actions to Avoid Before Training

Several common pre-workout practices can be counterproductive and compromise shoulder health. Prolonged static stretching, where a stretch is held for 30 seconds or more, should be avoided immediately before a workout, as it can temporarily reduce muscle strength and power output. The goal before training is to excite the nervous system, not to relax it.

Ballistic stretching, which involves bouncing or jerking movements, should also be avoided, as this can shock muscle fibers and connective tissue, increasing the risk of strain. Additionally, movements that cause direct impingement, such as performing upright rows or behind-the-neck presses, should be excluded from a warm-up routine. Avoid overloading the shoulder joint with excessively heavy weights during warm-up sets, instead prioritizing controlled movement with lighter loads to establish proper form.
