As the summer weather warms up across Somerset, many of us are looking for ways to stay active while keeping cool. Whether you are clocking up regular lengths in the indoor pool, dipping into local lakes, or enjoying a wild swim along our beautiful Weston-super-Mare coastline, swimming is an exceptional way to build cardiovascular endurance and overall strength.
Because the water supports your body weight, swimming is widely celebrated as the ultimate “zero-impact” exercise. However, from an osteopathic perspective, moving through water introduces a highly specific physical challenge. Water provides significant fluid resistance, effectively turning every single stroke into a repetitive strength exercise for your upper body and spine.
If your structural framework isn’t moving with total adaptability, what feels like a gentle dip can quickly lead to repetitive strain. Today, we are breaking down why the water can sometimes trigger aches in your shoulders and lower back, and how to condition your body to swim smoothly and pain-free.
The Fluid Resistance Strain: Moving Against the Water
When you swim, your arms and spine perform the exact same rotational loops hundreds of times per session. While there is no hard ground to impact, your internal mechanics must be fully adaptable to handle the constant resistance of the water. If certain joints are restricted, two common mechanical bottlenecks tend to develop:
1. The Front-Shoulder Pinch (Swimmer’s Impingement)
To pull yourself through the water effectively during freestyle or front crawl, your arm has to rotate high overhead. However, if your chest and shoulders are already tight from hours spent leaning over a workbench, a kitchen unit, or a desk during the working week, that overhead space becomes restricted. Over a few dozen lengths, the tendons at the front of the shoulder get repeatedly pinched against the bone, leading to a hot, nagging ache when you reach overhead.
2. The Breaststroke Back-Nip
Breaststroke is a favorite for leisurely summer swims, but it requires you to keep your head up to breathe. If your mid-back (thoracic spine) is stiff and unyielding, you cannot lift your chest comfortably out of the water. Instead, your body forces your lower back to sharply arch to keep your mouth clear of the water line. After a swim, this leaves the joints of your lower back feeling compressed, tight, and nipped.
Three Structural Resets for the Water
To ensure your joints can freely adapt to the fluid resistance of the water, try weaving these simple conditioning habits into your swimming routine:
- The Mid-Back Extension (Before Your Swim): Before heading to the pool or beach, kneel on the floor and place your elbows on the edge of a chair or sofa. Gently lower your chest toward the floor, letting your head drop between your arms. This opens up your thoracic spine, giving your shoulders the mechanical freedom they need to rotate overhead without pinching.
- The “Low Head” Reset (For Breaststroke): If you prefer breaststroke, practice letting your face dip naturally into the water between strokes rather than keeping your neck cranked back the entire time. This simple change allows your spine to lengthen and prevents your lower back from taking a constant hammering.
- The Post-Swim Windmill (After Your Swim): After getting dried, stand tall and perform 5 slow, backward arm circles on each side. Keep your movements deliberate and wide, focusing on opening the front of your chest to reverse the tight, forward-pulling mechanics of swimming strokes.
How We Help at Pure Health Osteopath Clinic
If your shoulders pinch after a few lengths, or your lower back feels locked up the morning after a swim, it is a sign that your structural framework is lacking the adaptability needed for the water. If your ribs or mid-back are restricted, your shoulders and lower back are forced to overwork to compensate for that lack of movement.
As a local Weston-super-Mare osteopath, my goal is to identify and release these hidden areas of mechanical stiffness. By restoring balanced mobility to your thoracic spine and improving the fluid movement of your shoulder blades, we take the extra pressure off those overworked tendons and lower back joints. Our goal is to ensure your body cuts through the water smoothly, so you can enjoy your summer swims completely pain-free.
Your body should move through the water with ease. Whether you are a casual dip-taker or a dedicated open-water swimmer, let’s make sure your joints are moving beautifully so you can make the most of the season.
