If you’ve ever caught yourself slacking on your form and simply powering through a tough sequence just to get to the end, you are not alone. Keeping proper form is one of the most important aspects of Pilates, but maintaining that level of deep, focused precision can be challenging as fatigue sets in across a 50-minute class.
When we get tired, our bodies look for shortcuts. These alignment shifts can affect the efficiency and effectiveness of your workout. To help you get more out of your next class, we’ll break down three common alignment shifts that happen when you get tired, plus quick tips to fix them right away.
Arching the Lower Back
When it happens: This often shows up when your legs are extended away from your core. The further your feet travel from this anchor point, the heavier they feel, requiring your deep core to work much harder to keep your lower back from arching off the carriage.
Common exercises: A few common exercises where this can occur include The Hundred, leg lowers & lifts, and double- and single-leg extensions.
Quick fix: Imagine pulling your front ribs down and in, like you’re wearing a fitted corset. Keep your pelvis heavy and anchored. If your lower back starts to lift or arch, don’t lower your legs as much. Smaller, controlled movements are often more effective. Some exercises may benefit from a gently imprinted spine to reduce strain on the lower back and support deeper core engagement. This can help you better activate the abdominal muscles while avoiding unnecessary tension in the back.
Lifting the Shoulders (Neck Tension)
When it happens: This commonly occurs when tension builds in the neck and shoulders during challenging movements, especially when the arms are under load, or the core begins to fatigue. Instead of staying supported through the upper back and core, the shoulders begin to creep toward the ears, creating unnecessary tension in the neck and upper body.
Common exercises: A few common exercises where we most often see this include the mid-back series in straps, chest expansion, or a front-rowing series.
Quick fix: Imagine sliding your shoulder blades down and wide across your rib cage while keeping space between your shoulders and ears. Maintain stability through the shoulder girdle without gripping or squeezing the shoulder blades together. Keep the chest open and collarbones wide, allowing the scapulae to move naturally while staying supported. Focus on initiating movement from the core and upper back rather than the neck and shoulders.
Powering Through a Movement vs Moving with Control
When it happens: This often occurs when momentum takes over, and the movement is “powered through” rather than controlled. It often shows up when fatigue sets in or when trying to increase speed or intensity. This can cause the breath to become shallow and the core to disengage.
Common exercises: A few common exercises where this can occur include lunge sequences, bear, upper body sequences (i.e., serve the platter, hug a tree, the offering), and feet in straps.
Quick fix: Slow the movement down and match it with your breath. Inhale to prepare and exhale to initiate the effort, drawing the ribs gently down and in as you move. Think of controlling each phase of the exercise rather than rushing through it. If you start to lose form or breath becomes strained, reduce the range of motion or intensity. Focus on steady, intentional movement, with the breath supporting the core rather than driving momentum.
Next time you’re in the studio, try slowing down, checking your alignment, and focusing on precision instead of speed. Your body will thank you.
