Ask Stew: When Should I Breathe During Exercises?

In weightlifting or calisthenics, an eccentric movement occurs when you lower the weight or lower your body, such as the downward portion of a pushup or the lowering of a dumbbell. A concentric movement occurs when you lift a weight or push your body up, such as pressing up from a squat or pushing yourself up during a pushup. Basically, eccentric means lengthening the muscle, and concentric means shortening it. Here is a question about the breathing process when doing the movements of weights or calisthenics:

Stew, Do you recommend exhaling while performing eccentric movements or concentric movements? Thanks, James.

James, typically, you want to “exhale on exertion,” and depending on the way you lift or do calisthenics, the exertion can be either the up or the down movement, or the concentric/eccentric part of the exercise. Most movements in weightlifting and calisthenics have the highest exertion during the concentric phase of the movement and the easier exertion during the eccentric phase. For instance, when doing a pullup by pulling your chin over a pullup bar, the harder movement is the upward movement, so the exhale is during that concentric movement, and the inhale is done in the easier downward/eccentric movement. However, in a similar movement with the pulldown machine, the harder movement is pulling the weight downward. It is still the concentric movement, so you exhale with that downward movement. The inhale is the upward movement of the weight. Think of it as bending the joint and shortening/flexing (contracting = concentric) the working muscles and then straightening the joint and lengthening/stretching (elongating = eccentric) the muscle, rather than just up or down movements.

Slow Eccentric Exhale (with Negatives)

At times, you exhale during the eccentric movements. Any slower downward movement of weights or calisthenics may require an exhale, especially if the movement is a 5-10 slow repetition. For instance, a common exercise is the negative pull-up to improve pull-ups. This means you get yourself over the bar with an assisted pull-up if needed, then slowly lower yourself down 5-10 seconds in the eccentric phase of the movement. Normally, you would exhale on the upward movement of the pull-up. But these are slow eccentric movements that require a slow exhale, as this is the most significant part of the exertion during the lift or movement.

Bracing Breath (Hold)

When lifting heavy weights off the floor, as in the deadlift or back squat, when the core is under constant load and pressure, you need to perform a bracing breath. The bracing breath works like this: As you prepare for the lift, take a deep inhale into your belly (diaphragmatic breathing), tighten your core by squeezing your ab muscles as if you were about to take a punch to the stomach, then lift. Keep breath held and core tight throughout the lift. Exhale when the bar returns to the floor. If you are doing another deadlift rep, repeat the deep inhale, brace and lift process. So, when lifting heavily off the floor or squatting, you inhale before the lift and exhale after the lift. Here is a Squat University video on bracing.
