Active Shoulders: The Foundation of Safe and Strong Movement in CrossFit

If you’ve been doing CrossFit for a while, you’ve probably heard your coach say things like, “push up into the bar,” “shoulders active,” or “don’t let your shoulders dump forward.” But what does all of this actually mean, and why does it matter so much?

Active shoulders are one of the eight common movement themes taught in CrossFit’s Level 2 training, and for good reason. This concept applies to almost every upper-body movement you do. Understanding it can dramatically improve both your safety and performance.

If you’d rather listen to this conversation, you can do that here.

What Are Active Shoulders?

An active shoulder position means positioning your shoulder to maximize range of motion, strength, and joint stability. Essentially, you’re applying force with your shoulder opposite to the load, or resisting yielding to whatever force is acting on you.

Think about a barbell press: the barbell is pushing down on you with gravity, so you’re pushing up into the load while also externally rotating your shoulders. You’re not passively holding the weight; you’re actively engaged.

Why It Matters: Safety First

Your shoulder is often described as a ball-and-socket joint, but anatomically, it’s more like a golf ball sitting on a tee. There’s potential for a lot of movement, which is great for mobility, but when you’re supporting a load, you want to be locked in and stable.

When you externally rotate and push up with an active shoulder against a load overhead, you create that stable position. Without it, any downward pressure on your shoulder can cause it to slip and slide through the joint, and we don’t know how or where it might move. This instability isn’t just inefficient; it’s dangerous.

By maintaining an active shoulder position, you:

• Reduce the risk of impingement
• Keep your shoulder in its strongest, most stable position
• Prevent the joint from moving unpredictably under load
• Build confidence when supporting weight overhead

The Performance Advantage

Beyond safety, active shoulders put your muscles in the strongest, most efficient position. If your shoulder is at an angle when you’re supporting weight overhead, you’re losing power and wasting energy. A locked-in, active position allows for better force transfer and more efficient movement.

Active Shoulders Across Different Movements

Here’s where it gets interesting: active shoulders look different depending on the movement you’re doing. It’s not a one-size-fits-all cue.

Overhead Press

Push up into the bar while externally rotating your shoulders. Think about creating that stable, locked-in position at the top of the movement.

Ring Dips and Support Positions

Your shoulders push down and in toward the rings. You’ll also rotate your thumbs forward to optimize shoulder position. The direction changes, but the principle remains the same: you’re actively engaging against the load.

Olympic Lifts

Active shoulders play a role in two ways:

1. Overhead (like in the jerk): Same as the overhead press position
2. During the pull: Maintain good posture and don’t let the weight pull your shoulders forward. Keep your shoulder girdle engaged — think about all the muscles around your shoulder and upper back working together to maintain rigidity. This helps transfer force from the ground through your midline, through your shoulders, and into the bar.

Push-Ups and Planks

This is where many people (myself included) got it wrong for years. In the support position of a plank or at the top of a push-up, your shoulders should actually be pushing forward and down into the ground. Your shoulder blades protract (separate) at the top and retract (come together) as you descend.

Throughout the movement, generate torque by imagining you are screwing your hands into the ground. This builds external rotation and maintains active shoulders as you move through the full range of motion.

Hanging Movements

Pull your shoulders away from your ears slightly. Avoid the “shrug up” position and instead create that active engagement even when hanging.

Bench Press

While you’re moving through the range of motion, your shoulder position should remain relatively stable and locked in. The shoulder itself doesn’t move much; it’s locked into that strong position while your arms bend and straighten.

A Framework for Better Movement

Understanding active shoulders gives you a framework for analyzing any upper-body movement you encounter. Instead of just going through the motions, you can ask yourself:

• Am I in the strongest, most stable position for this movement?
• Am I applying force opposite to the load?
• Is my shoulder locked in, or am I passively yielding to the weight?

For example, many people can do push-ups easily, but that doesn’t mean they’re doing them correctly. If you’re dumping into your shoulders and losing that stable position, you’re not only hampering your performance but also putting unnecessary stress on your tissues and potentially setting yourself up for injury.

Putting It Into Practice

The next time you’re in the gym:

• Overhead movements: Push up into the bar, externally rotate, lock it in
• Ring work: Push down into the rings, thumbs forward
• Pulling movements: Keep your shoulders back, maintain good posture, don’t let the weight pull you forward
• Push-ups/planks: Push forward and down, create torque, feel your shoulder blades moving properly
• Hanging: Pull shoulders slightly away from ears, stay engaged

The Bottom Line

Active shoulders apply to virtually every upper-body movement in CrossFit. Whether you’re pressing, pulling, supporting your bodyweight, or hanging, understanding how to position your shoulders properly will make you safer, stronger, and more efficient.

The shoulder girdle — including your scapula, rotator cuff muscles, and all the musculature around your shoulder and upper back — works together to create these strong positions. When you train with active shoulders consistently, you’re building not just strength, but also the neuromuscular patterns that keep you safe under load.
