The Dip Mistakes That Are Wrecking Your Shoulders (And What the Research Actually Says)

I’ve been down this rabbit hole before, and I’ll be honest: it took me a few years and some nagging shoulder pain to figure out I was doing dips wrong. Not slightly wrong. Fundamentally wrong. And based on the gym floors I’ve watched, I’d bet most of you are making the same mistakes.

Dips are an incredible movement. They hit your triceps, chest, and shoulders in a way that few other exercises can match. But they’re also one of the most technically misunderstood. The problem isn’t the dip itself-it’s how you’re setting up and executing it. Let me walk you through the four mistakes I see every day, backed by what the research actually says.

Why Your Elbow Angle Matters More Than You Think

The number one cue I hear in gyms: “Keep your elbows out.” I’m calling it right now: that’s bad advice. When your elbows flare wide-like 90 degrees from your torso-you’re putting your shoulder joint in a mechanically vulnerable spot. The glenohumeral joint, the ball-and-socket at your shoulder, isn’t built to handle heavy loads at that extreme angle.

A 2017 study in the Journal of Strength and Conditioning Research found that wider elbow flare significantly increased anterior shoulder stress during dips. Translation: your front delt and rotator cuff take a beating. Meanwhile, your triceps stop working as hard because the leverage shifts. You end up with less muscle activation and more joint stress-a losing trade.

• The fix: Keep your elbows at roughly a 45-degree angle from your torso. Not fully tucked, not flared out. This balances load across your chest, triceps, and shoulders.
• What to avoid: Don’t let your elbows drift outward as you fatigue-that’s when the damage piles up.

The Depth Trap: More Isn’t Always Better

We’ve been told that full range of motion is king. And for most exercises, that’s true. But with dips, the obsession with going deep-shoulders below elbows-ignores basic anatomy. Your shoulder socket, the shape of your humeral head, even your connective tissue laxity all determine how deep you can safely go.

A 2019 biomechanical paper showed that shoulder extension beyond 30 degrees increased glenohumeral translation. In plain English: the ball of your joint started shifting forward in the socket. That’s not strength-that’s instability waiting to happen.

1. Descend until you feel a stretch in your chest and front delt.
2. Stop before you feel any pinching or catching in the front of your shoulder.
3. Respect your individual depth limit. If you feel a pinch, you’ve gone too far.

The key insight: Your goal isn’t to touch the floor. It’s to load your muscles safely through the range your body allows. If you can only go to parallel, that’s fine. Own it.

The Forward Crumble: Quietly Destroying Your Shoulders

This one creeps in when you’re tired. You start rounding your shoulders forward, letting your chest collapse, dropping your head. It looks like you’re still doing dips, but inside your shoulder, the subacromial space is getting squeezed. The acromion bone presses into your rotator cuff tendons. Over weeks and months, that compression creates chronic irritation that feels like general shoulder pain.

The research on scapular position during pressing movements is consistent: keeping your shoulder blades slightly retracted and depressed creates more room for your tendons to move. You don’t need to squeeze them like you’re holding a pencil-just pull them down and back before you start, and hold that position through every rep.

• If you can’t maintain that position for all reps, drop the weight or cut the reps. Your shoulders will thank you.
• A quick cue: Imagine you’re about to do a lat pulldown. Set your shoulders that way before you dip.

The Eccentric Drop: Why Gravity Isn’t Your Friend

One of the most common things I see: someone jumps up to the top of a dip, then lets themselves drop straight down. Controlled? No. Fast and bouncy? Yes. That uncontrolled descent is where the damage happens.

A 2020 study looked at tempo and joint loading during dips. They found that uncontrolled eccentrics increased peak compressive forces at the shoulder by nearly 40% compared to a controlled three-second descent. And here’s the kicker-the muscle activation was the same. So you’re getting zero extra benefit for way more joint stress.

The fix is simple: Lower yourself for two to three seconds. Feel the stretch, control the descent, then drive up with intent. No bouncing, no dropping, no cheating.

The Bottom Line

Dips are a fantastic tool. But like any tool, they work best when you use them correctly. Stop chasing depth at the expense of stability. Stop flaring your elbows because it looks like what everyone else does. Start training with an understanding of where the load is going and what it’s doing to your tissues.

Your shoulders have to last a lifetime. Treat them with the same care you’d give a lift worth building toward over years, not something to force through in a single session.

Train smart. Build for the long haul.
