You Can Avoid 90% of Joint Injuries in the Gym by Learning How to Train for Your Unique Anatomy — These Are the 5 Fixes Every Athlete Should Know

In his latest video, Jeremy Ethier breaks down the real reason so many lifters deal with joint pain — and it’s not just age or heavy weights.

It’s small training mistakes that add up over time. The good news? They’re easy to fix if you know what to look for.

Jeremy reveals five simple changes that can reduce pain, improve movement, and help you train harder for longer. Most people overlook these — don’t be one of them.

1. Stop Copying Others — Use Form That Matches Your Anatomy

There’s no such thing as a universal “perfect form.” What works for one person can be harmful for another, due to differences in bone length, joint mobility, and individual anatomy. Let’s start with the squat.

Someone with long femurs and tight ankles — like Max — will naturally lean forward during a squat. Trying to mimic someone with short femurs and great mobility — like Alex — would wreck Max’s lower back. The solution? Adjust your stance and squat style to fit your body instead of forcing a textbook position.

Try this self-test:

• Start with your feet shoulder-width apart, toes pointing forward. If it feels restrictive or painful, try the next stance.
• Widen your stance slightly and turn your toes out. Does squatting feel smoother? You may have found your sweet spot.
• Go even wider with more toe flare. Some people feel more stable this way, but be mindful — depth decreases as stance widens.

For forward-leaning squats, placing small plates under your heels can keep your balance and reduce stress on the lower back. This also shifts emphasis to the quads, making the movement more controlled.

Deadlifts are equally dependent on body structure. If you have shorter arms like Brendan, getting into a conventional setup without rounding your lower back could be nearly impossible. Instead, raise the bar with blocks or switch to sumo-style — both reduce lower back strain and optimize leverage.

Machine Adjustments Matter Too

Your setup on machines can make or break your joint health. For example:

• Leg extensions/leg curls: Ensure your knee lines up with the machine’s pivot point (usually marked with a sticker). Misalignment causes undue stress above and below the knee.
• Chest press/pec deck: Handles should be aligned with your nipple line. If too high or low, you’ll flare your elbows and overstress your shoulders.

2. Ignoring the Midback Is Hurting Your Shoulders

Shoulder stability isn’t just about the rotator cuff. Your traps and rhomboids — midback muscles — play a huge role in shoulder mechanics. Weakness here leads to poor scapular control and improper shoulder movement during presses or pulls.

The scapula isn’t anchored by a bone joint; it’s suspended in muscle. Think of it like a floating plank supported by tension cables. When one set of cables is loose — like your midback — the whole system wobbles, risking pain and injury.

The fix? Prioritize scapular activation during back training.

How to Properly Engage Your Back During Rows

1. Press shoulders down before pulling — skip the shrug.
2. Pull with your elbows, not your hands.
3. Pinch your shoulder blades together at the end of each rep — imagine holding a pencil between them.
4. Let your scapulae fully stretch at the bottom — don’t stay “locked.”

Even during vertical pulls like pull-downs or pull-ups, allow your shoulders to rise and roll at the top, then pull down with elbows while depressing your shoulders. This encourages full back engagement instead of relying solely on arms.

Bonus: Daily Prehab to bulletproof your shoulders

• ✔️ 3 sets of face pulls or prone arm circles after every upper body day
• ✔️ 10 wall slides every morning or during breaks from sitting

3. Fixed Bar Paths Are Wrecking Your Elbows and Wrists

Barbells may look symmetrical, but your body isn’t. Locking both hands onto a fixed bar path — especially during curls or pushdowns — ignores your natural joint angles, particularly at the elbow.

That slight outward angle of your forearm, called the “carrying angle,” is part of natural arm anatomy. When you force a straight bar curl, you’re twisting your arms into an unnatural position, increasing tension on ligaments and tendons. Over time, it causes wrist, elbow, and even shoulder pain.

Minimize Joint Stress by Varying Equipment

Every muscle group deserves at least one movement that allows for natural rotation. Try these substitutions:

• Chest & shoulders: Dumbbell bench press or Arnold press instead of barbell versions
• Back: Single-arm rows or lat pulldowns with free range of motion
• Biceps: Dumbbell or single-arm cable curls over straight bar curls
• Triceps: Cross-body cable pushdowns instead of bar pushdowns

Save those joints — and stay consistent in the gym, injury-free.

4. Progress Is Earned, Not Forced

Adding heavier weight every week sounds smart — until injuries creep in. Real progression happens when your body adapts and earns that extra resistance, not when you force it to keep up.

Skipping recovery, lifting despite poor sleep or low energy, or chasing PRs just for the numbers are all dangerous behaviors. One small compromise in form under fatigue can snowball into a major injury.

Better Ways to Measure Progress

• ✓ Add reps with the same weight
• ✓ Match last week’s reps with better form
• ✓ Use less effort to get the same results

All three options are valid and productive ways to progress — especially for intermediate or advanced lifters where gains come slower and injuries more quickly.

5. Same Movements Every Week? That’s a Slow-Burn Injury in the Making

Even if your form is perfect, repeating the same movement pattern for months on end creates overuse injuries. Any exercise, no matter how “joint-friendly,” can become a problem with too much volume over time.

Every 8–12 weeks, reassess your program:

• Are your elbows or knees starting to get sore on familiar movements?
• Has a nagging pain popped up in your wrist, back, or shoulder?

Rotate These for Joint Relief and Continued Gains

• Swap barbell bench for dumbbells or a machine chest press
• Change your pull-up grip (neutral, wide, underhand)
• Alternate between squats, leg presses, and Bulgarian split squats

This doesn’t mean avoiding hard work — it just means training smarter so you can keep showing up pain-free.

Final Thoughts: Listen to Your Body Before It Screams

Legendary bodybuilder Ronnie Coleman famously pushed past every sign his body gave him — and now, after multiple surgeries, he can barely walk. That’s not the trade-off you want.

A small whisper from your elbow or lower back is usually the first warning. Instead of telling your body to shut up, try listening. Lighten the load, improve your form, try new setups, or even sub in an entirely different exercise for a few months.

Your joints are asking for variety, personalization, and recovery. Give them that — and they’ll give you a lifetime of progress.
