Common Exercise Form Mistakes and How to Fix Them

Strong Foundations: Why Movement Quality Matters

In fitness, how you move is just as important as how often you move. When your technique slips or you push intensity over control, you’re not just limiting your progress—you’re increasing your risk of injury.

Injury Prevention: Move Wrong, and You’ll Pay for It

Poor movement patterns can sideline your training in an instant. Over time, small mistakes—like improper form during a lift or repetitive overuse—compound into major problems.

  • Incorrect mechanics lead to joint strain and muscle imbalances
  • Ignoring form to “get it done” can result in long-term setbacks
  • Recovery from injury often takes more time than building the habit right the first time

Movement Quality Drives Results

Efficient, clean movement allows you to target the right muscles and train with purpose. It’s not about doing more—it’s about doing it right.

  • Precision in reps leads to better muscle engagement
  • Better engagement = stronger, more sustainable progress
  • Quality reps reduce unnecessary fatigue and improve recovery

Consistency Over Intensity

The best athletes aren’t always the ones who push hardest—they’re the ones who show up consistently, while minimizing injury risk.

  • Train smart so you can train often
  • Sustainable progress comes from small, well-executed steps over time
  • Long-term results depend on long-term participation

Smart movement isn’t just about avoiding injuries—it’s the foundation of real, lasting progress.

Squat Mistake: Knee Collapse

When your knees cave in during a squat—often referred to as knee valgus—it can cause more damage than you think. This common mistake not only reduces the efficiency of your movement, but it can also put significant strain on your knees and reduce your overall power output.

What’s Causing It?

Often, this issue stems from:

  • Weak glute muscles, especially the glute medius
  • Poor foot positioning, such as feet turned too far in or lacking arch support
  • Lack of body awareness during the movement

Why It Matters

Letting your knees collapse affects more than just your form. The effects include:

  • Knee strain and instability
  • Reduced power transfer through the hips and legs
  • Higher risk of injury over time, especially under heavier loads

How to Fix It

Fortunately, this issue is fixable with focused adjustments:

  • Drive your knees outward as you squat—think about tracking them over your toes
  • Adjust your stance to find a position where your knees can stay aligned comfortably
  • Strengthen supporting muscles, including glutes, hamstrings, and external rotators
  • Incorporate resistance bands in warm-ups to reinforce proper movement paths

That classic hunched position during a lift? It’s a trap. You’ll spot it when the spine curves and the bar—or any weight—starts dragging you forward. Common in deadlifts, rows, and even squats when form slips. It’s not just ugly. It’s dangerous.

When you round your back and drop your chest, you load your spine under pressure it’s not built for. Think of it like bending a straw, then trying to crush it from the top. Doesn’t end well. Spinal loading in a bad position cranks up the risk of disc injury, strain, and long-term damage.

Here’s the fix: pull your shoulder blades back and down, engage your lats like you’re trying to pinch something under your arms. Hinge from the hips, not from the waist. That sets the spine into a neutral, load-bearing shape. Everything stacks; tension works for you, not against you.

Use mirrors. Film yourself. Don’t guess—see what your body’s actually doing. Awareness fixes form, and proper form saves your back.

When your bench press form starts to break down, it’s usually not a mystery. The two main culprits: too much load on the bar and not enough control in your shoulders. Trying to chase PRs without setting a solid foundation won’t just plateau your progress—it’ll put your joints at risk.

The biggest red flag? Shoulder impingement. That grinding, pinching discomfort shows up when your elbows flare out too wide and your shoulders drift forward. It’s also a recipe for inefficient pressing. You waste power, lose tension in your lats, and make the lift harder than it needs to be.

The fix is simple, not easy. Tuck your elbows in to about 45 degrees from your torso—not too close, not flared. Lock your shoulder blades down and back before the bar even moves. This stabilizes the joint, protects soft tissue, and channels more force into the press.

If positioning feels off, grab a resistance band. Wrap it across your back and hold each end in your hands while benching. It’ll cue you to pull your arms in and activate key muscles. Smart cueing beats mindless sets. Clean up your setup, clean up your press.

Plank Form Mistakes to Avoid

Planks may look simple, but poor form can make this foundational move ineffective—or even harmful. Getting it right matters, especially if you’re serious about building core strength and preventing injury.

What Goes Wrong

It’s easy to overlook subtle posture issues when you’re focusing on holding a plank. Common mistakes include:

  • Sagging hips: This drops your core engagement and strains your spine.
  • Arched lower back: A sign that the core isn’t properly activated, leading to pressure on the lumbar region.

The Risks

When done incorrectly, planks can lead to more harm than good:

  • Lower back strain from poor alignment
  • Wasted effort—you’re holding a position that doesn’t effectively train your core

How to Fix It

Great form starts with body awareness and subtle muscle activation. Here’s how to set yourself up for success:

  • Tighten your glutes to support your pelvis
  • Brace your core (imagine preparing for a light cough)
  • Align your shoulders directly over your elbows and stack your hips in line with both

Pro Tip: Quality Over Duration

Don’t chase time. Start with shorter plank holds—20 to 30 seconds—and increase as your form improves. A rock-solid 30-second plank beats a shaky 2-minute hold every time.

  • Prioritize form above all
  • Use a mirror or record yourself to check alignment

You’ve seen it—and maybe you’ve done it. That full-body swing during curls. The knees dip, the back arches, and suddenly it’s not a curl, it’s a deadlift in disguise. The problem? Your biceps aren’t doing most of the work. Momentum is.

When you swing through a curl, the tension shifts away from the muscle you’re supposed to be targeting. That cheats growth, and it’s easy to stall out without realizing why.

Fix it by lowering the weight. You should be able to control both the lift and the descent. Slow the rep down. Lock your elbows by your sides and move only your forearms. Strict form over bragging rights, every time.

You’re not trying to impress the mirror—you’re trying to build muscle that lasts.

Spot-checking your form isn’t optional—it’s survival. Video yourself regularly. You’ll catch things you thought you fixed weeks ago. Awkward knees, unstable shoulders, rounded backs—they sneak in when you’re not paying attention.

Start light. Earn your way to heavier loads. Most injuries in gyms don’t come from bad programming—they come from egos writing checks your body can’t cash. Master the movement with lower weights before ramping up. Progress stacks fast when you don’t have to keep fixing bruised joints.

On that note, ditch the ego lifts. Lifting for views or pride instead of stability and control is a dead-end street. Strong doesn’t always look loud. Your joints will thank you in five years.

Lastly, even the self-taught need a second set of eyes. Hire a coach or trainer at least once to gut-check your patterns. One session can expose months of drift. Think of it as preventative maintenance before the engine knocks.

Train smart. Stay in the game.

Form isn’t optional—it’s foundational. In 2024, vloggers who ignore structure are dead in the water. With algorithms valuing retention more than clicks, how you package your content matters just as much as what you say. Open strong, deliver with precision, and close with impact.

You don’t need to reinvent the wheel every time. Find a format that works—maybe it’s a quick cold open followed by a topical breakdown, or a recurring three-act structure—and get good at it. Revisit it often. Tweak based on data, not vibes. Iteration is your best weapon.

The difference between a forgettable vlog and one that builds a loyal following? It’s often not the gear or even the topic—it’s the form. Lock that in, and the rest follows.
