Exercises to Avoid or Modify: Common Problematic Movements and Better Alternatives

Not all exercises are created equal—and some popular movements carry more risk than benefit for many people. This guide examines commonly problematic exercises and provides safer alternatives that achieve the same goals.

Important Note: "Avoid" doesn't mean "dangerous for everyone." It means these exercises frequently cause problems and have better alternatives available. Individual anatomy, injury history, and training goals matter.

Behind-the-Neck Press

The Problem

Pressing a barbell or machine behind your neck places the shoulder in extreme external rotation under load—a position that stresses the rotator cuff, labrum, and joint capsule.

Risk Factors:

• Shoulder impingement
• Rotator cuff strain
• Labral damage
• Limited shoulder mobility makes it worse
• Most people lack the mobility to do this safely

Better Alternatives

• Standard overhead press (barbell in front)
• Dumbbell shoulder press (neutral or angled grip)
• Landmine press (angled path, shoulder-friendly)
• Arnold press (rotational movement, natural path)

When It Might Be Okay

Olympic weightlifters and some athletes may benefit, but only with excellent shoulder mobility and proper coaching. For general fitness—skip it.

Behind-the-Neck Lat Pulldown

The Problem

Same issues as behind-neck press: extreme shoulder position under load, plus forward head posture during the movement.

Risk Factors:

• Shoulder impingement
• Rotator cuff stress
• Cervical spine strain (neck)
• Most people compensate with poor form

Better Alternatives

• Lat pulldown to chest (standard form)
• Neutral grip pulldown (palms facing each other)
• Pull-ups/chin-ups (to chest, not behind neck)
• Cable rows (horizontal pulling)

---

Upright Rows (Narrow Grip)

The Problem

Pulling weight up with elbows high and hands close together internally rotates the shoulder under load—a recipe for impingement.

Risk Factors:

• Shoulder impingement (very common)
• Rotator cuff irritation
• Narrower grip = higher risk
• Heavy weight makes it worse

Better Alternatives

• Wide-grip upright row (hands outside shoulders, less impingement)
• Face pulls (external rotation, shoulder-healthy)
• Lateral raises (isolated lateral delt work)
• Cable high pull (modified path)
• Dumbbell high pull (allows natural arm path)

Modification If You Must Do Them

• Hands at shoulder width or wider
• Don't pull higher than chest level
• Keep weight moderate
• Stop if any shoulder discomfort

Leg Press with Excessive Depth

The Problem

Going too deep on the leg press causes the pelvis to tuck under (posterior tilt), loading the lumbar spine in a vulnerable flexed position.

Risk Factors:

• Lower back injury
• Disc issues
• Hip impingement
• The machine doesn't allow natural movement

Safe Approach

• Stop descent when pelvis starts to tuck
• Keep lower back pressed into pad
• Depth varies by individual hip anatomy
• Some people can safely go deep; many cannot

Better for Deep Squatting

• Goblet squat (self-limiting, natural depth)
• Bodyweight squat (learn proper depth)
• Front squat (self-limiting due to position)

---

Seated Leg Extension (Heavy, Full Range)

The Problem

Open-chain knee extension with heavy weight at full range creates significant shear force on the knee joint and stress on the ACL.

Risk Factors:

• Patellar tendinitis
• Patellofemoral pain
• ACL stress (especially in final degrees of extension)
• Often done with ego-driven weight

Safer Approaches

• Lighter weight, higher reps (less joint stress)
• Limited range of motion (avoid full lockout)
• Terminal knee extensions (with band, smaller ROM)
• Spanish squat (quad loading in closed chain)
• Leg press (closed chain, quad emphasis with foot placement)

When It May Be Appropriate

• Rehab settings (controlled, specific ROM)
• Bodybuilding (moderate weight, controlled tempo)
• Not the primary quad exercise

---

Smith Machine Squats (Feet Forward)

The Problem

The fixed bar path forces unnatural movement. Placing feet forward (common setup) creates shear force on the knees and removes glute/hamstring involvement.

Risk Factors:

• Knee stress from unnatural position
• Lower back strain
• Doesn't teach proper squat mechanics
• False sense of stability

Better Alternatives

• Barbell back squat (free bar path)
• Goblet squat (self-limiting, teaches pattern)
• Hack squat machine (similar stability, better path)
• Leg press (if stability is the concern)

If Using Smith Machine

• Keep feet under the bar, not forward
• Use for specific purposes (overload, safety)
• Don't make it your primary squat

---

Crunches and Sit-Ups (High Volume)

The Problem

Repeated spinal flexion under load stresses the lumbar discs. High-volume crunching can contribute to disc issues over time.

Risk Factors:

• Disc herniation (especially with twisting)
• Neck strain (pulling on head)
• Hip flexor dominance
• Doesn't effectively train core function

Better Core Exercises

• Plank variations (anti-extension)
• Dead bugs (anti-extension with movement)
• Pallof press (anti-rotation)
• Bird dogs (anti-rotation, stability)
• Ab wheel rollouts (anti-extension, challenging)
• Hanging leg raises (flexion without spinal compression)

When Crunches Are Acceptable

• Occasional, moderate volume
• Healthy spine with no history of issues
• As part of varied core training
• Not the foundation of core work

Good Mornings with Excessive Weight

The Problem

While good mornings can be effective, heavy loading places significant stress on the lower back in a mechanically disadvantaged position.

Risk Factors:

• Lower back injury
• Disc problems
• Often done with poor form
• Easy to round the back

Safer Alternatives

• Romanian deadlift (load in front, easier to maintain position)
• Hip hinge with light weight (pattern learning)
• Back extensions (supported, adjustable ROM)
• Cable pull-through (constant tension, spine-friendly)

If Doing Good Mornings

• Keep weight moderate
• Master hip hinge pattern first
• Maintain flat back throughout
• Use as accessory, not primary movement

Kipping Pull-Ups (Without Foundation)

The Problem

Kipping creates momentum that stresses the shoulders, especially at the bottom of the movement when the body swings forward.

Risk Factors:

• Shoulder injury (labrum, rotator cuff)
• Requires existing strength base
• Often done to compensate for weakness
• High repetitions increase injury risk

Better Progression

1. Build strict pull-up strength first (5-10 strict)
2. Develop shoulder stability (especially overhead)
3. Learn proper kipping technique (from qualified coach)
4. Don't kip to compensate for weakness

For General Fitness

Strict pull-ups and chin-ups provide all the benefits without the shoulder risk.

Barbell Skull Crushers (Heavy)

The Problem

The bottom position places the elbow in extreme flexion under load, stressing the triceps tendon and elbow joint.

Risk Factors:

• Elbow tendinitis
• Triceps strain
• Joint stress increases with weight
• Fixed bar path doesn't allow natural movement

Better Alternatives

• Dumbbell skull crushers (natural wrist/elbow path)
• Cable overhead extension (constant tension, adjustable angle)
• Close-grip bench press (compound, less elbow stress)
• Tricep pushdowns (easier on elbows)
• Dips (compound, natural movement)

If Doing Skull Crushers

• Use moderate weight
• Lower to forehead or above, not behind head
• Consider dumbbells over barbell
• Stop if elbow discomfort

---

Weighted Side Bends

The Problem

Lateral spinal flexion under load stresses the spine in a direction it's not optimally designed for. Often done incorrectly with momentum.

Risk Factors:

• Spinal stress
• Doesn't effectively target obliques
• Can thicken the waist (muscle growth)
• Better alternatives exist

Better Oblique Exercises

• Pallof press (anti-rotation)
• Side plank variations (anti-lateral flexion)
• Suitcase carry (anti-lateral flexion, functional)
• Cable woodchop (rotational, controlled)
• Hanging oblique raises (if advanced)

---

Jumping Straight Down (Depth Jumps Without Progression)

The Problem

Advanced plyometrics like depth jumps (stepping off a box, landing, immediately jumping) create massive forces that can injure unprepared tissues.

Risk Factors:

• Achilles tendon injury
• Patellar tendon stress
• ACL/MCL injury
• Shin splints
• Requires strength base and technique

Proper Progression

1. Build strength first (squat at least 1.5x bodyweight)
2. Start with low-impact plyos (pogo hops, low box jumps)
3. Master landing mechanics
4. Progress box height gradually
5. Limit volume (quality over quantity)

---

Full Sit-Up with Anchored Feet

The Problem

Anchoring feet shifts the exercise from abs to hip flexors, which pull on the lumbar spine. Combined with spinal flexion, this stresses the lower back.

Risk Factors:

• Lower back strain
• Hip flexor dominance
• Psoas tightness
• Minimal core activation

Better Alternatives

• Hollow body hold (anti-extension)
• Dead bugs (prevents hip flexor dominance)
• Hanging knee raises (if hip flexors not an issue)
• McGill curl-up (research-backed, spine-safe)

Exercises That Aren't "Bad"—Just Often Done Poorly

Deadlift

Not bad when: Proper form, appropriate load, gradual progression Becomes problematic: Rounded back, ego lifting, poor setup

Squat

Not bad when: Appropriate depth for mobility, good form Becomes problematic: Excessive forward lean, knee cave, butt wink

Overhead Press

Not bad when: Adequate shoulder mobility, proper bar path Becomes problematic: Excessive back arch, limited mobility compensated

Box Jumps

Not bad when: Appropriate height, proper landing Becomes problematic: Too high (injury risk), stepping down (missing eccentric benefit) or jumping down (excessive impact)

General Principles for Exercise Selection

Replace High-Risk Exercises When:

• You have a history of injury in that area
• The exercise causes pain or discomfort
• Safer alternatives achieve the same goal
• You can't maintain proper form

Consider an Exercise Worth the Risk When:

• It's specifically required for your sport
• You have the prerequisites (mobility, strength, coaching)
• Benefits clearly outweigh alternatives
• You can perform it with excellent technique

How to Evaluate Any Exercise:

1. What's the goal? (What muscle/movement are you training?)
2. Is this the safest way to achieve that goal?
3. Do you have the prerequisites? (Mobility, strength, skill)
4. Can you do it with good form?
5. Does it cause any pain or discomfort?

Key Takeaways

1. "Bad exercises" often aren't universally bad—they're problematic for many people or frequently done incorrectly

2. Safer alternatives usually exist—if an exercise has high risk, there's probably a lower-risk option

3. Individual factors matter—your anatomy, injury history, and goals determine what's appropriate for you

4. Form and load matter more than exercise selection—a "safe" exercise done poorly becomes risky

5. Progress gradually—many problems come from doing too much too soon

6. Pain is information—if an exercise hurts, find an alternative

7. Question tradition—"We've always done it this way" isn't a good reason to continue risky exercises

The goal is effective training that builds you up without breaking you down. Choosing appropriate exercises is part of training smart for the long term.
