The Big 3: Squat, Bench, Deadlift Guide

The squat, bench press, and deadlift are the three lifts that matter most for building strength. Master these, and everything else gets easier.

This guide covers proper technique, common mistakes, and practical fixes for each lift.

The Squat

The squat is the king of lower body exercises. It builds your quads, glutes, and core while developing full-body strength and coordination.

Proper Squat Form

Setup:

1. Position the bar on your upper traps (high bar) or rear delts (low bar)
2. Grip the bar just outside shoulder width
3. Squeeze your shoulder blades together
4. Unrack and take 2-3 steps back
5. Feet shoulder-width or slightly wider, toes pointed out 15-30°

Descent:

1. Take a deep breath and brace your core
2. Break at the hips and knees simultaneously
3. Keep your knees tracking over your toes
4. Descend until hip crease passes below knee (parallel or below)
5. Maintain a neutral spine—no rounding or excessive arching

Ascent:

1. Drive through your whole foot—not just heels
2. Keep your chest up and back tight
3. Knees continue tracking over toes
4. Exhale at the top or through the sticking point
5. Fully extend hips at the top

Common Squat Mistakes

Knee cave: Knees collapse inward during the ascent. Fix: strengthen glutes, cue "spread the floor," and reduce weight until pattern is fixed.

Good morning squat: Hips shoot up faster than shoulders. Fix: strengthen quads, keep chest up, and consider front squats to reinforce upright posture.

Butt wink: Lower back rounds at the bottom. Fix: improve hip mobility, widen stance slightly, or limit depth to where you maintain neutral spine.

Falling forward: Heels come up, weight shifts to toes. Fix: improve ankle mobility, elevate heels with plates or squat shoes, and practice tempo squats.

Squat Cues That Work

• "Spread the floor" (activates glutes)
• "Chest up, elbows down"
• "Sit back and down"
• "Drive your back into the bar"
• "Big breath, tight core"

Squat Variations

• High bar: More quad-dominant, requires more ankle mobility
• Low bar: More hip-dominant, allows heavier loads
• Front squat: Extreme quad emphasis, builds core strength
• Box squat: Teaches proper depth, reduces stretch reflex
• Pause squat: Builds strength out of the hole

The Bench Press

The bench press is the standard for upper body pushing strength. It builds your chest, shoulders, and triceps.

Proper Bench Press Form

Setup:

1. Lie on the bench with eyes directly under the bar
2. Grip the bar slightly wider than shoulder width
3. Squeeze your shoulder blades together and down
4. Create an arch in your upper/mid back (not lower back)
5. Plant your feet firmly on the floor
6. Five points of contact: head, upper back, glutes, left foot, right foot

Unrack:

1. Take a deep breath
2. Unrack with help or by pressing straight up, then out
3. Position the bar over your shoulder joint with arms locked

Descent:

1. Lower the bar with control—not a free fall
2. Tuck elbows to approximately 45° (not flared at 90°)
3. Touch your lower chest/sternum area
4. Maintain your arch and leg drive throughout

Press:

1. Drive the bar up and slightly back toward your face
2. Bar path should be a slight diagonal, not straight vertical
3. Press through the sticking point (2-4 inches off chest)
4. Lock out fully with bar over shoulder joint

Common Bench Press Mistakes

Flared elbows: Elbows at 90° stress the shoulders. Fix: tuck elbows to 45-75° depending on grip width and arm length.

Bouncing the bar: Using momentum off the chest cheats the movement. Fix: pause briefly on the chest or control the descent to a 2-second count.

Flat back: No arch means less leg drive and a longer bar path. Fix: actively squeeze shoulder blades and create upper back arch before unracking.

Losing tightness: Shoulder blades come apart during the press. Fix: set up tighter and don't press the bar straight up (press up and back).

Feet dancing: Moving feet during the lift leaks power. Fix: plant feet firmly before unracking and keep them locked throughout.

Bench Press Cues That Work

• "Bend the bar" (activates lats)
• "Leg drive through the floor"
• "Touch low, drive up and back"
• "Squeeze your shoulder blades in your back pocket"
• "Break the bar"

Bench Press Variations

• Close grip: More tricep emphasis
• Wide grip: More chest emphasis (use cautiously)
• Pause bench: Builds strength off the chest
• Spoto press: Stop 1 inch off chest, builds lockout strength
• Larsen press: Feet up, reduces leg drive, isolates upper body

The Deadlift

The deadlift is the ultimate test of full-body strength. It works everything from your hands to your feet, with emphasis on the posterior chain—glutes, hamstrings, and back.

Proper Deadlift Form (Conventional)

Setup:

1. Stand with feet hip-width apart
2. Bar over mid-foot (about 1 inch from shins)
3. Grip the bar just outside your legs (double overhand, mixed, or hook grip)
4. Bend at the hips and knees until shins touch the bar
5. Chest up, shoulders over or slightly in front of the bar
6. Neutral spine—slight arch in lower back is fine, rounding is not

The Pull:

1. Take a deep breath and brace hard
2. Push the floor away (think leg press, not back extension)
3. Keep the bar tight to your body—drag it up your legs
4. Extend hips and knees at the same rate
5. Once bar passes knees, drive hips forward
6. Stand tall with shoulders slightly back, knees locked

The Descent:

1. Push hips back first (like a Romanian deadlift)
2. Once bar passes knees, bend knees to lower it
3. Control the descent—don't drop and don't do a super slow negative
4. Reset position between reps (touch and go is for conditioning, not strength)

Common Deadlift Mistakes

Rounded back: Lower back rounds under load. Fix: strengthen core, practice hip hinge pattern, reduce weight until you can maintain neutral spine.

Bar drift: Bar travels away from the body. Fix: cue "drag the bar up your legs," focus on keeping lats engaged.

Hips rising first: Back angle gets more horizontal before bar moves. Fix: strengthen quads, cue "push the floor away," consider deficit deadlifts.

Hitching: Using legs/thighs to bump the bar up near lockout. Fix: strengthen glutes, avoid pulling weight you can't complete smoothly.

Overextension: Leaning back excessively at lockout. Fix: cue "stand tall," squeeze glutes, stop when hips are fully extended.

Deadlift Cues That Work

• "Push the floor away"
• "Drag the bar up your legs"
• "Chest up, hips down"
• "Engage your lats" (protect the armpits)
• "Drive your hips through at the top"

Deadlift Variations

• Sumo: Wider stance, more quad/adductor emphasis
• Romanian deadlift: Hamstring focus, no floor contact
• Deficit deadlift: Stand on plates for longer ROM
• Block pull/Rack pull: Partial ROM for overload
• Pause deadlift: Build strength off the floor

Programming the Big 3

Frequency

Most lifters benefit from training each lift 1-3 times per week:

• Beginners: 2-3x per week per lift (full body programs)
• Intermediates: 1-2x per week per lift
• Advanced: Variable, often using variations

Rep Ranges

For strength development with the Big 3:

• Primary work: 3-6 reps per set at RPE 7-9
• Volume work: 6-10 reps per set at moderate intensity
• Technique practice: 3-5 reps at 60-70% focusing on form

Progressive Overload

Apply progressive overload to the Big 3 just like any other lift:

• Add 2.5-5 lbs to upper body lifts when you hit rep targets
• Add 5-10 lbs to lower body lifts when you hit rep targets
• Track your PRs and aim to beat them over time

Iridium tracks your personal records across all three lifts and shows your strength progression over time—so you always know where you stand.

Safety Considerations

Squat Safety

• Use safety bars/pins set just below your deepest squat position
• Learn the bail: dump the bar backward and step forward
• Never squat to failure without safeties

Bench Safety

• Use safeties or have a competent spotter
• Learn the roll of shame as a backup
• Never bench to absolute failure alone without safeties

Deadlift Safety

• This is the safest to fail—just drop the bar
• Use bumper plates if dropping from lockout
• Never jerk the bar off the floor; build tension first

The Bottom Line

The squat, bench press, and deadlift are foundational lifts. They're not the only exercises that matter, but they're the ones that build the most strength per minute invested.

Master the technique first. Add weight gradually. Track your progress. Be patient.

These three lifts can take you from beginner to advanced with nothing else—but doing them right matters more than doing them heavy.
