Technique, biomechanics, variations and common errors for the squat, deadlift and bench press, with guidance on choosing variations for different athletes.

- Explain how variations change joint demands
- Identify and correct common errors
- Choose variations based on goals, anatomy and injury history
Before this lesson
Why this matters
The squat, deadlift and bench press are foundational strength exercises. Understanding their mechanics and variations lets you fit them to each athlete.
Squat
Schoenfeld’s review describes how squat depth, stance and bar position influence joint kinetics and muscle activation [schoenfeld2010].
| Variation | Effect |
|---|---|
| Front squat | Upright trunk, more knee demand |
| High-bar back squat | Balanced knee/hip |
| Low-bar back squat | More hip demand, more trunk lean |
| Box squat | Controlled depth, hip emphasis |
Common errors: heels lifting (ankle mobility or stance), excessive knee valgus under fatigue, losing trunk position at depth.
Deadlift
| Variation | Effect |
|---|---|
| Conventional | Hip- and back-dominant |
| Sumo | More upright trunk, more adductor/knee demand |
| Trap (hex) bar | More knee demand, lower lumbar moments, higher power [swinton2011] |
| RDL | Eccentric hip hinge, hamstring emphasis |
Common errors: bar drifting forward, hips rising first, losing spinal position under heavy load.
Bench press
Set-up: eyes under the bar, shoulder blades retracted and depressed, feet planted, controlled descent to the lower chest, press up and slightly back. Errors: bouncing, flared elbows at the bottom, lifting hips [haff2016].
Common mistakes and misconceptions
Case study
A tall volleyball player finds conventional deadlifts uncomfortable. Switching to trap-bar deadlifts allows heavy loading with a more upright trunk and pain-free training, while jump performance continues to improve.

- Choose a deadlift variation for a tall athlete with back sensitivity.
- List three bench press cues and their purpose.
Key takeaways
- Squat variations (front, high-bar, low-bar, box) shift demand between knees, hips and back.
- Deadlift variations (conventional, sumo, trap bar, RDL) differ in hip, knee and spinal demands.
- The trap-bar deadlift shifts load toward the knees and can reduce lumbar demands compared with a straight bar.
- Choose variations to suit the athlete; technique standards should be consistent.
