A comprehensive study published in the Journal of Strength and Conditioning Research has finally settled the deadlift vs squat debate, finding that both exercises produce nearly identical total muscle growth when matched for volume and intensity.
The Findings
Researchers tracked 200 trained lifters over 16 weeks. The squat group and deadlift group gained equal total lean mass (3.2 lbs vs 3.1 lbs). However, squats built more quad muscle while deadlifts built more posterior chain.
Practical Recommendation
The researchers recommend including both exercises for complete development. For time-limited lifters, the deadlift provides slightly more "bang for your buck" as it engages more total muscle mass per rep.
- Both produce equal total muscle growth
- Squats: better for quads
- Deadlifts: better for posterior chain
- Deadlifts engage more total muscle per rep
