Back Squat vs. Deadlift: Which Should Be Your Lower Body Focus?

When it comes to building lower body strength, two lifts stand out above the rest: the back squat and the deadlift. Both are staples in SPC programming, but they work the body differently — and depending on your goals, one might take priority over the other.


The Back Squat

What it is:
A barbell squat with the bar resting across the upper back (traps). Performed through a controlled bend at the hips and knees until the thighs are at least parallel to the floor, then driven back up.

Primary muscles worked:

  • Quadriceps

  • Glutes

  • Hamstrings (secondary)

  • Core stabilisers

Key benefits:

  • Builds serious quad and glute mass

  • Improves sprinting, jumping, and change of direction

  • Strengthens core and spinal erectors for posture and stability

SPC tip: If you struggle with depth or knee comfort, we often use a box squat variation first to nail form and build confidence.


The Deadlift

What it is:
A barbell lift starting from the floor, where the bar is pulled up to a standing position by extending the hips and knees.

Primary muscles worked:

  • Glutes

  • Hamstrings

  • Spinal erectors (lower back)

  • Lats and traps (upper back)

Key benefits:

  • Builds hamstrings, glutes, and back muscles

  • Improves grip and forearm strength

  • Mimics real-life lifting from the floor safely and powerfully

SPC tip: If you have a history of back discomfort, trap bar or Romanian deadlifts can offer the same benefits with less spinal load.


Which Is Better for You?

Goal: Bigger quads and leg power
Recommendation: Back squat
Why: Targets quads more directly and loads the knee joint through a large range of motion

Goal: Stronger posterior chain
Recommendation: Deadlift
Why: Focuses on glutes, hamstrings, and spinal erectors for pulling strength

Goal: Sports performance
Recommendation: Both
Why: Squats improve drive and jumping, deadlifts enhance acceleration and balance

Goal: General strength and health
Recommendation: Both
Why: Each works different muscle groups for complete lower body strength


How SPC Uses Them

At SPC, we cycle squat and deadlift variations across training blocks so members develop balanced strength:

  • Some blocks focus on back squats as the main lift with deadlifts as accessories

  • Other phases flip the focus, putting deadlifts front and centre

  • Accessory work ensures you’re building both quads and posterior chain, no matter which lift is primary


Final Takeaway

You don’t need to choose between the back squat and deadlift forever — both have their place in a well-designed program.

Think of them as teammates, not rivals:

  • Squats push weight through the ground

  • Deadlifts pull weight from the ground

Together, they’ll make you stronger, more athletic, and more capable in the gym and in life.
