What Is a Good Deadlift?

The deadlift is the most comprehensive test of full-body strength — simultaneously loading the posterior chain (hamstrings, glutes, spinal erectors), upper back (traps, rhomboids), grip, and core. It is the highest-load lift for most people and the best single predictor of total body force production.

Deadlift Strength Standards (1RM by Bodyweight, Male)

*Source: Strength Level database, NSCA performance norms. Most people deadlift 20–40% more than they back squat due to the starting-from-rest mechanical advantage.*

*Female lifters: Standards are approximately 65–70% of male values. Women often perform relatively better in the deadlift than bench press due to strong glute and hamstring development.*

Conventional vs. Sumo: Which Produces a Higher 1RM?

Most competitive powerlifters choose based on anatomy. If you have a long torso and shorter legs, conventional tends to be mechanically advantaged. If you have wide hips and shorter torso, sumo.

Key Training Percentages

Three Technical Points That Add Kilograms Instantly

1. Engage the lats before the pull Think "protect your armpits" — actively engaging the lats (visualize bending the bar around your legs) prevents the bar from drifting forward, maintaining a shorter moment arm and protecting the lumbar spine.

2. Push the floor away, don't pull the bar up Mentally shifting to "leg press the floor" rather than "pull" keeps the hips from shooting up too early (the classic "stripper deadlift" error), maintaining leg drive through the first third of the pull.

3. Lock hips and shoulders at the same rate The most common breakdown is hips rising while the bar is still below the knee, converting the pull into a good morning. The hips and shoulders should rise at the same rate from floor to knee, then hips drive through at the top.

Grip: The Underrated Deadlift Limiter

Grip failure is the most common reason recreational lifters miss deadlifts. Options ranked by grip strength: 1. Double overhand (weakest) — symmetric but limits weight 2. Mixed grip (one over, one under) — adds 10–20% load capacity; minor bicep tear risk on underhand arm 3. Hook grip — used by all elite Olympic weightlifters; painful during learning period but eliminates bicep risk 4. Straps — appropriate for accessory work and very high volume sets; do not use for competition-specific work as they prevent grip adaptation

Frequently Asked Questions

How often should I deadlift? 1–2 times per week is optimal for most lifters. The deadlift has the highest systemic recovery demand of the big three lifts. Pulling twice per week (once heavy, once lighter/technique-focused) is the most common evidence-supported frequency.

Why does my lower back round on heavy deadlifts? Usually a combination of: insufficient hamstring flexibility preventing proper hip hinge, setting up with hips too high (creates a squat-to-deadlift), or simply attempting loads above current technical capacity. Work with 70–80% 1RM on technique until neutral spine is automatic before loading heavier.

Should I deadlift if I have lower back pain? This depends entirely on the source and severity. A herniated disc is very different from general lumbar tightness. Consult a sports medicine physician or physiotherapist familiar with barbell training. Romanian deadlifts (with lighter load and controlled tempo) are often prescribed during rehabilitation as they maintain posterior chain strength with reduced spinal loading.
