Stiff-Leg Deadlift

Legs Weight & Reps Barbell
The stiff-leg deadlift is similar to the Romanian deadlift but with straighter legs, placing even more emphasis on the hamstrings. Lower the bar until you feel maximum hamstring stretch.

How to Do Stiff-Leg Deadlift

  1. Stand with the bar at hip height and keep your legs as straight as possible (minimal knee bend)
  2. Hinge at the hips and lower the bar, feeling an intense hamstring stretch
  3. Let the bar travel down past your knees while keeping it close to your legs
  4. Return to standing by driving your hips forward — don't pull with your back

Form Cues

  • Stand with the bar at hip height and keep your legs as straight as possible (minimal knee bend)
  • Hinge at the hips and lower the bar, feeling an intense hamstring stretch
  • Let the bar travel down past your knees while keeping it close to your legs
  • Return to standing by driving your hips forward — don't pull with your back

Common Mistakes to Avoid

  • Locking the knees completely, which can hyperextend them — maintain a very slight, fixed knee bend
  • Lowering the bar too far past your flexibility limit and rounding the lower back
  • Pulling the bar up with the lower back instead of hinging the hips forward

Muscles Worked

Stiff-Leg Deadlift is classified as a compound legs exercise with a hip hinge movement pattern. The sections below break down each muscle that contributes to the lift, with anatomy notes so you can picture what is actually working under the bar.

Primary movers

  • Hamstrings
    Hamstrings — the three-muscle group on the back of the thigh, responsible for both knee flexion and hip extension.
  • Gluteus Maximus
    Gluteus Maximus — the largest muscle in the body, the primary driver of hip extension and the powerhouse of squats and deadlifts.

Secondary & stabilising muscles

  • Erector Spinae
    Erector Spinae — the deep spinal muscles that extend and stabilise the lower back under load.
  • Adductors
    Adductors — the inner-thigh muscles that pull the leg toward the midline, active in wide-stance squats and lunges.
  • Calves
    Calves — the combined gastrocnemius and soleus controlling plantar flexion and ankle stability.

Training Guide

How to program Stiff-Leg Deadlift — sets and reps, weekly volume, when to use it, where it fits in your split, progression, and safety.

Recommended Sets and Reps

Your set and rep scheme should match your goal. Strength work uses heavy loads with long rest. Hypertrophy uses moderate loads with moderate rest. Endurance uses lighter loads with short rest — useful for conditioning and work capacity.

Strength
4-5 sets
3-5 reps
3-5 min rest
Hypertrophy
3-4 sets
8-12 reps
60-90s rest
Endurance
2-3 sets
15-20 reps
30-60s rest

Programming Stiff-Leg Deadlift: Frequency & Volume

Legs demand longer recovery because of the large muscle mass and high neural cost. Aim for 10-18 hard sets per muscle (quads, hamstrings, glutes) per week, split across 2 sessions.

Volume landmarks for legs: roughly 8 sets/week is the minimum effective volume (MEV), 14 sets/week the maximum adaptive volume (MAV), and 20 sets/week the maximum recoverable volume (MRV). Start closer to MEV and add a set per week until you stop progressing, then deload and restart.

Frequency: train legs 2 times per week. Balance quad-dominant work (squats, leg press) with posterior-chain work (deadlifts, RDLs, hip thrusts).

Use the IronStreak volume calculator to audit your current weekly sets across all legs exercises and see where you fall on the MEV → MAV → MRV continuum.

When to Use Stiff-Leg Deadlift

Not every exercise is right for every lifter or every session. The decision tree below helps you figure out where Stiff-Leg Deadlift fits your training.

  • Building raw strength
    Place Stiff-Leg Deadlift first in your session while you are fresh. Work in the 3-5 rep range with long rest periods (3-5 minutes) and focus on linear progression week to week.
  • Building muscle (hypertrophy)
    Run Stiff-Leg Deadlift in the 8-12 rep range with 2-3 minutes of rest. Prioritise controlled eccentrics, a deep stretch at the bottom, and full range of motion every rep.
  • If you have barbell access
    Stiff-Leg Deadlift is ideal for heavy loading and tracking linear progression. If you train at home without a barbell, substitute a dumbbell variation for similar stimulus.
  • If you have 6+ months of training
    You are ready for Stiff-Leg Deadlift. Focus on progressive overload — add small amounts of weight or an extra rep each session while keeping every rep crisp.

Program Placement in Popular Splits

Here is where Stiff-Leg Deadlift typically lives in the most common training splits. Pick the one that matches your weekly schedule.

  • Push/Pull/Legs (PPL) split: Stiff-Leg Deadlift lives on leg day — compounds first, isolation work last.
  • Upper/Lower split: Stiff-Leg Deadlift is a staple of your lower-body days.
  • Full-body split: schedule one heavy leg compound per session and rotate movements across the week.

Progressive Overload Strategy

The simplest way to progress weighted work is double progression: pick a rep range (for example, 3 sets of 8-12). When you hit the top of the range on all sets with good form, add the smallest weight jump available (2.5 kg / 5 lb) and work back up from the bottom of the range. Aim for a ~2% weekly volume increase (sets × reps × weight), or a 0.5-1 kg jump on your top set. When progress stalls, try a deload week, slow the eccentric tempo, or add an extra set rather than piling on more weight.

Safety & Injury Prevention

Leg compounds are among the most demanding exercises in the gym. Warm up with 5-10 minutes of light cardio plus 2-3 progressively heavier warm-up sets. Cue the knees to track over the toes, keep the lower back neutral, and descend to full depth only when mobility allows. Never sacrifice form for weight — a rounded lower back under heavy load is the fastest route to injury.

Frequently Asked Questions

What muscles does the stiff-leg deadlift work?
The stiff-leg deadlift primarily targets the hamstrings and gluteus maximus, with secondary work from the erector spinae, adductors, and calves. The straighter legs increase hamstring stretch compared to the RDL.
How much should a beginner stiff-leg deadlift?
Beginners typically stiff-leg deadlift about 10-15% less than their Romanian deadlift due to the straighter legs. Start with 55-95 lbs (25-43 kg) and focus on the stretch.
Stiff-leg deadlift vs Romanian deadlift — which is better?
The stiff-leg deadlift places more stretch on the hamstrings due to straighter legs, while the RDL allows slightly more weight with a small knee bend. The RDL is generally safer and more popular; the stiff-leg DL is for advanced lifters seeking maximum hamstring stretch.
How often should I do Stiff-Leg Deadlift?
Most lifters train legs 2 times per week. Stiff-Leg Deadlift can feature in every legs session or rotate with similar movements across the week. Aim for 14-20 hard legs sets per week in total, split across the exercises you include.
Is Stiff-Leg Deadlift good for beginners?
Stiff-Leg Deadlift is considered intermediate. Beginners can learn it, but spending 2-3 weeks with light weight before adding significant load is strongly recommended. If you are brand new, consider starting with a machine or bodyweight variation first.
How many sets and reps of Stiff-Leg Deadlift should I do?
For strength, run 4-5 sets of 3-5 reps with 3-5 minutes of rest. For hypertrophy, run 3-4 sets of 8-12 reps with 60-90 seconds of rest. For muscular endurance, run 2-3 sets of 15-20 reps with 30-60 seconds of rest. Track every set in IronStreak to see how your volume and intensity trend week to week.
