Compound — posterior chain
Barbell or dumbbells
The Romanian deadlift is one of the best exercises for the hamstrings and glutes. It delivers a deep stretch in the hamstrings and builds the posterior chain that matters in every sport.
Muscles worked
The Romanian deadlift is the most efficient hamstring builder most people can do, because it loads the muscle in a stretched position — the condition research consistently links to growth. It also teaches the hip hinge, which is the movement pattern behind the deadlift, the kettlebell swing and safe lifting in general.
Technique
Common mistakes
Squatting the weight down instead of hinging
Fix: The knees should stay in roughly one position. Push the hips back toward the wall behind you and let the bar travel down your thighs.
Going too low and rounding the lower back
Fix: Depth is set by your hamstring flexibility, not by the floor. Stop the moment your back starts to round — usually mid-shin.
Letting the bar drift away from the legs
Fix: Keep it grazing your thighs. Every centimetre forward multiplies the load on your lower back.
Treating it like a max-effort lift
Fix: The RDL is a hypertrophy exercise. Loads that force sloppy positions defeat the purpose — control the eccentric for 3 seconds instead.
Sets and reps
How to progress
Add reps before weight — 3 sets of 8 becoming 3 sets of 12 is a real gain. When you do add load, 2.5 kg at a time is plenty. Because the RDL loads the stretch so hard, it produces more soreness than most exercises: introduce it gradually and expect two weeks of adaptation.
Variations
Single-leg RDL
Huge balance and stability demand, and it corrects side-to-side differences. Start with no weight at all.
Dumbbell RDL
Lets the weights travel outside the knees, so taller lifters get more range.
Deficit RDL
Standing on a low platform increases the stretch for people who already have good flexibility.
Frequently asked questions
The RDL keeps a fixed slight knee bend and stops above the floor. The stiff-leg version uses straighter legs and a longer range, often from the floor. The RDL is more hamstring-focused and easier on the back.
No. The RDL is a top-down movement and the rep ends when your hamstrings run out of range, typically mid-shin. Touching the floor usually means the back has rounded.
Almost always too much weight or too much depth. Reduce both, keep the bar against your legs, and consciously push the hips back rather than lowering the chest.
