A strong Nordic Curl repetition begins before you move: the setup determines whether the right muscles can do their job. The exercise mainly trains biceps femoris, while glutes and erector spinae help support and control the movement. You will use a Nordic bench while working from prone or forward-supported on the station.
What makes a good Nordic Curl repetition?
Control the hip and knee angles so tension stays on the back of the thighs throughout the rep. This movement asks for strong positional control, coordination, or relative strength across several phases. Learn each position first and add load only when the sequence stays smooth.
Muscles worked
Primary
Biceps femoris
These muscles should carry most of the intended work when the setup and movement path stay consistent.
Supporting
Glutes and Erector spinae
These muscles assist the movement or help keep the rest of your position steady.
Set up before you move
Start from prone or forward-supported on the station. Use the prescribed grip: supinated. Check that a Nordic bench is secure and adjusted before you begin.
Step-by-step tutorial
How to do Nordic Curl
- 1
Set the starting position
Set the knees at the machine or bench pivot, secure the ankles, brace the trunk, and begin Nordic Curl with the hips aligned to the support.
Breathing: Breathe steadily; do not hold your breath.
- 2
Perform the effort phase
Exhale and flex the knees, drawing the heels toward the body while preventing the hips from lifting or the lower back from arching.
Breathing: Exhale through the effort.
- 3
Control the end position
Control the shortest hamstring position that can be reached without losing hip or trunk alignment.
Breathing: Breathe steadily; do not hold your breath.
- 4
Return under control
Inhale and extend the knees slowly, resisting the load until the hamstrings return to a lengthened starting position.
Breathing: Inhale through the controlled return.
Common mistakes to avoid
Starting before the setup is stable
Do not rush the first position. Set the knees at the machine or bench pivot, secure the ankles, brace the trunk, and begin Nordic Curl with the hips aligned to the support. Make that setup feel repeatable before adding speed or resistance.
Letting the working position drift
Keep your prone or forward-supported on the station setup consistent through the rep and maintain the supinated. If another part of the body has to swing or twist, reduce the load or range.
Rushing the return
The return is part of the exercise, not a pause between efforts. Inhale and extend the knees slowly, resisting the load until the hamstrings return to a lengthened starting position.
Forcing a range you cannot control
Use the Nordic Curl setup, maintain controlled joint alignment, and stop if the movement causes pain.
Sets, reps, and rest
Start with 2–4 sets of 10–15 smooth repetitions. Rest 45–90 seconds between sets. Use enough resistance to feel the target muscles without shortening the range or borrowing momentum from the rest of your body.
Treat this as a starting framework. Your load and volume should match your current technique, recovery, and training plan.
Nordic Curl questions
Is Nordic Curl suitable for beginners?
Nordic Curl is classified as an advanced-level movement in this guide. This movement asks for strong positional control, coordination, or relative strength across several phases. Learn each position first and add load only when the sequence stays smooth.
What muscles does Nordic Curl work?
Nordic Curl primarily works biceps femoris, with glutes and erector spinae assisting or stabilizing the movement.
What equipment do I need for Nordic Curl?
You need a Nordic bench. Set everything up securely before the first repetition.
