Choosing the Best Exercise for Stronger Hamstrings: Hamstring Curls vs. Romanian Deadlifts

Daily Health

27/01/2026

Core Concepts Explained

Hamstrings, located at the back of your thighs, play a vital role in daily movements like walking, climbing stairs, and squatting. Strong hamstrings support knee and hip mobility and help prevent injuries. Two popular exercises for targeting these muscles are hamstring curls and Romanian deadlifts (RDLs). Each activates the muscle group differently and may be more suitable depending on your fitness experience and goals.

Benefits and Potential Risks

Hamstring Curls:

Benefits: Ideal for beginners due to simpler movement mechanics; isolates the hamstrings for direct muscle engagement; can be performed with machines, resistance bands, or bodyweight variations.
Risks: May cause knee discomfort in individuals with knee issues or post-surgery; isolation means less involvement of stabilizing muscles.

Romanian Deadlifts:

Benefits: Trains the entire posterior chain (hamstrings, glutes, and lower back); allows for progressive overload with increased weights; well suited for intermediate to advanced lifters aiming for strength and muscle gains.
Risks: Requires precise technique—incorrect form may risk lower back strain or injury. Individuals with back issues should be cautious. Beginners should start light and consider expert supervision.

Incorporating both exercises can result in stronger, more injury-resilient hamstrings, as noted by strength coaches and physical therapists. Variety helps to train the muscle through different movement patterns (knee flexion and hip hinge).

Supporting Data

Research indicates that comprehensive hamstring training—combining isolation (hamstring curls) and compound (RDLs) exercises—leads to better muscle balance, endurance, and reduced risk of strain or injury (British Journal of Sports Medicine, 2020).

Practical Steps to Maximize Results

Start slow: Begin with lighter weights or bodyweight variations to master the technique.
For Beginners: Prioritize hamstring curls (machine or resistance band versions) for controlled movement.
Progress to RDLs: If you can hold a 30-second plank with good form—an indicator of adequate core stability—it’s safe to introduce RDLs. Practice the hip hinge movement without weights, then add light dumbbells or a barbell once confident.
Form First: In RDLs, maintain a straight back and a soft knee bend; focus on hinging at the hips. For curls, focus on bending the knees to curl your heel toward your glutes—avoid using momentum.
Listen to Your Body: If you feel pain (not muscle fatigue) in your knees or back, re-evaluate your form or consult a fitness professional.
Routine Example: Aim for four sets of 8–10 reps for each exercise. Increase weight gradually once the given weight feels easy.

Including both exercises in your routine under proper guidance offers a balanced and effective way to build stronger hamstrings and support overall lower body health.
