Weighted Seated Leg Raise
The Weighted Seated Leg Raise primarily works the Iliopsoas, with secondary activation of the Adductor Brevis, Adductor Longus, Pectineus, Sartorius, Tensor Fasciae Latae and stabilizer support from the External Obliques, Rectus Abdominis, Rectus Femoris. It is a none isolation exercise at intermediate difficulty.
The Weighted Seated Leg Raise is an intermediate isolation exercise, following a flexion movement pattern. It primarily targets the Iliopsoas, with secondary engagement of the Adductor Brevis, Adductor Longus, Pectineus, Sartorius, Tensor Fasciae Latae. This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Muscles Worked
The Iliopsoas is the primary mover, taking on the bulk of the workload throughout the full range of motion. The Adductor Brevis, Adductor Longus, Pectineus, Sartorius, and Tensor Fasciae Latae act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The External Obliques, Rectus Abdominis, Rectus Femoris act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Iliopsoas (hip_flexors)
Secondary Muscles
- Secondary Muscle Adductor Brevis (adductors)
- Secondary Muscle Adductor Longus (adductors)
- Secondary Muscle Pectineus (adductors)
- Secondary Muscle Sartorius (hip_flexors)
- Secondary Muscle Tensor Fasciae Latae (hip_flexors)
Stabilizer Muscles
- Stabilizer Muscle External Obliques (core)
- Stabilizer Muscle Rectus Abdominis (core)
- Stabilizer Muscle Rectus Femoris (quadriceps)
How to Perform
Preparation
- Sit on edge of bench with legs extended to floor.
- Place weight between ankles.
- Grasp edge of bench.
- Lean torso back and balance bodyweight on edge of bench.
Execution
- Raise legs by flexing hips and knees while pulling torso slightly forward to maintain balance.
- Return by extending hips and knees and lean torso back to counter balance.
- Repeat.
Comments
- Heels may make contact with floor to maintain balance at bottom of movement.
- Rectus Abdominis and Obliques onlycontract dynamicallyif actual waist flexion occurs.
- With no waist flexion, Rectus Abdominis and External Oblique will only act to stabilize pelvis and waist during hip flexion.
- It may be necessary to completely flex hips before waist flexion is possible.
- Exercise can be performed without added weight until more resistance is needed (SeeSeated Leg Raisewithout weight).
- Also known as Weighted Knee Tuck across bench.
- Also seeSpot Reduction MythandLower Ab Myth.
Tips & Common Mistakes
- Control the eccentric phase — the lowering portion drives significant muscle development.
- Avoid momentum; focus on feeling the target muscle work through the full range.
- Full range at both ends maximizes stretch at the bottom and contraction at the top.
Programming Suggestions
Adapt your sets and reps to your training goal.
| Strength | 3–4 sets × 6–8 reps at 75–85% 1RM with 90–120 seconds rest. |
|---|---|
| Hypertrophy | 3–4 sets × 10–15 reps at 60–75% 1RM with 60–90 seconds rest. |
| Endurance | 2–3 sets × 15–25 reps at 40–60% 1RM with 30–45 seconds rest. |
