Hanging leg raise that works the rectus abdominus together with the hip flexors (iliopsoas, pectineus, rectus femoris).
Detail
Performed hanging from a bar. The source labels iliopsoas a 2-joint muscle ("2m") in the muscle list. Because much of the work is hip flexion, the iliopsoas contracts strongly; the source repeatedly cautions that strong hip-flexor (iliopsoas) involvement in leg-raise/straight-leg movements increases lumbar lordosis and can cause low-back strain, which strong abdominals help counter.
Key facts
- Primary Muscles: Rectus Abdominus, Illiopsoas (2-joint), Pectineus, Rectus Femoris.
- Combines trunk flexion (abs) with hip flexion (hip flexors).
- Strong hip-flexor involvement loads the lumbar spine.
Connections
- rectus-abdominis — trunk flexor.
- iliopsoas — primary hip flexor (2-joint).
- rectus-femoris — hip flexor / knee extensor.
- hip-adductors — pectineus (a secondary hip flexor).
- iliopsoas-lordosis-situp — hip-flexor recruitment and lumbar lordosis caution.

Hip Adductors
The hip adductors are the pectineus, adductor brevis, adductor longus, adductor magnus, and gracilis.Hip Flexors
The 4 major hip flexors — iliopsoas, rectus femoris, tensor fascia lata, sartorius — plus secondary flexors.Iliopsoas
The major hip flexor, made of the iliacus and psoas major; shortening it increases lumbar lordosis.Rectus Abdominis
The "abs"; a long strap-like trunk flexor split into left/right halves by the linea alba.Rectus Femoris
A 2-joint quadriceps muscle that flexes the hip and extends the knee.Iliopsoas, Lumbar Lordosis & Sit-Up Lower-Back Caution
Tight hip flexors increase lumbar lordosis and low-back strain; straight-leg sit-ups and leg raises work the hip flexors and, with too much upward movement, can cause lower-back problems instead of abdominal tone.
