Machine hip-flexion movement training the four major hip flexors (iliopsoas, rectus femoris, tensor fascia lata, sartorius), also engaging the abdominals.
Detail
Hip flexion is the listed exercise for the hip flexors. The four major hip flexor muscle groups are the iliopsoas, rectus femoris, tensor fascia lata, and sartorius. Secondary flexors are the pectineus, adductor longus, adductor magnus, and gracilis (contributing to hip flexion only between roughly 40 to 50 degrees). The source lists hip flexion under the midsection group (Body Masters machine) where the abdominals/obliques are engaged. Shortening of the iliopsoas increases lumbar lordosis, so strong abdominals are needed to counter low-back strain.
Key facts
- Primary (4 hip flexors): Iliopsoas, Rectus Femoris, Tensor Fascia Lata, Sartorius.
- Secondary flexors: Pectineus, Adductor Longus, Adductor Magnus, Gracilis (40-50 degrees).
- Also engages the rectus abdominus and external oblique as a midsection exercise.
