HANGING LEG RAISE
The hanging hip flexor raise is a great overall movement to train hip and trunk flexion at lengthened ranges. It will also improve grip strength (unless you want to bias the hip flexors fully and use ab straps) and general shoulder endurance. General prescription: 3-5 sets, 5-20 reps.
SUPINE CRUNCH
The supine crunch can be extremely useful in early hip and low back rehab to improve the low load strength and endurance of the core without aggravation of injury. General prescription: 3-4 sets, 5-20 reps.
DEAD-BUG
The dead-bug is a classic staple exercise in early hip and low back rehabilitation to train a neutral spine and trunk stability whilst the upper and lower limbs move. The hip flexors can be strengthened extremely well using this exercise, if technique is kept strict. General prescription: 3-5 sets, 5-15 reps each side.
BIRD-DOG
The bird-dog is a classic staple exercise in early hip and low back rehabilitation to train a neutral spine and trunk stability whilst the upper and lower limbs move. General prescription: 3-5 sets, 5-15 reps each side.
