• Resistance bands and weights are optional to increase resistance and develop muscle mass and strength.

• A hip mobility exercise that strengthens as well as stretches.
  

Type: Strength
 

• Main Muscle Worked: Glutes, Hamstrings, Adductors, Calves
• Equipment: Body Only

Recently I have been back to my physiotherapy appointment.
It took me quite some time to get the point why I have to get my heads-down in a slump position for the  sciatic nerve exercise along my leg. Its incredible to find out if my head is not heading down, my brain only connect to get reaction along my neck.
I also learned another exercise to stretch my femoral nerve which is more on the side of my leg. 
Anyway, my notes of these two exercise are recorded as following:

Neural mobility SLUMP for Sciatic Nerve Stretch
Sit down on a chair or a stool. Put your hands together behind your back, allow your lower back to slouch and bend your head forward.
Slowly straighten one leg as you pull your toes towards you and maintain the position when you feel a gentle stretch. Repeat 10 times
Then repeat ex as above, but move the foot in and outwards (moving from the ankle, not rotating the whole leg). Repeat 10 times
Alternative way: to have the toes move up and down then ankle to move left and right while having the leg at stretch position.
Prone knee bend glide for Fermoral Nerve Stretch
Lie on your side with your your bottom knee bent in front of you to protect your back.
Reach back and grasp your top ankle and gently pull your ankle towards your buttocks (bending the knee).
Move your knee back without arching your back until you feel a stretch in the front of your thigh.
Now move your head down (so your chin touches your chest) and then up (so chin moves away from chest).
Repeat the head movement 10 times.
Rest and repeat 3 times, spread out during the day
