Did you know that people that sit most of the day will often sleep in a side lying position with their legs positioned similar to sitting.

If this sounds like you, it may be time to start stretching your hip flexors.

Give this stretch a try:

Start in a kneeling position.
Step your left foot out flat on the floor keeping your foot out further than your knee.
Lean forward with your right knee stretched back behind you.
Place your hands on the front thigh just above the knee and push away arching the body back (you can do this next to a chair to help your balance if you need it).
Repeat this to the other side.

Start with a short session and hold the position with a moderate stretch. Gradually, increase the duration and intensity of the stretch over time.
