Hi James
I would recommend some exercises like yoga.
Tips:
1) STAY ON YOUR FEET:
Keep your back straight, it will help you connect your abdominal muscles. Take a step forward with your right foot. Lower left knee to the floor and slide backwards until the whole leg is stretched.
2)LIE ON YOUR BACK:
Bring the right knee to the left, rotate the waist and place it on the floor. The right foot should be at right angles, while the left foot does not bend. Stand for a few seconds in this position and repeat with the other leg.
3) LIE ON YOUR BACK:
Raise your right knee to your chest and hold it with both hands. Press to bring it as close as possible. Do not lift your left foot off the floor. Stay in this position for a few seconds and repeat with the other foot.
if those exercises work for you let me know.
