There's a really great drill for training your body to land with the foot under the pelvis and it's fun. SKIPPING!! After you warm up for 5 min, skip for 30 seconds, concentrate on landing with your foot under your pelvis and lifting the opposite knee quite high with that foot almost tucked up to your sit bones. The skipping strides should be very short and compact forward to bakc. After skipping for 30 sec, jog for 2 min, repeat until you've got 5 to 10 min left in your workout and then finish off with a cool down of light jogging. this is best done on a track or in a grassy field.
