6. Extension Stretch
Lying on your belly, prop yourself up onto your forearms with your feet and legs on the floor. Keep your core active and your back relaxed. Don’t extend up into full cobra position, just stay in the easy forearm stage, breathe and stretch your lower back.

7. Bridge
Lie on your back with the soles of your feet flat on the floor and your legs hip width apart. Everything should be aligned so your legs, feet and spine are all point in the same direction. Push into the ground with your feet as you lift your back as high as you can off the floor.
