Here's your first exercise...Pelvic Curls.
If there was one thing that I would tell everyone to do every.single.day, it would be this.
Why? So many benefits - gets your back moving; butt strength (supports your lower back); hip opener (makes moving your back more comfortable); opportunity to add in loads of toys to keep it interesting and add more benefits
How do you do it? Lie on your back with your knees bent and feet at hip width apart. Inhale and squeeze your abs so that your lower back flattens into the mat and your pelvis tilts.
As you exhale, sequentially peel each vertebra off the mat until your whole body is lifted off the mat. You should have a straight line from knees to hips to collar bones.
Inhale and as you exhale, sequentially place each vertebra back down to the mat. The last thing you'll do is return your bottom to the floor and release the tilt in your pelvis.
You can add in leg lifts, knee squeezes, arms..the list is endless. Want a variation - try this video with a squishy ball.
NB - got osteopenia or osteoporosis? Ignore the sequential up and down of the vertebrae and focus on driving the hips straight up and down.
