Or, now that I'm thinking about it, maybe there is just a bit of a tense trace of that air mattress in my back ....
And just in case you have some aches and pains from the weekend or otherwise, here are two of my favorite stretches.
The first one must be the Calf Stretch the restorative exercise way:
Make sure that your feet don't turn out and keep your hips square. Try to relax your quadriceps muscles so that your knee cap is released. Hold it for 30second and work up to holding it for 1minute or longer.
This is just the BEST! And maybe you can feel it all the way into your lower back.
The other one that can even be done while lying in bed is the Crescent Stretch and it stretches the side of your torso (obliques) and you can even get some IT band action if you are lucky.
Lie on your back with your arms and legs extended. Check if your bra line is touching the floor: your rib cage should ideally have contact with the floor (unlike mine in the pic). You can put a pillow or two under your head to help. Make your shoulder blades nice and wide as well.
Then do this:
Start forming a crescent or c-shape with your body and as you do it focus on getting your hip further away from your rib cage - to really lenghten the side of your torso.
Then just plonk the outside foot over the inside foot and .... breathe.
Hold both of these stretches for at least 30 secs, ideally for a minute and by all means for longer. And I know it's unnecessary to add but ... stretch the other calf and the other side of your body, too.
