Here for your enjoyment some yoga / stretch / fitness exercises from Stan Lee’s STRENGTH & FITNESS book.

A few stretches in the morning and/or evening can go a long way. You don’t necessarily have to jump like Silver surfer, in fact, maybe you shouldn’t jump first thing, but do adopt a little morning routine to wake your body gently and activate your vitals so you can kick ass all day. Make it indispensable and obvious like a shower (let’s hope you do shower from time to time). In the evening, stretching will help you lose the tight uniform of a hero, so you can regenerate at ease, make room for new moves and ideas, sleep well, and be fit to kick ass again tomorrow.

The exercise below, the Jameson Roar, is a take on Simhasana, the Lion pose, in Yoga (as shown here also by BKS Iyengar). It is for me a MUST in morning stretch, very accessible and rewarding. It opens your face, brightens your vision, takes away tension in the jaws and at the back of the neck. Interesting for people with bruxomania (compulsive grinding of teeth in sleep) AND very interesting to practice before giving a speech 

When bending forward and letting your head hang like Spiderman below, you might want to flex your knees, to go easy on them and your legs if you are not very flexible (you should not feel pain). Certainly flex your knees on the way up, even if you’re flexible, and rise up slowly, vertebra after vertebra, from the sacred to the cervical region where your head rests. Once you are standing, see that your shoulders are in a good alignment, not falling in front, not too much in your back, and keep them low (you ARE strong, no need to brag about it more).
