The backspin is one of the oldest breakdance moves around. It's not too difficult to perform if you know what you're doing. They can be done many ways, but this how I do em (counter clockwise).
Start sitting on your ass with your legs straight in front of you. Now spread them out a bit and turn your upper body to your left. Take that right leg and rotate and bend it a bit so that your lower leg is off to your right side with the knee is pointing straight ahead. Your sole of your right foot should point exactly to your right. This position is similar to the one you go into to stretch your thigh.
What you do next is lower your upper body down to the ground so that your left shoulder is touching and resting on the floor. Do not do anything with your legs yet. Next, extend that bent right leg and swing it left over your left leg. As it passes over the left leg, bring it up and back around to the right so it makes a big circular arc. As you kick it to the right, kick your left leg to the left in a small clockwise circle and then tuck them both in as the force of your legs rolls you back onto your upper back.
You should roll as high as possible on your back. If you find yourself
spinning off onto your right side or your left side after a rotation or two, try
altering the amount you have your legs on that side tucked in. Eg. If you are
spinning onto your right side, try not to tuck the right leg so much and tuck
the left one a bit more. You can work this into your sixstep at step one.
Extend your left leg like normal, but then let yourself fall on it and then kick
the right leg over and around like described above.
