Hyperbolic Stretching
Chin ups are a tough exercise but are well worth the effort. They target the biceps, back, chest and abs among other muscles. If you are unable to do one chin up to start with then you can do negative chin ups. To do a negative chin up you should stand on a chair so that your head is level with the bar. Then grip the bar and slowly lower yourself down to the floor. Try to do 10 of these every day for a week. You will be able to do your first full chin up soon enough.
