Finger Jam Technique
Step1
Find a suitable finger crack. A finger crack is just large enough to fit your fingers into.
Step2
Slide the fingers of your top hand in the crack just above your head, with your thumb pointing down.
Step3
Slide the fingers of your bottom hand in the crack in the same way.
Step4
Drop your elbow down toward your side, camming your fingers in the crack. While this may be unpleasant on your fingers, it makes for a solid grip.
Step5
Use your feet on the face or in the crack, whichever is better.
Step6
Push up with your feet and pull with your hands, keeping the elbow dropped and the fingers cammed.
Step7
Move your hands and feet up and repeat.
Hand Crack Technique
Step1
Find a suitable hand crack. A hand crack will accept most or all of your hand snugly.
Step2
Slide your top hand in the crack thumbs down.
Step3
Slide your bottom hand in the crack either thumbs down or thumbs up.
Step4
Drop your elbow down to your side to cam your hand in the crack.
Step5
Place your feet in the crack sideways with the big toes up.
Step6
Stand up on your feet while you pull up with your hands.
Step7
Alternate hands and feet as you ascend.
Fist Crack Technique
Step1
Find a suitable fist crack. A fist crack is 3 to 4 inches wide and will be too big for your hand but too small for your made fist going straight in. It's the most difficult of the jam crack techniques, and these routes often lead to wider climbing known as off-width.
Step2
Place your hand straight in the crack, palm down.
Step3
Close your hand to make a fist. The sides of your fist should press very tightly against the side walls of the crack. If your fist doesn't fit tightly in the crack, it's probably too wide for a fist jam.
Step4
Place your feet in the crack.
Step5
Stand up on your feet as you pull with your hands.
Step6
Alternate hands as you ascend.
