Finger holds or crimps vary not only in depth but can restrict the number of fingers you can use. With a closed crimp the fingers will be in an arched position with the thumb across the top of your index finger for support. With an open crimp the fingers will be straighter and the thumb not always able to give support, but look for ways to get added pressure from the thumb. Finger strength takes time to develop, another reason to warm up and progress through the grades.

Large rounded holds are called slopers and require an open handed position. An extended arm keeping the body below the hold is essential. It might be useful to look at, feel and experiment with different holds whilst at ground level, either in the climbing centre or in the the bouldering room if there is one available, in order to see all the possiblities a hold has to offer.

A sloper might have a hidden side pull. An upside down jug becomes an undercut, allowing you to move outwards and upwards.

With some moves you will have to match, or swap hands on the hold in order to free up the other hand. This is also true of the feet. There are several ways to do this, and are similar for both the hands and feet. The terminology may give you a clue: the hop, the tableclothe, the roll and the peeler. Whatever you choose, plan ahead and have fun trying.

As you get familiar with using holds for hands and feet your movement will become more fluid. Many climbers move statically which is secure but limits fluidity. It is the ability to place the foot, transfer your weight onto it and push off with an almost dancelike quality, so there is no beginning or end to the movement, that turns a static climber into one who flows up the wall. Children are naturally dynamic climbers, using their momentum to reach the next hold. A good balance can be found somewhere between the two.
