Better technique through one leg or one arm climbing

Quick decisions and dynamic moves are what counts doing onsights and here is probably where you can improve the fastest. The easiest way is simply climb routes and boulders with just using one arm or one leg. Normally the indoor routes are deliberately build so you can always stay in your comfort zone but this soft training will make you hesitate when some other techniques are needed. Do not do too much training with just one arm as this can make you injure your shoulder and you can also switch arm every five moves or so. Another option is to say that you for the other hand are just allowed to take the smallest holds. If it is routes on your maximum you can use all footholds on the wall. In order to get stronger using just one arm you are also allowed to grab your wrist which actually can be useful also on specific routes. Remember that the more you are just climbing the comfort zone routes in your gym in combination with projecting down personal best, the smaller your move repertoire will get.
