A hangboard is one of the best tools a climber has to increase their finger strength. Whether you are focused on indoor climbing competitions or projecting outdoor rock climbs, at some point you will likely need to focus on getting stronger fingers. But how do you know if it is the right time to start hangboarding? Climbing well involves much more than strong fingers. Think back to the time you saw the "out of shape" climber flash your project outdoors or the "in shape" climber struggle on your warm-up in the gym. Because every climber has a different body with different strengths and weaknesses, it can be difficult to tell what part of your climbing is holding you back. In this article, we will go over some indicators, or "Green Flags," to look out for that will let you know if finger strength is holding you back. We will also point out some "Red Flags" that may indicate that hangboarding isn't for you at the moment.
