Gyms should grade also 6-8 m routes

One big downside with climbing the 12 - 18 m long gym routes, slightly progressively harder, is that most of us get so pumped that we need to rest at least 15 min. In other words, you seldom climb more than 100 m during your normal session. If you instead would divide your training on 6 - 8 m routes you would only need to rest a couple min in between and you could end up with double as much training. Further more, such training could be defined as power-endurance training which normally is the strength we are all looking for outdoors. Surely, it is just up to you and me to stop midways up the route but it is not so easy to be the first to implement such training in the gym. In general, it is the hardest routes in the gym that gets the less traffic but possibly the 7c might just be 7a up to 7 meters etc. From the kids and the beginners perspective, it is just very natural that before you start climbing the 12 m routes, you progress meter by meter.
