In general yes you can and probably should. However it depends on what you are training for. If you were training to run a 50km race then the ARC training will not really increase your running fitness but it can be a good recovery workout. If you are training for along alpine rock climbs then this ARCing is very important base training for that goal. I suggest including all training into your training log by zone. As to how much benefit there is from it: You can see that this is not a simple back and white question. Be consistent though. That’s the most important thing.
