Do you have a strict training schedule for when and how you train throughout the year?
No, one day I realized that I like climbing not training. So I try to climb outside as much as possible. On another hand is yoga, trying to practice it three days a week minimum.
What advice can you give to somebody looking to improve their training routine?
Stretch, stretch every day and listen what your body tells.
What do you think of indoor climbing gyms in relation to climbing on actual rock?
Indoor has became another modality inside the climbing world. I used to say that I climb rock, multipitch, trad, sport climbing and bouldering, also ice climbing, but not indoor.... Another world, another stile, lots of show.. I enjoy it for a while, but not as a weekly thing.
Are you able to do a one-arm pull-up? How about a single finger?
How much of the success as a pro climber is due to show and how much due to actual climbing skill?
I believe in effort and work, whether in the climbing wall or the gym, or on the rock, a good climber is one who dedicates time and effort. Abilities? of course they also count, but "whoever follows it gets it"
