I've just started indoor bouldering and it's an enormous amount of fun!
But I'm really struggling to get going. I can just-just finish the easiest routes (and not even all of them) and then I'm completely drained.
The wall I'm starting on has a slight overhang (it's just not perfectly vertical), I'm not sure if that's a good thing for a beginner?
Anyway, I've never done anything active in my life, I'm very skinny, and I have zero strength or endurance. My grip goes very very quickly, but I also have a hard time pulling myself up to reach the next hold. I know I'm not supposed to be pulling myself up too much, but even just the effort to stay on the wall while I stand up is way beyond me. I'm struggling too much to really have a clear mind and look around for the next holds and where the route is taking me so I'm unable to improve my mental technique.
So, any advice on exercises I can do at home to supplement my (I guess) 3-weekly bouldering?
I'm traveling for the next 3 to 4 months and will be doing as much bouldering as possible in that time, but I won't have access to gym equipment and would like to do the exercises in my room.
For my grip: I have a rubber grip exerciser but I'm not sure if I should be crunching it repeatedly or rather just holding it for as long as possible? And how hard should I push myself? Can I do exercises and bouldering every day with good nutrition or should I have rest-days inbetween?
TL;DR: Please help a traveling bouldering newbie with next to no strength or endurance out!
