Here's a crafty bit of exercising. Sorry about the gnome outfit, but hopefully you will understand the photos. People are continually arguing about specific exercises like pull ups being useless, and that out sport of climbing is movement based, well you know what, just argue away, and I'll get stronger. Guys who run the hundred meter dash, do squats, how about that!
If you follow the photos, it might become obvious to you that there is a sticking point here, in this one. This is definitely a fail point on a route. It's mainly down to shoulders, but timing and twisting strength come heavily into play.
The last final bit is a very nice triceps push. You can make this very much harder by slowing bits down, or changing position and height of feet.
More fun and success is what I'am after. There are a few interesting names asssociated with exercises like the 'Egyptian move' in climbing, which is very hard to do for a lotta people, and strangely, practice in isolation makes it very much easier. Another exercise, non climbing, perhaps to many is the 'Turkish getup', I have always liked the Turkish getup, as it uses alotta 'body english'. Anyway now I give you the Arab Spring, it is super good, and leaves me optimistic.
Last photo is 'toeing the line', you do some pull ups, and then rest on your toes, then do more, 10 sets is normally sufficient to make you feel sick. Enjoy!
