In reply to Will1991:
to start: i climb mostly ice and alpine, with trad and sport filling the gaps in summer.
a boulderer would have a very different attitude (and hair cut probably).
i go about 4 times a week for 2-3hr sessions each time.
i make it an endurance thing: non-stop, rest on the bike.
i use crossfit and gym jones as a model but subscribe to neither.
i do sets of combining exercises that stress different aspects, with one exercise of the lot being high stress and one being resting stress.
and i focus on a particular aspect till i feel ive hit saturation, ie hauling related muscle groups, full body integration, fore arm strength etc etc.
i attempt to activate large core muscle groups that extend to the extremities with exercises like GHD situps with a raised leg and weighted row.
where i can i off set the weight/stress.
i almost never use machines - only if im carrying an injury.
so, yesterdays session (im training for high alt alpine) was:
warm up with dumbells (squats, presses etc) & standing rows.
complex of pull ups, backsquats, pushups and DB presses.
complex of hanging leg raises, DB pistons and backsquats.
GHD off set rows with weights (front and side).
complex of lat presses, bench presses, standing rows and bench leg raises.
130 kcals on bike, maximum resistence, standing position.
running machines bore me to tears, but i run for 2+hrs a day when i dont go to the gym.
rowing machines are great for stress work. wish i had access to one.
in the past i used a weighted sprint sled and large diameter rope hauls and found it good, but dont have access to them now (wish i did)
im sure people will pull all this apart and tell me its bullshit, but im seeing significant progress in lots of ways across other pursuits as well (mountain ultras and rescue).
and yes im addicted to it and probably think into it too much, but hey, i dont hassle others for their addictions that are far less rewarding in my eyes.
