In reply to edhawk21:
For warm-up I've done various things over the years e.g. 15min jogs and more recently a bit of dynamic stretching, shoulder rotations, leg swings and the like.
While it would be idea to warm-up like this, in practice I don't think it makes it makes *that* much difference, if, as an alternative, you just start of climbing really easy.
I climb at about 7a o/s level.
At my local 12m wall typically I'll do maybe 7(9) warm-up routes on a 12m wall...
1) 2x laps of a F5+
2) 2x laps of a 6a
3) easy 6b
4) 6b+
5) 6c
6) 6c o/s or 6c+ repeat
7) 6c+ repeat or easy 7a repeat
then rest for 15min before continuing the session
At 20m+ high Ratho where the routes tend to be less fierce it's 3 or 4 routes...
1) 6a
2) 6b
3) 6c
4) easy 7a repeat
then rest for 30min before continuing the session
I do generally do static stretches to warmdown and keep an iffy back in check and some theraband shoulder work.
