CC, if you have time to add a weight workout to your week, there's a power training routine that is fast and easy that will make a world of difference for you!

I did this at least 8 years ago and my muscles still remember what they learned.

The whole point is to increase explosive power, critical for technical climbing especially.

Here's what you do:

Use the heaviest weights you can.
Each set is 4 reps.
Do 6 sets.
Use free weights if you can.

The exercises:
Bench press
Squats
Good mornings (1/2 a dead lift)
One other exercise set: biceps/triceps, lats/chest, etc

And do at least 40 reps of calf raises each set.

Do this for about 6 weeks, then return to your normal, or some other type of weight workout. You should notice a huge difference - and you should be able to do heavier weights on your regular weight workouts too.

It really worked for me. Hopefully something like this works for you too!
