This summer I am going to be rock climbing for 2 to 2.5 months. I will not be able to lift weights at all during this time. I was wondering what the best thing to do to try to somewhat keep my physique/strength, if anything at all. I was thinking a ton of pushups/vertical push ups and running many miles.
Also, at the place i know there is a pull up bar. I know i will use lots of upper body while actually climbing.
Another thing, how much will I have lost when i hit it back again at the gym in 2 months? thx
