You guys got any tips or specific exercises I can do to help build my endurance in my arms?
I’m only able to climb 1 day a week right now and it’s really frustrating when I’m trying to get some work done when my biceps and forearms start cramping up on me.

2 days a week I’m sitting at the house watching the kids and I’m sure there’s something I could be doing to help this. I was thinking of getting one of those little things you squeeze? Or resistance bands? Or maybe some small dumbbells? I imagine this is more of an endurance thing vs a strength thing. Any advice will be greatly appreciated. Ideally I would just climb more but unfortunately that’s not in the cards right now.
 
Anything and everything.


You can buy a grip exerciser set inexpensively.

A rubber band on the fingers and thumb is an extensor exercise.

Pull ups and hanging.

Stretching.


Hydration and electrolytes.
 
I take magnesium glycinate, not specifically for cramping, but it's a probable aid there as well.

Most of the cramping problems I had climbing were in the hot months.

Is it possible with you being green that you're overexerting compared to what's required? Typically when I start something new and risky I know I carry a lot of stress in my muscles that isn't required and fatigues me all the same.
 
What everyone else said, plus dynamic stretches and yoga. I'll keep whipping the draft horse of flexibility and core strength.

Also, a well muscled spinal column is far less prone to injury.
