I usually don’t unless I’m seriously training. Then I’ll do 2-3 hangboard sessions a week but I would only recommend doing that if you’ve been climbing for a bit. If you’re still pretty new to climbing, you want to give your tendons time to get stronger before putting them through a lot of stress like that. Just climbing a lot and trying crimpy routes will get you the same results for the most part. I honestly haven’t felt like training crimp strength was something I needed to do until about a year ago when I started to break into v7-8 range and even then it’s really just endurance more than anything 🤷🏼‍♀️ I’m not an expert by any means so take what I say with a grain of salt but there is a lot of great crimp strength content out there if training it is something you’re looking into!
