Some quick context about me: 27 yo, 5'10'', ~190 lbs. Lifted fairly seriously in high school and college, entered the workforce and promptly got knocked out of my exercise routine. Finally picked up lifting again at the start of 2017, so I'm about 6 months in at this point. After about 5 years off from lifting, I'm considering myself a beginner, and trying to train like a beginner - 3-4 days/week of full-body training sessions, focusing on building a strength base before tackling hypertrophy and fat loss.
My problem is that I'm starting to notice my grip is a limiting factor on deadlifts and pullups - I know my posterior chain and lats can handle more, but my hands are just plain giving out. I've always been told that beginners should avoid isolation work and focus on the big lifts, so I haven't done anything major targeted at the forearms. And my grip is getting stronger over time - it's just not keeping up with strength gains in the rest of my body, and I hate the feeling that other parts of the workout are suffering because my grip can't keep up.
Did anybody else have this problem? Is this normal, and I should just suck it up for now? Or would some grip training (farmer's walks, hangs from pullup bars, etc.) be helpful? If so, how would you program it?
Thanks in advance.
