I just can't get comfortable with a hook grip or mixed grip.
I believe the issue is fatigue, since I'm able to complete the first few reps with a double overhand grip. I'm hoping that moving to phase 3 and deadlifting less frequently while training the chin-up will allow my grip strength to keep up. But if that doesn't end up happening, I'm going to try using straps for warm-ups and see if that helps. And as a last resort, I'll do work sets with straps. But I'd like to avoid that - I want to be able to open glued-shut pickle jars (a duty I signed up for when I got married).
Thanks! It's still totally surreal.
