Programming vertical pulls and bicep isolations: how do you manage rest between sessions?
I run a two day split that I do 2-3 times a week (so 4-6 sessions per week, depending on my schedule and such). You can think of it as typical upper-lower split for this post's purposes.
I want my bicep isolation work to be on a different day than my vertical pulling (e.g., pull-ups) so that they don't interfere with each other as I find they tank the other's performance.
Because I put them on different days, it effectively means I'm hitting them every session, which can be up to 6x a week, albeit with fairly low per-session volume (3-5 sets of pull-ups on the day I do vertical pulls and 5 sets of bicep isolation on the day I do bicep isolations). On a weekly basis, that's 9-15 sets of pull-ups and 15 sets of bicep isolations.
I love my split and don't even mind this aspect of it. But I'm wondering if, based on your experience, and/or the current literature, this is too little rest between sessions for my biceps, even if weekly sets aren't egregiously high, or whether there are any other issues from trying out something similar yourself.
