Hate to say it, but vanity is playing a large part in selection here.
Aesthetically speaking, chin-ups are more beneficial right?
Just wondering why pullups are generally favoured over chins?
How many simple fitters switch in chins instead of pullups?
Anyhow, would be nice to hear some reassurances from SF veterans..
Do pull-ups actually build bicep mass over the course of simplefit program? (I do understand that biceps are not engaged as much during pull-ups... but, are they engaged sufficiently for growth/strength?)
