Barehanded, always.
I have never used gloves or straps.
While both of these have their part/place.... IMO, they are not needed.
I chalk up on heavy deadlifts. For heavy shrugs, i just use the smith machine b/c anything over 100 pound DB's really digs into my palms BAD. pain = i focus on that instead of form.. and we can't have that.
i have a few calluses on each hand (hot stuff i know

)... but the rest of my hands are soft. it's right at the top of my palm where the rough calluses are.
I have a feeling that gloves would mess me up anyways. 7 years of bodybuilding with no gloves.. no point in downgrading now, it's a habit.
