@mohitraletta I’d highly suggest an arm day with isolation only exercises. Db curls, db hammer curls, preacher curl machine, long tops pushdown, long rope overhead tricep extension
@mohitraletta I had the same concern as a fellow skinnyfat, have you considered PPL X Arnold? I very recently swapped so can't speak about the results yet, but I am loving the extra arm volume
There are a few 4 day programs in there if you can't do more. Apollonian Physique, Greek God Revamped and Guts program are three off the top of my head.
