I started with that program too, but I changed it a little.
Barbell rows are replaced by pull ups after the 15th session, because I was afraid of injuring my shoulder. Now I make barbell rows slow with little weight additionally and pull ups every workout (with counterweights)
Furthermore I added sets of dips, butterflies, barbell rows, barbell curls, kettle bell swings and TRX suspension core training.
How does this sound? Legit?
