After the workout is the absolute most crucial time to get some protein in. Morning and after workout are at the top of the list. Best thing to use post-workout is a shake, most of the time thats whats gonna carry the most protein and have enough amino acids etc to help absorb as much of the protein as possible. Try to shoot for at least 50-60g of protein post workout, because your body is gonna be starving for protein to aid muscle recovery.
