There's no need to add protein supplements
Save your money.
The majority of Americans get more protein than they need already. Getting it from quality sources is a good dietary goal to pursue, but think about all the herbivores in the animal world. Their bodies build muscle without protein shakes. Your body can, too.
Lift heavy, increase the weight progressively and get plenty of rest. Keep your cardio to 30 minute sessions. I'll bet you see muscular results without changing your diet much.
