For whey protein, you can try ON 100% WHEY, its the cheapest i can find and it tastes pretty damn good can get it at egonutritions and GNC

If your new to training, start incorporating few compound movements ex: Bench press, deadlifts, barbell rows, squats, chin-ups, pull-ups, dont use the machine for everything

yup but that is 5lbs, 10lbs is in a huge pack, cant find it any cheaper then that place
