That walmart protein is crap imo. get optimum nutrition 100% whey or i take their nitro core 24 which is a blend. You might also lookinto getting a pre workout suplement my favorite is called Jack 3d by USP labs, also BSN NO-xpolde which i dont like but some people love it, or Gaspari Super pump 250 which is my second favorite.
