Treadmill intense for 20 minutes everyday. don't run on pavement you will get shin splints and you don't want them during your PT test. Mornings are the best time to workout to loss weight. Eat 5/6 small meals a day don't eat 2/3 large meals,large meals slow down you metabolism. Its a pain in the ass to eating 5/6 small meals but it works. Good Luck!!
