text: if i have a pretty good diet & i'm not overweight to begin with, will walking on an inclined, manual treadmill for about a half an hour 5-6 days a week, tone up my body or cause me to lose any weight? looking a little flabby, but have a new schedule & am cut short on time..... sandra it is easy and fun. your best bet is to use that half hour to strengh train.start off light and get your technique down.go to a gym or get a strengh training book. in few short weeks you will be a expert and see results. do not over do it. you dont want to burn out,you want it to become a fun habit. good luck
