I am approximately 40 pounds overweight.I am 5'8 and weigh around 180.My ideal weight is around 140-145. I love fast walking,and try to get 35 minutes of that daily.I am willing to lift weight,do sit ups,crunches etc.I also own a stair stepper.Can anyone help me plan an hour long workout that I can do every day that will help me lose the most weight,and keep it off.I cannot afford a gym,and running hurts my shins,I can jog some.Helpful,knowledgable answers only please.GODbless
