I just finished a weight training class in school and started to love being in shape. It makes me feel great and healthy. I signed up for a Team Sports class as an easy class for senior year and it turned out to be a weight lifting class. We did, Front & Back Military Press, Bench Press, Squat, Power Clean, Dead Lift, Hang Clean, Leg Press, Power Runner, Calf Raises, Step Ups, Leg Extensions, Incline Press, Hammer Curls, etc Anyways.. when I started to run again.. the part circled in the picture is the part that really hurts. It hurts so much that I have to stop and hobble my way back home. My friend says my tendon is messed up and I should just rest it a bit. I did that but it didn't help a bit. I hope you guys might know more about my problem and how to fix it. And about the walking. My mother says that walking can make you lose weight, but what i see is that she occasionally walks and does it really slowly. Do you guys have any advice for my mom?
