I need to lose some weight...I need some tips! Please help?

If you need to work back up, intervals are your best bet. Jog at about medium exertion, then sprint. At first it'll be a jog of 3 minutes, then sprint of 30-45 seconds. When you can jog 1 min, spring 1 min, then start just running for 20 - 30 min at a time 3-6 days a week. When you start running for exercise it should be at about 13-14 on the exertion scale.
