If you dont compete, please state that in your responce. Ok so I am getting rediculously bored with my cardio routine, which has been 1 hr am empty tank tredmill 10% incline 3.5 mph and same in the eavnings 1 hr pm same routine. So tonight I decided to liven things up a bit. I went out and hit one of the popular walking/ jogging spots that every town has, it contains some hills here and there but is mostly flat. So here is what I did I walked one block jogged one block for over 5 miles, then a half lap around the track with a set of stairs halfway through. Now the question is, I am 4 weeks out should I even be jogging? Am I better off just sticking to my old tried and true tredmill routine. Both consisted of an hour btw. Also I like crystal light. Question is can it cause an insulin spike I usually only eat it with my post workout bedtimish meal which is about a lb of lean meat. All answers are appritiated.
