Heat + Knee = Indoor Exercise Questions

HailDawgs

Hey MFPals,

I live in the South, and the heat is unbearable as some of you may unfortunately know. I am doing Couch 2 5K, and I have to run again tonight (to avoid the heat). My knee is starting to become more painful, so I wear a knee brace, but there is a problem.

During the day, I am sedentary; I go to the gym 3 times a week. With that sedentary time, I am not burning any fat.

Does anyone have any exercises I can do inside that will help me burn fat? Any programs or anything not intense on my knee and good for an overweight person?

Thank you!
