cardio on treadmill make you loose leg muscle?

[shreds9]

I want to keep all my leg muscles and strength. If I were to do cardio in the mornings for 45 min, would I loose anything in my legs? By the way I'm doing a high incline if that makes a difference. (2 times a week cardio).

Empty stomach?

45 minutes seems like a pretty long time for fasted AM cardio -- I get the idea the body might go into a pretty catabolic state with that duration. I would rather see you do 4 sessions per week at 22.5 minutes each instead.

Too much cardio gives me stick legs quickly.

I do 15-20 minutes of light biking before the work outs.
Any more ... and I start dropping.

Agreed. Either eat something first, or spread it out later in the day.
