Jake, hi there and sorry for the confusion

When I referred to more cardio being 'too much' I was referring specifically to the BFL 20 Minute Aerobic Solution (20 MAS). This has to do with the type of cardio it entails. High Intensity Interval Training (HIIT) can be muscle wasting if you do too much while not eating adequate protein (approx 1g per lb of body weight). Doing moderate intensity cardio does not pose the same problem. HIIT is anaerobic while moderate intensity cardio is not.

Cardio every day - so long as it's not of the HIIT type shouldn't be a problem. If you do notice that you start to feel tired or sluggish I would look to your food and ensure you are getting enough protein.
