Cardio is Bullshit

[greatshape]

i walk for 30-50mins after my weights training in the am, and 60mins in the am on non-weight training days.
Im a female w a bf of 21% wanting to get down to 18%.
Is this a good plan?
I weight train 4xp/w and cardio 6xp/w.
I have a clean diet. What kind of diet would you guys recommend for me. I feel 'stuck'!

You'll have better results cycling at heart rate +/- 70% of MHR.Do it at least 4 times a week for 30-45min.You'll love the result!
