I believe in the LEAST amount of cardio necessary to get shredded, I think if you diet right and have the balls to grind through the low carb days then your golden.
I dont do more than 3 hard sessions a week. I'll do 2 high intensity days and 1 day slow and steady on the stairmaster or treadmill.
If your diets off then no amount of cardio no matter how hard will make up for that, You cant outrun a shitty diet.
