Like the title says what would you guys recommend to spare muscle as you shed the fat during fasted steady state cardio (60-70% MHR)? I am using ON powder BCAA's and the serving size is 1 tsp which equals 5g total (2.5g Leucine but I forget the other two aminos amounts). Should I double up (to 10g total) or is this overkill? I also have a cup of black coffee, in order to get some cafeine in my system. Not trying to over think this, just curious as your opinions.
