i am on my third week of eca going to 4. i was doing some light jogging today about 70% of my heart rate. after jogging for about 2 miles, i found it no challenging at all. so i decided to step it up and run at about 85-90% of my heart rate for 2.5 more miles. i didn't get any sides at all and i did this about 2-3 hours after taking eca. can i just keep on doing this or is it really bad to run that fast? also since that eca has anti catabolic properties, is it alright to do cardio like that?
