Hey I think for for a serious BB and or PL they need to save that energy for their lifting for the most part. I always needed ALL my energy because i was lifting heavy with going beyond failure. This just feeling like i cant do another set , total burning still from set to set.
So what would do was go straight in a little stretch and begin lifting. Then after workout would come get on the bike or cardio machine and get to cardio.
SO get the gist of this , I'm a skinny Ecto... never had a problem with fat tissue , hence i didn't do much cardio. I was all abut MM . I suggest go you go by what you your goal is at this time. Try both ways, one week at a time..
Good Luck
OMM
