Those who decide to mix there cardio with their weight training within the same session, in an attempt to burn more calories or fat during the session itself. I urge you to change your ways.
Martin Berkhan has coined this “fuckarounditis”, my definition would be a misinterpretation of what’s important, which is maintaining strength during an energy deficit to preserve muscle tissue, the energy deficit at the end of the day is the most important factor.
I couldn’t care less how many calories/fat was burned during my weight training sessions, only if I was in a caloric deficit at the end of the day (assuming sufficient macro nutrients are in place).
Jumping, skipping, running, shadow boxing, set ups or whatever cardio you decide to do in between your weighted sets, is almost certainly going to mean less strength= less total poundage’s being used during the session itself & therefore if you continue this way, will equal muscle loss.
Keep your cardio & weight training separate with regards to maintaining muscle mass, perform your cardio at the end of your weight training or another time, if necessary.
Focus on what counts (maintaining strength & a chronic energy deficit) & ignore the perceived importance of more sweat, hard work in between your heavy weighted sets & how much fat/calories you burned during your weight training sessions.
Remember there no medals given for sweating more than the person next to you.
