In the past when I have watched the modern day professional Body Builders in interviews, I have noticed that the really big guys just seem to be out of breath. Now I do not take any gear or anything like that, but I am noticing that I am somewhat experiencing the same thing at times. Today I was out digging holes (the old fashioned way... with a shovel) and found myself to be a little more out of breath than what I believe I should be. Does anyone else have this occur or know what it is? I am currently around the 212-213lb mark and in my early 40's. My workouts are done with the "myo-reps" scheme and I felt this was enough of a cardio component, but maybe it isn't... I am not a big fan of cardio and just tend to avoid it like the plague, but am thinking I should probably ride a bike a couple of times a week. As posted in other discussions, I feel that adding a stack of weight (whether lean muscle or fat) can be a load on the body and maybe this is just it? I would say that I am relatively lean, but could lose about 8 - 10lbs. I think my sweet spot weight is about the 205lb mark. I am just curious on what people think or if anyone else has experienced similar. Thanks.
