From my eyes i look at it from a few points of view. Number one, if you do longer cardio like for 45 minutes then i wouldn't go to that 140 pulse range. I would keep it at 120-135 bpm. If you are doing different machines, some raise your heart rate alot faster than others so keep in mind the concept of muscle catabolism. Your body should not cross into the anerobic threshhold, because then your body will get it's energy from glycogen, and if that supply is used up then it will use amino acids as a secondary source. Amino acids are protein molecules, and protein is found in skeletal muscle, therefore your muscles will be next in line. So take home message is stay off the heavy hitting cardio if you want to preserve muscle while cutting. Also of note is that cardio will not, yes, NOT effect weights negatively. I did-and do 30 miles on my bike 4 times a week and when I started with that surplus of bike riding my squat jumped 30 lbs in the weight I was using. It also densified my legs like you wouldn't believe. Cardio also rejuventates the oxygen in muscles and wakes you up in the morning. It kick starts the metabolism and is good for your heart. Do the cardio, cause you can still gain while doing it. I'm living proof, and I'm natural. Also, If cardio affected weight training then in my football days we'd theoretically be weak pansies in the weight room. Ha, we were machines dude, we practiced in 100 degree heat with 20 lbs of gear on, and our cardio was
pure Hell! Take home message:
cardio will not negatively effect muscle gains. What will effect muscle gains is dieting. Dieting combined with cardio will cause muscle-loss but if you're diet is sound then I wouldn't worry about it too much. Also cardio in intervals is the best way to sap the fat stores and utilize lipid cells for energy.
