The more I read the scientific literature and based on the results I am gaining with my own body, I say do away with bulking and cutting. Now I am proposing this for everyone not on steroids and those who are not BB for competition although I would bet it would apply to the latter with alterations. Instead of wasting weeks of bulking and cutting, it would be more efficient to optimize the body to increase LBM and decrease FAT simultaneously and continuosly until the FAT has reached the desired %. After this point, it would be just a matter of maintianing within a given % fat levels and accepting a slower increase in LBM which is ineveitable the more one trains My justifications for this proposal are as follows. 1. As the body increase LBM which is a direct result of resistance training and proper nutrition, the body become more efficient at producing and more importantly maintaining LBM. Concurrently, fat utilization is also increased and thus lost. I see a cycling of bulking then cutting as upsetting what the body has learned to do which is reach a level of efficiency. 2. I have never done a bulk, cut or SD cycle and over the last year my strength has increased, my LBM has increased and my body fat % has slowely decreased. 3. This has been achieved my eating between 1-1.5% g protein per kg body weight with no supplementation other than creatine. I only use amino acids during bike races and afterwards and sometimes during and after very long cardio/bike training sessions. 4. The amount of fat gained during bulking is normally much more than the amount of muscle gained making the profit not really worth it as you must then do a cut to get ride of the fat which, as it is perscribed here, results also in a loss of muscle. a vicious circle. IT is becoming clear through the literature that it is much more economical to get good high quality protein, the best being milk, and getting the body to optimize LBM synthesis as a matter of routine and without cycles. There are an increasing number ofstudies showing that not only is milk the best source of protein, also you really only need a post exercise shot of 500 ml skim milk to get the most advantage of resistance training induced muscle synthesis. Other studies have shown that 10 g of Amino acids was enough and any more was just oxidized and not utilized for LBM synthesis. The day after the resistance exercise, considered as a rest time to allow the body to repair damage , protein requirements are not much higher than normal if at all. In other words, you don´t need more than the 1 - 1.5g per kg body weight and maybe even less. This is even more imprtant in that the habitually training persons body is even more efficient in using whta is given so much so that it may even be the case that one can take in even less protein to get even more growth. Couple this with the fact that the trained body is even more resistant to catabolism as the act of training, in and of itself, is anabolic and I arrive at the conclusion that we shoudl scrap Bulking, cycling and SD and do more cardio coupled with 3x weekly fullbody HST-5x5 strength training to achieve ultimate physical superiority. stick that in your hat!
