I have been using a training program with extreme intensity in the rep range of 6 reps, I have heard this is the best for slow twitch recruitement and gains the best in strength thus the best in size. In the past I have used 3-6 warm up sets one work set to failure, then usualy a follow up set to develope a pump with a lighter weight and slightly different exercize. I find half deads and pull ups(for back) dips( for chest) and squats produce the best results for my growth. Do back on one day then legs a nd chest the other alternating lifting 3-4 days a week (ie. I feel I haven't recovered over the weekend much or don't get enough sleep I skip a day so my body can recover. Now, I have heard that working with a 12-16 rep range would help me out more and using a rest stop method instead of doing a follow up set would be more efficient and cause better growth by better muscle fiber recruitement. I have been working with the same weight for some time and I got my reps up to 8-10 but I find myself loosing breath and just feeling too spent to push it up even though my muscles feel like they could do a couple more. This happens especialy with squats and if I ever do dead from the floor I can forget about going past 6 reps no matter what the weight is. Could this be because I have trained in the 6 rep range for a couple years I'm now just set in a mold? I would like some feedback from people how they went from a low rep to higher rep range if they had any problems. I also have been practicing extreme streching and finds it makes sure I don't have any knee problems and I recouperate faster. Thanks for any input!
