Ian King has mentioned that beginners benefit from higher reps (8-12). I am going to try to prove why I may benefit from low reps (4-8) despite the fact that I am a beginner. First of all, King has also mentioned that the way your muscle fibers act (regardless of what fiber type they are) has a lot to do with your training history, more specifically, your training history during your formative years. Well, I am only 17 and I am a beginner but because I am in my formative years it would be of benefit for me to perform low reps. The reason being of course to make my fibers act more fast-twitch. Also when I perform main lifts at 80% of my max for that lift, I can only do 2 reps. This has nothing to do with age because I know a 14 year old beginner with absolutely zero training history who can perform 20 reps at 80% of his one-rep max, a 16 year old beginner with some training history who can perform 11 reps at 80% of his one-rep max, and a 17 year old intermediate with years of training history who can perform 7 reps at 80% of his one-rep max. I myself have trained on and off for the last two years. But anyways, this is another reason why I should be concerned doing high reps, because for me to do high reps I have to use LOW intensity, maybe far less than 50% of my one-rep max. So again, it would be of benefit for me to work out in the 4-8 rep range regardless of the fact that I am a beginner. In addition, Dr. Hatfield wrote that anybody who performs less than 11 reps at 80% max at a lift is predominantly fast-twitch for that lift (the main logic here is that fast-twitch muscle have a low oxidative capacity and thus lacks endurance). Well, I performed exactly two reps at 80% of my max for squats, bench, rows, and curls! Dr. Hatfield went on to write that for someone who performs low reps at 80% of his or her one-rep, it would be most beneficial to perform 4-8 reps.
So, despite the fact that Ian King has said that beginners benefit from higher reps, I have made a case proving that this doesn’t apply to me. Actually, I’m not sure (otherwise I wouldn’t be writing this post) so please let me know if you think I’m right or wrong. I myself don’t know if I’m right, so this is why I would appreciate anybody to let me know what you think. Thank you for your time!
