Recently I have came into a discussion with an individual who is training to become a personal trainer. We were talking about reps and they made a statement that seemed idiotic to me, but I actually want to explore the validity behind it. Here is what they said:
"Higher reps (8 to 10) lead to toning, while lower reps (4-6) lead to bulking. By doing sets of 5 you are bulking."
Now, I could care less about "toning" or "bulking" but the general statement irked me and I wanted to refute it.
Do the number repetitions within your set legitimately change body composition in some way? I call bull. In my very limited knowledge and understanding- it seems as if the only thing that would lead to "toning" (I presume lose of body fat) and "bulking" (I presume muscle gain) is more related to nutrition.
