What does 3x 8-10 reps mean?
A simple question. When a program suggests that I do an exercise 3x 8-10 reps, does that mean that I never move out of that reprange or does that mean that the first set should be 8-10 reps? As I see it it could mean one out of three things:
1. If I start an exercise with 10 reps and aim to get really tired from this set, the whole exercise will turn out something like: 10reps, 8reps, 6reps. This obviously mean that I stay with the same weight.
2. If I aim to remain within the 8-10 reprange throughout the entire exercise then the first set will feel fairly light and only the third set will be really pushing my limits. Again, staying with the same weight through the entire exercise.
3. If I want to get really tired from every set I and stay within 8-10 reps 3 times, I have to decrease the weight meaning that the first set gets heavy, the next set lighter and the third set really light.
So when someone writes 3x 8-10 reps, which is it that he/she means?
