I understand that part. But what I'm NOT clear on is this. . .
1. The way to go, as I understand it, is SE1, SE2 (or vice versa), then last is Speed Endurance. But if that's the case then you are going Lactic Power first (SE1 and 2), and then Lactic Tolerance (Speed Endurance). I thought you build lactic tolerance first, THEN lactic power?
2. And here's another question. If you can get the same Lactic Tolerance effect with 85-90%, then what would be the purpose of upping the intensity to 90-95 (or more) percent?
