It's important to note that these power levels represent real world capabilities, which means that the durations above are not hard and fast rules. \u00a0Certainly, there are times when athletes can push beyond the normal ranges due to various motivations, ability to suffer etc. \u00a0Some athletes excel in different areas more than others through genetic variance alone. \u00a0Some are able to train their weaknesses to match their strengths. \u00a0Sometimes, though, it is simply not worth battling to build one skill if you have little to no genetic talent for it. \u00a0You may simply try to minimize the depth of your weakness in that particular area.<\/p>\n

It's also important to note that there is no absolute delineation between power systems. As you surpass the effort of FTP and cross into VO2 max, remember that it's not like flipping a switch. \u00a0FTP and VO2 max zones blend into each other as you move up the scale. \u00a0All these systems work synergistically in assisting each other, which means that training one often has an effect on another. \u00a0For example, training VO2max will increase FTP. \u00a0Increasing FTP will increase Tempo output. And so on and so forth.<\/p>\n
