Throughout my training history, ive always done zone 5, 3-5 min intervals, 100% sitting. Today, i was doing them on a pitchy hill that made sense to sit and stand during the interval depending on the steeper pitches. Completely crushed them. They were still hard, no doubt, but power was more closer to the top of the zone.
Did i make the efforts easier by adding in some standing? Seemed like maybe.
What say you, should these interval be done 100% sitting? Or is mixing it up with some out of the saddle good too?
