Good on you for still having that mental fortitude for interval training. I did some recently and ended up cursing up a storm upon finishingnaturelover wrote: ↑Fri Feb 14, 2020 11:46 amIt seems to be I have the mental fortitude to push through an intense interval training or heavy singles in weightlifting but the kind of sustained endurance for ultra marathons is fascinating to me.
But then again I'm a bundle of fast switch muscle fibers so everyone is better at different things.
Fortunately with enough training most people can do some amazing things. Funny thing about those fast twitch muscle fibers (either Type IIa or Type IIX) with proper training they can act and resemble slow twitch muscle fibers ability to resist fatigue. So you'd be able to maintain both the explosiveness of fast twitch muscle fibers while maintaining the ability to 'last' during a race. Takes a while for the adaptation to occur but if you ever wanted to try endurance racing, it wouldn't be out of reach
