Volume vs intensity responders?

Training
2

It’s a good question, and lately I’m noticing folks favoring a more traditional high volume z2 base vs sweet spot. While I don’t disagree with z2 base training, I personally don’t know how much I’d get out of it if I were limited to 10-12hrs per week. So for me, I like the intensity of SSB and a reasonably good volume around 10hrs. I’d love to do a high volume z2 base to compare to myself though!
