We discuss everything sweetspot. How do we define it, what kind of training is it, what's the nature of progression, how much is too much, upsides and downsides including time efficiency, fueling, over/unders, and more. We also answer tons of listener questions, like if it can raise FTP, if it's overrated or underrated, sweetspot for sprinters, how long you can hold it relative to your FTP, and much, much more.
