Performing high-intensity intervals before Zone 2 training can lead to hormonal responses, high lactate levels, and inhibit lipolysis.

“because you start having all these hormonal responses and also you see you have high lactate levels in the blood and what we know very well is like lactate inhibits lipolysis so if you have a high interval in the middle or the beginning and you don't clear lactate very well you might have high lactate levels for a while and it's going to inhibit Li policies right also another study we have under review lactate um the autocrine level yeah decreases the activity of cpt1 and cpt2 so interferes with the transport of um of fatty acids as well”
