High intensity

In contrast, it seems that the volume is low (1-2 km per training session), with short episodes (4-10 min) of high intensity interval training or speed interval training (SIT), especially when they incorporate cycling, they have a lesser negative effect on the adaptations induced by resistance training through a concurrent program.

In addition, after or SIT training, the activation of PGC-1 increases to a greater extent than after long-term resistance training adapted to work, which leads to mitochondrial biogenesis. https://foodsocietyx.com
