I’m trying to incorporate polarized training to work on my endurance. I do high-intensity work at the gym as they have POWER MAX (maybe only common in Japan? It’s a stationary bike specially made for HIIT). Would it hurt if I do some of my low-intensity work before and after my HIIT sessions? Should I separate them and have “high intensity days” and “low intensity days”? I’ve only found researches on polarized training that were carried out with separated days for two intensities.
I thought it shouldn’t hurt as long as I can work hard enough for HIIT.
