How important is Cardio ? And how often should it be done ? Right now I do it two times a week.
* Help on Weightloss HIIT vs LISS
* Cardio and fat loss
The importance of cardio for anyone is up to each said individual. The optimal frequency and type of cardio performed is also an individual preference, as everyone should use what works best for THEM.
great for cardiovascular health if thats important to you
from what i remember from class, doing 30 min of cardio 5x a week can lower resting heart rate 1 beat per min per week for the first 6-7 weeks
