I just stared working about a month ago, and I been looking at cardio routines, is HIIT a good option?. I am not very clear on what is involve, but it seems that is doing intensive card of X amount of time.
If any body can explain this HIIT concept I will appreciate it very much,
Yes, there's nothing wrong w/ beginners doing HIIT.
