I decided to give HIIT a go this cycle but I never did it before and honestly I dont really know how to implement it.
I suppose I would just need some general guidance and practical advice...mmm actually I would need to know what I gotta do...
I heard about sprinting for a few seconds (how do you count seconds while sprinting?)and then walking for a few minutes but I dont know nothing more,anyway I suppose I cant do it at the gym.
