High Intensity Interval Training, Ideal Routine?
I'm thinking about incorporating sprints into my weekly training in addition to my 12 minute-per-week Body By Science routine, although I'm not exactly sure why...my primary goal is to lean out as quickly as possible.
So I'm curious:
1) Would there be unique benefits to adding hiit sprints throughout the week if already following a Body By Science routine?
2) Is there any reason to believe it would encourage quicker/more effective fat loss?
3) Is there an ideal Bulletproof hiit formula to follow? (i.e. 30 second sprint / 30 second recovery / 3-7 times per session / 3 sessions a week)
My main motivation is a few friends of mine who do one-hour sessions of indoor cycling class 3 times a week, and look ridiculously ripped, all while I have to watch them eat donuts every morning and then politely decline to stay Bulletproof and "healthier."
So I feel like I should probably consider some form of "Bulletproof Cardio" in addition to my Body By Science weight training.
Thanks in advance!
