HiiT
HiiT
It is absolutely legit. I am 8 weeks out from mv repair and started it two- weeks ago. Depends on what your goal is. I was very athletic before lifting, running, etc, but my runs were longer 4-6 miles range a few times a week. During my recovery phase, I obviously couldn't run that distance so I decided to practice HiiT. Then I began reading a few articles on how long, slow cardio (which I was the queen of) was literally making everyone fat (saw it on Good Morning America a few weeks ago) and burning off everyone's lean muscle. So I decided to do the walk/run thing at 30-60 second intervals for a half hour, then for the next 15 minutes of my workout, I added lots of football type agility drills (grapevines, mountain climbers, rope jumping) and wind sprints which wipe you out!
Its only been a few weeks, and truth be told, i don't need to lose any weight, but it is changing my shape big time and I'm preserving my muscle from lifting. In the 10+ yrs I've been working out like a fiend and have not gotten these results probably because of the 5+ days a weeks of hour cardio sesssions. Way too much time and very counterproductive, I've learned. Hiit really kicks butt. I am a little worried in that I'm only 8 weeks out, but I have no symptoms/issues and the dr did clear me at 4 weeks for full exercise, so I hope there are no problems going on inside!
