Can you HIIT Like a Girl? @fitnessblender (22 min)

I've done this workout before, but wanted  a 20 minute workout this morning and figured I'd put on the heart rate monitor and put it on the list.

It's intervals, 20 seconds on and 10 seconds rest in between. That might sound like lots of rest, but you work hard during those 20 seconds and they want you to max out your effort.

It does have quite a bit of jumping, so it can be rough on the knees. It needs no equipment. There is no warm-up or cool down included, so you have to do that part on your own.

I recommend it! Good workout and quick!
