I figured it would be better than nothing on the days when I can't lace up my trainers and hit the pavement.
I've done it several times, and I can say with absolute authority that this 4 minutes routine kicks some serious tail.
And that's coming from a runner - I'm not claiming to be athlete of the year or anything, but my cardiovascular fitness is decent.
But I've also noticed that the routine gets easier each time, which motivates me to keep trying. Even if the real reason it gets easier is that I'm doing it slower...
Don't worry, I didn't know what a squat thrust or mountain climber was either. Mr. Google can help you with that.
So, do any of you actually try the things you pin? Do you use pinterest? I'm finding it to be extremely helpful for organizing the things I find on the internet, but it has also been fooling me into thinking I'm more creative than I actually am. Tricky, tricky. No, really, I'm having a great time trying the things I pin, and I encourage you to do the same.
