Interval Yo Butt Off!!!

SN: I like the title of this article, so I'm going to keep it, but...having butt is the new black, so don't take that literally-lol- moving along (this is so off topic).

This week, I took a chill from the P90x...okay, not a chill, more like a full sabbatical (from certain DVDs). I've become slightly bored from the repetitiveness of the DVDs. I'm not sure what's wrong - I've done the same kind of thing at the gym for months at a times and I've had no issue with it. I've done 3 P90x (one is the abs) routines this week in between my days of walking (5 days BABY, YESSSS!!!). However, in my haste to find a quick fix to jazz up my routines, I've been "lead to the water" by friends a research to interval training.

I've taken my walks to a new level this week by adding light jogging and squats. These burst of energy will boost my endurance and my body's potential to burn fat. In track terms, I've been walking the "straights" and jogging the "curves" ...or is it the other way around -anywho, you get the gist.
According to the article in the New York Times:

After interval training, the amount of fat burned in an hour of continuous moderate cycling increased by 36 percent, said Jason L. Talanian, the lead author of the study and an exercise scientist at the University of Guelph in Ontario. Cardiovascular fitness — the ability of heart and lungs to supply oxygen to working muscles — improved by 13 percent.

Check out these videos I jacked (lol) from YouTube below.... (I know she's a little cheesy, but aren't most trainers? Besides, I love how she makes it fun, so view all her videos on YouTube. This is interval walking, but intervals can be applied across training routines. Interval walking is cool because you can add whatever burst of energy you like to your routines). Between walking the straights and jogging, I'd do a minute of squats...very cool stuff.
