Yesterday during my lunch hour I hit the gym to do something totally different. I walked on the treadmill. I intentionally kept the pace low but jacked up the incline, maxing out around 3.5mph with a 7.5-8 on the incline.
The aim here was to train within a certain heart rate zone – much lower than when I’m up in the orange and red during high intensity workouts like spin class. Training in this “fat burning” zone promotes the body to utilize stored fat as energy (hey, it is what it is,right?!) instead of burning through carbs. As you can see, I couldn’t help myself from cranking things up to boost my HR at the end of the workout. Equal parts low-HR guilt and glutton for punishment.
Training like this is the difference between hitting the gym to burn off that extra cookie you at at lunch versus all those extra cookies you’ve been eating at lunch for the past few years. I don’t entirely understand the science behind this (it’s likely as complex as we are) but I would certainly like to learn more about it.
If you look at the pic above versus the one from my ritual Saturday spin a few days ago, you’ll see that working on the treadmill yesterday dipped into my fat stores 39% versus 7% during spin class.
The moral of the story? Variety is not only the spice of life, but a key component to weight loss for fitness.
And I like spice. Especially chipotle.
