Lately I’ve been seeing a very common mistake fitblrs are making with their heart rate monitors and calorie expenditure counts. They wear their HRM during an entire workout and then assume that the calories burned number is accurate. If your workout consists of pure cardio, then yes the number is relatively accurate. But what about strength training, or a combination of cardio and strength? The short answer is that the HRM calorie burn during any strength training exercise is NOT an accurate representation of how many calories you actually burned during that workout. So if you did 20 minutes of cardio and 50 minutes of lifting and your HRM spat out “1115 calories burned” I wouldn’t go and splurge on a bottle of peanut butter just yet!
In order to understand this I’ll first explain how HRMs count calories. First of all HRMs DO NOT measure calorie expenditure directly or even indirectly, they only measure your heart rate. Using that heart rate value HRMs estimate your calorie expenditure specifically for steady-state AEROBIC activity using a mathematical algorithm. The formula that is used is the relationship between heart rate and VO2 (oxygen) consumption plus other variables like sex, weight and age. This is a linear relationship that states as heart rate increases VO2 intake increases, and therefor the higher your heart rate the more calories you’ll burn per minute at a constant rate.
So if you’re jogging on the treadmill at 5.5mph for 10 minutes at a constant HR of 140BPM, your calorie expenditure will be roughly 100 calories.
But what about strength training? When you lift weights your heart rate jumps up and down all the time because you’re working in an ANAEROBIC state. Oxygen can’t get to your muscles in fast enough which spikes your heart rate to get blood and oxygen to those cells. So when your heart rate jumps up to 160BPM for a few seconds, this does not mean that you burned the same amount of calories lifting a single weight as you did when you’re using multiple muscle groups to run. The linear heart rate vs VO2 consumption relationship does not apply to weight lifting. Weight lifting has its post-workout benefits, but this isn’t something that can be measured accurately with a HRM.
Other factors can influence your heart rate AND HRM calories burned reading. If you’re stressed your heart rate will be elevated. If someone startles you your heart rate will be elevated. But none of these factors cause a significance increase in calories burned, but your heart rate monitor will perceive it as such and give you an inflated calorie burn!
Take a look at the situation logically even. Consider how much energy it takes to burn a measly 50 calories jogging. You have to jog for about a half a mile (or 5 minutes) at a consistent pace, stimulating so many core muscles in your body. You’re not engaging a single muscle group for 30 seconds and then resting for 2 minutes until your next set. Just because your heart rate is elevated during your weight lifting session, does not mean that you’re burning tons of calories while you sit there and rest. Yet this is how your HRM perceives it.
So that’s why you should really only rely on your HRM to estimate the number of calories you burned during cardio if that’s what you’re using it for. I hope this helps!
Objectively speaking, I would assume honey is the “healthier” sweetener for its nutrition properties and the fact you can eat it straight from the honey comb instead of processing it. Though, if you’re not using much sweetener in general then it’s pretty insignificant.
I’ve been feeling bummed for about a month now over something. So the other day I kind of halfheartedly prayed about it. It was a total fleeting moment. So you can see how it was to my surprise it actually happened. I didn’t even realize that my prayer request was answered until I got in my car and drove home. A lightbulb just came on in my head and I was like oh.. OHHH. lol. It’s such an amazing feeling though, and it makes me feel really blessed over something so trivial.
Thinking back on the situation that unfolded… gah. asfkdjhgkjdf. I don’t want to delve into the details but can I just say I was realllyyyy happy. And I feel like for the first time in a long time what I’m doing is right. It just feels right.
Eeep :3 Thank you ♥
I find it so hott when a man can cook!
Paleo is a concept of eating nutritionally dense whole foods, naturally (organic) grown with no use of chemicals or toxins, minimizing your intake of processed foods, industrial seed oils, and added refined sugars, anything artificial, GMOs, toxins, and foods that have a negative impact on your body (like anti-nutrient legumes and grains).
Paleo refers to the paleolithic era before the advent of mass agriculture (neolithic). People just ate more naturally, thrived better, and had less metabolic diseases that are common today.

Wow, that’s awesome! I hope you enjoyed it. :) There’s obviously no “right way” to study the Bible… at least in my personal opinion. I think you should flip through and find something that catches your eye. Then start in the beginning of that book and read it through to understand its context. I find the books in the New Testament are most applicable to my life and I can easily relate to those concepts (Corinthians, Galatians, etc). I also always enjoy rereading Revelations, Genesis, and sometimes the poetry books. OR if you’d prefer a more systematic way, you could always start from the beginning. I know there are lots of phone apps and websites online that can help you schedule and pace yourself. Hope this helps. :)
