Why You Should Stop Counting Calories Burned During Strength Training
It’s the last Friday before my kids head back to school, and I can’t believe how quickly summer has flown by. Like many parents, I’m not ready to let it go-but I am ready to share a really important conversation I had with a friend this week.
She asked me a question I hear all the time:
“How many calories should I be burning when I strength train?”
She went on to explain that some of her friends told her, “If you’re not burning at least 300 calories during an hour of strength training, you’re wasting your time.”
I stopped her right there. And here’s why.
The Purpose of Strength Training Isn’t Calories Burned
When you strength train, you’re not doing it for the immediate calorie burn. Read that again: the purpose of strength training is not to torch calories during the workout itself.
The real goal of lifting weights is to build muscle and strength. This matters because when you’re in a calorie deficit to lose body fat, your body doesn’t just decide to burn fat-it will also break down muscle if you don’t protect it. Strength training ensures you hold onto lean muscle while your body taps into fat stores for energy.
That’s the key difference. Fat loss comes from a calorie deficit. Muscle preservation and body recomposition come from strength training.
Why Strength Training Beats Endless Cardio
Too many people obsess over their smartwatch or fitness tracker, checking how many calories they burned in spin class, bootcamp, or OrangeTheory. But the truth is, those numbers don’t matter nearly as much as you think.
Cardio burns calories in the moment. Strength training changes your body long-term by:
Building lean muscle, which boosts your metabolism.
Making you stronger, so everyday life feels easier.
Helping you look toned and fit, not just smaller.
The Takeaway
If you want to lose body fat and actually change the way your body looks and feels, stop worrying about the calorie count on your watch. Instead, focus on creating a sustainable calorie deficit through nutrition while using strength training to maintain muscle, get stronger, and reshape your body.
So please-don’t waste time debating calorie burn numbers with your friends. Use strength training for its true purpose: to make you strong, confident, and unstoppable.
