All too often I’ll hear people say things like “Well, I’m just trying to lose weight. So I’m only doing cardio and not doing any weights.”
This is not an ideal strategy. Most likely, if you’re trying to lose ‘weight’, what you’re REALLY trying to lose is fat. All weight loss requires a calorie deficit (which is why cardio can be really helpful for that cause), but a calorie deficit really doesn’t give a damn about how you want to look. It’s just going to start burning things up – a little bit of fat here, little bit of muscle there…
This is one of the main reasons resistance training is important during fat loss. In a calorie deficit, resistance training will help preserve your muscle. So as you lose weight, you lose more fat and keep your muscle. That means you won’t just shrink down, but will also help at reshaping yourself by more significantly impacting body fat percentage.
And although not a HUGE deal, but probably significant in the long term, for every pound of muscle lost, you burn 5 less calories per day (compared to only 2 calories per pound of fat)
So if you’re in a calorie deficit and losing weight (or trying to), doing some resistance training is definitely in your best interest.
