Strength training: What are the benefits?

Cardio ou musculation meilleur pour la perte de poids



When it comes to weight loss, the debate between doing cardio and strength training may seem eternal. So, what is the best strategy? Does cardio burn more fat? Or does strength training offer a hidden advantage for sustainable weight loss?

In this article, we will break down the benefits and drawbacks of each approach and seek to determine which method is most effective for weight loss.

From a purely caloric perspective, intense cardiovascular training can often have the advantage.

A session of running or cycling can burn hundreds of calories in an hour, thus promoting a caloric deficit, which is essential for weight loss. Additionally, cardio helps improve cardiovascular health by strengthening the heart and improving blood circulation.

Let's take a concrete example: a 30-year-old woman weighing 70 kg could burn approximately 330 calories during a 30-minute run at a moderate pace. If she does this three times a week, she could burn about 990 additional calories, which could lead to significant weight loss over time, provided she also maintains a balanced diet.

However, cardio is not without its drawbacks.

It can be monotonous and repetitive, which can lead to a lack of motivation. Additionally, it can result in muscle loss if not accompanied by adequate resistance training.

On the other hand, strength training or weightlifting offers different but equally important benefits. Weightlifting stimulates muscle growth, which can increase your basal metabolic rate (the amount of energy your body burns at rest). So, while you may not burn as many calories during a weightlifting session as during a cardio session, you continue to burn calories at an accelerated rate for several hours afterward. This is known as the "afterburn" effect.

For example, if the same 70 kg individual mentioned earlier undergoes an intense one-hour weightlifting workout, she could burn about 220 calories during the training, but would continue to burn calories at an accelerated rate for several hours after. This effect can aid in weight loss, especially since the additional muscle gained through training can increase the individual's basal metabolic rate.

However, weightlifting also has its drawbacks. It can be intimidating for beginners, and without proper technique, there is a risk of injury. It is also worth noting that adding muscle can sometimes increase the weight on the scale, even if you are losing fat. In other words, you may be losing fat and gaining muscle!

So, which is better for weight loss, cardio or strength training?

The answer is that there is no "better" option. Both have benefits and drawbacks, and the best approach is often to combine the two. Doing cardio to burn calories and improve cardiovascular health, while incorporating strength training to build muscle and increase your basal metabolic rate, may be the best way to lose weight in a healthy and sustainable manner.

Ultimately, weight loss depends on creating a caloric deficit, and this can be accomplished in various ways. Whether you prefer cardio, strength training, or a combination of both, the key is to find a workout routine that you enjoy and can maintain long-term.

Remember that diet also plays a key role in weight loss. Whatever training method you choose, make sure to complement it with a healthy and balanced diet. Together, these elements can help you achieve your weight loss goals.

In conclusion, cardio or strength training, choose the option that suits you best, or even better, combine them. Remember that consistency and perseverance are the keys to successful and sustainable weight loss.
