What is a better alternative for burning more calories during workouts instead of using weights?

The choice of increasing workout duration as a means of burning more calories during workouts is indeed a viable strategy. When the duration of a workout is extended, individuals have the opportunity to engage in physical activity for a longer period, which can lead to a greater overall calorie expenditure. This is particularly true in cardiovascular workouts, where maintaining an elevated heart rate for a longer time translates to more calories burned.

While incorporating more intense exercises can also significantly boost calorie burning in shorter periods, the context of the question suggests looking for an alternative that focuses specifically on duration rather than intensity. Longer workout sessions can facilitate endurance training and can be particularly effective for those at different fitness levels who may be more comfortable with gradually increasing the length of their workouts.

Taking breaks between exercises can lead to decreased overall workout intensity and duration, hence resulting in fewer calories burned. On the other hand, focusing solely on calorie restriction does not enhance workout efficiency or the calorie burn that comes from physical activity, as it limits the contribution of exercise to overall weight management and health. Therefore, the choice of increasing workout duration stands as an effective alternative for calorie burning in workouts.
