As a means of enhancing muscular strength, weightlifting—also known as resistance training—has been practiced for centuries. Body weight, resistance bands, machines, dumbbells, or free weights—resistance training helps us build strength, increase muscle size, and combat age-related muscle loss, according to research.
All the more so as of late, it's become famous among those hoping to get thinner. Running and cycling, which are both effective at reducing body fat, can also reduce muscle size, resulting in weaker muscles and a greater perception of weight loss because muscle is denser than fat. However, in contrast to endurance exercises, there is evidence that resistance training not only helps reduce body fat but also increases muscle size and strength
The After Burn Effect
Our muscles require more energy when we exercise than when we rest. Our muscles use oxygen to help them break down fat and carbohydrates stored in muscle, liver, and fat tissue into usable energy. As a result, when we exercise, our breathing becomes faster and our hearts work harder to deliver more oxygen, fat, and carbs to our exercising muscles.

The kind, length, and intensity of the exercise, as well as the fitness level and diet, determine the extent and duration of the after burn effect. The after burn is stronger and lasts for a longer time when you exercise for a longer period of time and use multiple large muscles.
The best ways to increase both short-term and long-term after burn are high-intensity resistance training and high-intensity interval training (HIIT). Due to HIIT's increased fatigue, it is believed that HIIT-type exercises are more effective than steady-state endurance exercises. Because of this fatigue, more oxygen and energy are needed to repair damaged muscle and replenish depleted energy stores over a longer period of time. Due to the "after-burn effect" and the high calorie cost of the training session, resistance exercise is an effective way to lose weight
Long Term Fat Loss
Long-term weight management can also benefit from resistance training. This is due to the fact that muscle mass has a significant impact on resting metabolic rate (RMR), or how many calories your body needs to function at rest. Fat is the body's preferred energy source at rest, and the resting metabolic rate accounts for 60–75% of total energy expenditure in non-exercising individuals.
Through resistance training, muscle size increases, which in turn increases or maintains fat loss over time. According to a review of 18 studies, resistance training increased the resting metabolic rate more effectively than aerobic exercise or combined aerobic and resistance exercise. However, in order to maintain fat loss and lose weight, calorie control is also essential.
Exercises for resistance training should involve two or more joints, work the entire body while standing, and target the largest muscle groups. All of these make the body work harder, increasing muscle mass and, consequently, RMR. Intensity, volume (the number of exercises and sets), and progression (increasing both as you get stronger) should all be part of an effective resistance training program. During your workout, the intensity should be high enough to challenge you.
The repetition maximum method is the most efficient approach. For fat loss, this should be anywhere from six to ten repetitions of an exercise with enough resistance to exhaust you to the point where you can't comfortably do another full repetition. It is recommended to perform three to four sets for each muscle group twice or three times per week.
The repetition maximum method also ensures progression because, by the tenth repetition, you'll need to increase resistance or load even more to exhaustion than you did the first time. By increasing the resistance or intensity so that fatigue occurs after performing fewer repetitions, such as eight or six, progression can be achieved.
By increasing the amount of calories burned after exercise and by increasing muscle size, resistance training aids in the reduction of excess fat. Joining it with a sound eating regimen will just further increase the deficiency of overabundance of muscle versus fat and may likewise give other positive medical advantages
