How many repetitions should the weights be for burning fat in resistance training?

Question

At the same time, I am doing aerobic exercise on the treadmill and taking a diet. My trainer told me to lift light weights of 2 to 5 kilos so that my skin does not become loose. Please guide me on how many repetitions and how many sets should I practice.

Answer 1

For exercises that want to have a good effect on skin and fat, we recommend exercises with repetitions above 12 and below 25 and with very light weight and in 1 to 3 sets. In the first weeks, practice one set and gradually up to 3 sets per movement.
Circuit training is the best system for us
