You Aren't Doing the Right Workouts to Lose Belly Fat
Following expert-approved recommendations to reduce belly fat (and body fat in general) and not seeing results is frustrating. As an NASM-certified trainer, I recommend reviewing what you're doing for exercise. Being active is great for your overall health and well-being, but in order to reduce belly/body fat, you should focus primarily on strength training and cardio.
Strength training is a great tool for losing body fat because it allows you to burn fat and build muscle simultaneously. Since muscle is more metabolically active than fat, the more muscle mass you have, the higher your resting metabolic rate (how many calories you need for processes that keep you alive like breathing and brain functions) becomes. Simply put, more muscle leads to burning more calories when your body is at rest.
I also recommend people add cardio to their weekly workout routine to burn fat. Too much steady-state cardio can cause you to burn fat and muscle, so you'll want to limit your cardio sessions to 30 minutes or less, Rondel King, MS, CSCS, exercise physiologist at NYU Langone's Sports Performance Centre, said in a previous interview.
