Fitness can be divided into several systems, and choosing different systems should consider what the fitness goal is. Most people will give priority to a treadmill with parallel bars function, which is convenient for aerobic fat-reducing exercise and simple strength training. If you want to develop strength or muscle circumference, a set of combined dumbbells is almost necessary (even better if you have a barbell bar). For women, yoga mats are usually the place where training begins. However, gymnastics, TRX, CROSSFIT, HIIT and other training systems have different preferences for equipment. For these trainings, novices must find professional instructors, so they can be done directly by teachers. Of course, if you are doing prisoner fitness (self-esteem training), all you want is a space.

On the other hand, if there is nothing to pay attention to, it is actually the combination principle of aerobic+anaerobic, upper body exercise+middle+lower (front+rear).
