Male athletes can choose a tire weight of 450 pounds (about 205 kilograms), and female athletes can choose 350 pounds (about 160 kilograms). The muscle strength and aerobic training effect brought by this weight are helpful to many sports competitions, such as baseball or volleyball.
Ordinary bodybuilders whose physical fitness is not the same as that of professional athletes can also carry out big tire training. The weight is about 200~300 kg (about 9 1~ 136 kg).
