Under normal circumstances, you can't drink whole milk powder for fitness. First of all, full-fat milk has a high fat content and is not suitable for drinking during fitness. Because fitness is to reduce fat, it is necessary to control the intake of fat, so it is not recommended to drink whole milk powder. You can drink pure milk when you exercise. Pure milk is better than other kinds of milk, while milk with high calcium and low fat has low fat content and lacks many trace elements compared with pure milk, which is not conducive to fitness and muscle gain.
