You should buy whey protein powder.
I practiced a lot. Men should not do high-intensity aerobic training every day, which will lead to the loss of protein, lower basal metabolic rate and inhibit hormone secretion.
I suggest you join the equipment exercise and pay attention to the exercise of large muscle groups, such as squat and hard pull. These actions stimulate hormone secretion, and the variable speed running is reduced to less than 30 minutes.
