If it is a fat-reducing period, you can arrange resistance training (it is best to repeat joint movements, such as squat, hard pull and bench press) under the condition of ensuring calorie deficit (this is more important than anything else). , but you must pay attention to safety, you can't lose weight and gain muscle if your hand is broken) and aerobic training for more than 40 minutes 1~2 times.
