Do I need to do it at home at night to go to the gym during the day? There are dumbbells and abdominal muscles at home. I didn't go to the gym to do abdominal muscles for 8 minutes, but practiced chest muscles at home. . If you don't want to go to the gym, you can buy a set of TRX fitness equipment online, which is very suitable for fitness at home. It is a new trend of American fitness, and you can bid farewell to dumbbell fitness methods, and the training methods are very diverse. My husband just doesn't want to go to the gym to meet their gym coach. He learned this when he was studying at Dongyi Fitness School, so I bought him a set, which was very convenient. I suggest you buy one too.
