If you are willing to endure hardships and are not afraid of fatigue for leg training, then buy a sandbag vest and sandbag leggings, as well as sandbag arm strength. Run five or eight kilometers every day and kick in groups. If you are energetic, continue to run several groups 100 meters, leapfrog. You must have a fitness center there, doing push-ups, horizontal bars and parallel bars. That can basically replace sandbags, and if you persevere and never give up, you will go on for a long time, that is, as light as a swallow, flying over the eaves and climbing the wall, referring to the speed and flexibility of climbing mountains and the jumping ability of running, so you must practice fast impact! In order to succeed. You will be a great person in the future! Wish you success in advance. Hang sandbags so you don't have to think about bungalows. If you want to hang it, you can hang it on the building, which is a bit troublesome. If you are practicing boxing and palm manipulation, I suggest you buy a tumbler and turn it around every day, just like eight diagrams. You can also choose hard work such as iron sand palm and inserting sand every day, which is the fine sand we usually see. Sand quantity from less to more, from soft to hard! I wish you become the elite of China! National hero! Come on!
