Insist on doing 300 to 500 push-ups every day (pull-ups are also acceptable), and it is best to do push-ups with one hand ... As long as you insist, you can increase the muscles of your arms. ..

If you want leg muscles, keep running for half an hour to an hour every day. ..

Don't drink drinks and water while doing push-ups or running. Drink after running, drink slowly to quench your thirst. ..

Where there is a will, there is a way! I wish you success! ..
