You can do some push-ups in bed every day to exercise your arm muscles. I just don't have the conditions to go to the gym. To put it bluntly, I have no chance to go to the gym, but I especially like muscles and fitness. So since I came up with this idea in senior one, I have been doing some push-ups in bed every night after studying by myself. You can only do ten at first, but after a long time, it will increase to twenty, fifty and one hundred. I can exercise my arm strength in bed in my spare time.

You can also use flat support to exercise abdominal muscles. All training without going to the gym requires perseverance, and it takes some time to stick to it every day. Flat support can not only exercise your abdominal muscles, but also exercise your arm muscles. If you can, you can also run outdoors to increase your thigh muscles. The longer you keep running, the more thigh muscles you have, and the stronger your explosive power will be. However, all these require long-term persistence to achieve results.
