Generally speaking, if you are young, the effect of muscle training is not particularly obvious. In addition, don't just think about practicing a certain muscle, or you will be deformed in the future. And exercising this part of the body muscle will also have an effect on the growth of other muscles. So I suggest you practice your whole body in a planned way, and don't just focus on one part.

If you want to develop muscle volume and strength quickly, you have to rely on big weight. In other words, the weight you use can make you only make 7-8 pieces in a group, so you have no strength. If the weights used are too light, you can make 30 at a time, which is not very effective.

So doing push-ups, one group only does 8 to 12, and the effect is not very obvious. You can do parallel bars arm flexion and extension exercises first, and then do push-ups.

If your parallel bars are not strong enough, you have to do push-ups first. You can do four groups, each group requires all your strength, but you have no strength at all, and the last group can't.

Regarding the exercise of abdominal muscles, you can search for the video of "eight minutes of abdominal muscle exercise" on the Internet. It only takes eight minutes a day.

Finally, in any case, if you want to get bigger, it will be hard to exercise, and it is impossible to grow beautiful muscles easily in a short time.

Hold on!
