You don't need a machine,

A fitness instructor taught me,

Eat 20 machine eggs and 5 Jin of beef every day. Of course, the pickling is not good.

In addition, sit-ups are divided into 10 times every day. Take a rest when you are tired, and then continue when your physical strength is restored.

There is also doing push-ups, which is the same amount.

Finally, squat jump, the method is to squat first and then jump up.

The above figures are all based on 20,

The most important thing is persistence, hehe,
