Hello, dumbbells are not very expensive. If you like them, what is money? I told you. Seriously.

You can take 5 to 10 Jin stool, which is a chair. It's harmless to the body, but there are some hand cocoons on my hands. This is to exercise arm strength, muscle strength, abdominal muscles and chest muscles. But just change your posture properly. Your finger strength is good. Landlord, I believe you will succeed.
