What should I do if my chest becomes a little sharp after practicing push-ups?

Practice flying birds or crossing. Push-ups are very close to bench presses. Originally, the bird and cross were linked to prevent the chest muscle gap from expanding too much after bench press. You can also contact them now. Cross usually has exercise equipment in the gym. Birds can practice at home, lie flat with dumbbells in their hands, and then close their arms separately, just keeping their arms from bending, mainly because they don't bend to varying degrees during the process.
