Homemade barbell for sports

The main thing in sports is the desire to train! I made this bar myself. Scrap metal (this is a construction tool) and two bags filled with water bottles. The bags break from time to time. But one bag is enough for a month and a half of daily training. Everything is free. I didn't spend a dime on it. How much does the barbell they sell in stores cost? This is hundreds or even thousands of dollars.
