Anybody know some good boxing exercises

Running and punching the heavy bag have put boxers in fighting shape for a few hundred years if they eat nutritious food and keep their weight down. There are many other exercises you could do but those two basics will get you in at least 95 percent shape if you do them consistently. Shadow boxing is also a good simple exercise you can do alone. Pushups, chinups, dips, leg presses and weights can build strength but many great old champions never lifted weights. Swimming is also good.
