Shadow Boxing is a great way to warm up or work on the form. At times, the boxers will eventually get bored of shade and there is nothing wrong with that. Sometimes we have to do something differently in order to stay motivated with our boxing training. One thing common to see boxers mix your routine is the shadow boxing with hand weights.
You can buy weighted gloves but I use weights and work very well for me. In order to effectively shadow box with weights, I recommend using very light weights. When people start shadow boxing with weights, often they will use heavy weights, thinking that will benefit from a difficult exercise. This is simply not true. I do not suggest shadow boxing with weights greater than 5 lbs.

When you start shadow boxing with weights, the main objective is to maintain the speed of their struggle against nature. Your strokes should remain fast. If you can not pull your punches without falling his arm, you need to use lighter weights. at 140-145 pounds, I use 3 pesos per pound. If you are a medium or heavy weight, I suppose it is reasonable to use 5 pesos per pound, while the shading.
It is important to be safe with any form of boxing training. Be very careful about adding weight to your boxing routine. You can easily damage your elbow joint hyper-extension. You want very little stress on your joints as possible. Elbow injuries are very difficult to recover. If in doubt, use light weights.
