Much much better than doing shadowboxing with hand weights. As i have said before due to gravity the weight in the hand wants to go down so it wont help you with power and may even hinder your form.

A good solid resistsnce band anchored to a lowish to mid point means you use your whole body to punch through. They will increase handspeed and help with power due to the fact you are pushing out against reistance rather than your muscles fighting to keep your arm horizontal (like they are with handweights).

Shadowboxing with handweights IMO is useless and can sometimes cause shoulder probs.
