What does hiting a heavy bag do like what does it do?

Question

Does it build power, speed or what

Answer 1

Mainly power and stamina. A pretty good all round bet for training as it helps with most of the skills needed such as endurance, co-ordination etc

Answer 2

nice double question. just a suggestion you should think before you type out your questions. the heavy bag can be used to build speed if you use it in that manner but mainly the heavy bag is important for build endurance and power.
