I have started doing them with sprints, pushups and ab work and defently noticed a difference within 3 weeks. Maybe give them a go on your heavy bag flat out punching for 20 seconds 10 second break and repeat. But watch out it is quite intense.
that post is the tabata intervals, can apply it to anything. more about the specifics on the earlier post.
