Punishment isn't very effective on its own and love bombing is great for helping repair or improve a relationship, but isn't that good for improving specific behaviours in a targeted way.
With punishment what they say is that only something very token/basic is necessary because punishment only works as a component in a larger system anyway. The overall system should be more positive, targeted and specific in order to be effective.
If you are finding that punishment isn't working and/or you're constantly having to increase it to something stronger then you have one of two problems:
- Your overall system isn't structured enough
- Your child can't meet your expectation
It makes sense to start with the system because this works for the majority of children. This is a good one:

The course is free and you can just do a small part and then stop and practice the tools before you continue. Each tool is usable on its own and you can start with the first one immediately and get helpful effects, but they do work best when combined together.
They both sound high energy/sensory seeking which can be a component of ADHD (or might not be anything diagnosable at all). It's worth getting on an ADHD waiting list especially for your DS I would say. It doesn't hurt anything and if you don't need the appointment any more by the time it comes around you could always cancel it. Thinking about them as needing exercise/walks like dogs is a very good way to think about it as it does really help with children with high energy. You can look more into this later (sensory seeking is a good search term) but starting just with daily physical activity will probably help immediately.
What commonly happens when you have children with this kind of profile is that you will ask them to do something, they will refuse/be rude back and you'll get annoyed or angry and ask them in a firmer tone, they will then increase the rudeness and you get angry and threaten something and then they get angrier which means you end up threatening more, it's like a spiral. Then the general outcome of this is that either you end up snapping and doing something you regret (giving a harsh punishment, screaming/bellowing, maybe being physical with them e.g. hitting or pushing or dragging) OR in order to avoid this you leave the situation and they have successfully avoided whatever it was you asked them to do. Once you have got into this pattern, it won't usually go away on its own - you have to totally change your approach. If this is a common pattern in your household, and it's quite taboo to admit that it is, the above course is a targeted intervention that works very well to address that. (It's also generally a helpful parenting course even if this isn't happening).
Troubleshooting
If you go through the course and implement the steps and it's still not helpful then you have probably moved into "child can't meet expectations". There is some exploration of "can't meet" in the course in the shaping technique (where you break down a wanted behaviour into achievable steps) - this is a good thing to try first, but you might want to also think about other steps such as looking at some kind of assessment.
Another good option to try for "can't meet expectations" is Ross Greene's Explosive Child technique - this is a problem solving approach which rather than trying to motivate the child to behave differently enables you to discuss with them how to meet the expectation in a way that meets both your and their needs (A good introductory talk on youtube if you search "Ross Greene ODD ADHD")
If you find that it's hard to keep yourself calm enough to do the steps of the parenting course, there is a great book called When Your Kids Push Your Buttons which helps both with emotional regulation strategies for yourself and some of the seeing-both-sides approach which can help communication between you and the DC. If you are struggling in general you may also want to ask your GP for mood support (antidepressants, counselling, possibly look into perimenopause, ADHD etc) or whether they can refer to any in-person parenting support, because in person can help more than online.
If exercise seems to help a bit, but not enough, then look into more sensory support. "Sensory seeking" is a great search term though this is a bit of a wild west of confusing/conflicting info. Sensory needs are mainly associated with autism although there is more recent thinking that they can apply in a less extreme way to ADHD and to some people without any kind of diagnosis.
If even positive reinforcement seems to be making things worse, look into demand avoidance - again the Ross Greene techniques can be good for children who struggle with demand avoidance. (I don't know a lot more about it than this).
If their more defiant/aggressive behaviour is strongly linked with the hyperactivity and it doesn't respond in any way to any kind of motivation (positive or negative) or if you have a sense they aren't really "in control" when they are doing this, look up "stress behaviour" or "dysregulation behaviour". The three brain model (cognitive/emotional/survival) can be useful here (found in Conscious Parenting, Dan Siegel's books, and Self-Reg by Stuart Shanker).
