Someone who is exercising for self-esteem needs and self-care (more than anything else) would be able to say that exercise does not feel like work or a hardship because it is pleasurable. They would also be able to say they are flexible with themselves about when they go and what they do. This is because they know that they want to feel pleasure and enjoyment and not punishment or pressure.
Someone who exercises from a place of positive self-regard does only as much as is reasonable for their current state of health and trusts that, as their health and endurance improves, they will naturally choose to do more because they want to feel as strong and healthy as they can in their body. There is no need to pressure, cajole, threaten or berate themselves before, during or after exercising to ensure they “keep it up”. This is all old Drill Sgt. stuff. This is all coming from the belief that you cannot be trusted to do what is best for you, so you must be beaten into submission – for your own good, of course!
