Unless you have legitimate health issues that make exercise painful, the anticipated cost is a greater than the actual cost.

It is still unrealistic to say that they are “very very high” though. The main barriers imo are not the perceived cost of exercise but the lack of perceived benefits. Certainly a health scare can make exercise seem more appealing.

The benefits of exercise are only seen over time. In the short term, the benefits may not outweigh the efforts so those seeking instant gratification will find it difficult to justify expending the effort. I don’t think it’s the costs being “very very high” that prevent most people from exercising.
