Possible tax credits for exercise equipment. My husband’s employer funded e-bikes for us this year up to $1,000 per person. We have over 300 miles on these bikes that we purchased in May. Which is quite a lot considering we both work full-time. I believe that a reward system would help motivate some people to get/stay in shape. Some people will of course cheat and sell the stuff, but I believe it could make a difference for some of the population.
Another idea would be tax benefits for people staying within a healthy weight category. I don’t agree with punishing people for being overweight but motivating people to stay in a healthy weight maybe effective.
