I would be more motivated by participating in physical activities that are recreational. Competitive activities may be a big responsibility because you have to aim for a win. If you will be exercising regularly, it will make you happy without any aim of winning in a contest. Just like playing sports such as badminton, basketball, volleyball, baseball, and soccer which need a team. These recreational activities will be advisable because you are with others who love the sport also but not treating it as a competition.
