It doesn't cost much money for our youth to start exercising every day. They don't even need to be on a sports team or club. Concentration should be on exercises that encourage core strength, balance, flexibilty and muscle endurance. Many of these exercises require little else but their body weight and their effort. Examples are circuit jump roping, squats, lunges, single-leg squats, single-leg squat touchdowns, pushups, pullups, bridges, supergirls and ladder drill exercises.
