I always liked football because I see it as an extended session of interval training.I've always been told that swimming was good for building up your lung capacity and endurance. As a kid with asthma, swimming was recommended.
Why do you feel that football is the best?
Similar arguments for dirt biking and downhill biking for people who dont have the money and land to own a horse.I barrel race and trail ride with my horse. A lot of people think riding a horse you just sit there but that's not the case at all. You are working your core, legs and arms the whole time. If you are wanting to do something different besides the typical(nothing wrong with those) sports take some riding lessons. It's great for the soul and great for your body.
