American Football can be described as a chess match with shoulder pads, with the strategic element just as important as the physical skills of those playing.
It is a game for all shapes and sizes, with 20-stone blockers featuring in the same team as speedy pass catchers. For those who are not comfortable with the contact element, flag football features many of the same skills without the hard tackling.

Why is it good for you?
American football is a sport where you can improve skills of all types, from physical technique and endurance to communication and analytical skills.
The fact that there are separate offensive and defensive teams mean that while endurance plays a part, often explosive physical skills and good technique, as well as being switched on mentally, are more important to a player's success.
Designed plays test memory skills, analytical skills when determining what the other team might do based on their formation, while also being able to communicate roles to team-mates is pivotal.
Balance, leverage and body control are big parts of the sport, where correct application of skills such as blocking and tackling will beat raw physical ability every time.
The amount of calories you can burn depends on your weight, position and the amount of time you are in the game, but can be up to 500 calories an hour for lighter players and 900 calories an hour for heavier players.

American football evolved slowly from a combination of football and rugby, with a number of universities changing the rules of each to create new types of sport.
In the 1880s, a man named Walter Camp introduced standardised rule changes into this new hybrid sport, which resulted in the first evolution of the sport we know today.
The National Football League was formed in 1920 and was the principal league until the 1960s, when the rival American Football League became a legitimate competitor.
In 1966, the two leagues agreed to play a season-ending fixture to decide the best team in both competitions. This was the start of the Super Bowl. The leagues fully merged in 1970, creating the two "conference" NFL that is still in existence today.
