What it's like to train like an NFL player

American Football seems intense. It's a game filled with powerful collisions and strategic touchdowns. But what happens off the field? How do NFL players maintain such great strength and endurance?

There's no doubt it's an All-American sport, but it has a "rapidly growing following in the UK," says Bath-born Alex Jenkins, a New Orleans Saints player.

With one more game to be held at the Twickenham Stadium this Sunday October 29, we caught up with Jenkins to see what it's like to switch from playing soccer in England to American football in the US.

He said that over the years his training for the draft has elevated and has got harder to keep up with the competition. "Just drilling hard, doing the same things every day, learning the technique, getting stronger, faster and leaner," he said.

He said it took him about two months to change his body from being a soccer player to being an American football player. He had to become more powerful and more explosive in a short amount of time. "With soccer you have long intervals of medium-intensity running," he explained. "But with football, it's more short intervals of high-intensity power output."
