The players of the National Football League are modern gladiators.

Each player needs to be in peak condition year-round to fend off incoming rookies and upstart backups—and battle the beastly maulers staring them down from across the line of scrimmage.

Football players get bigger, stronger, and faster every season, which means the best of the best have to work even harder to stay on top.

These players all know what it means to spend a ton of time in the gym.
