High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. [1] HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts.
Interval training is a type of training exercise that involves a series of high-intensity workouts interspersed with rest or break periods. The high-intensity periods are typically at or close to anaerobic exercise, while the recovery periods involve activity of lower intensity. [1]

As strength improves with high-intensity training (HIT), the weight or resistance used in the exercises should be gradually increased over time. This progressive overload is believed to provide the muscles with enough stimulus to continue improving and growing. An inverse relationship exists between how intensely and how long one can exercise.
Football strength is a training regime, considered the most complex physical quality to be developed by an athlete. [1] The training regime, exercises used, how the exercises are performed, and the types of equipment all play important roles in achieving desired results.
At free-kicks from short range, particularly when defending a direct free-kick, a wall of defensive players is lined up. The number of players who form the wall depends on the angle and distance from the goal, the opponent's assumed shooting skills, and the need to mark opponents to whom the ball might be passed.
Safeties are designated as strong safeties ("SS") or free safeties ("FS"). The strong safety usually plays closer to the line, matches up against tight ends, and is more involved in stopping the run. The free safety, on the other hand, typically plays farther from the line and acts as the "last line of defense" in both the pass and run game. [5]
