For this fun and interactive soccer warm up you let the players make a circle around you, about 15 meters away from you. So you are standing in the middle of the circle.
IMPLEMENTATION:
The starting point of the players is their place in the circle, they stay "jogging" in place.
Call: "Inside" and all players sprint towards you up to a meter or two away. Then they turn around and quickly sprint back to their spot where they keep moving.
Call: "Outside" and all players sprint away from you until you call "Back", then everyone returns to the starting position in the circle.
QUALITY:
Make sure players do not stand on their flat feet, but always on their toes.
Players should sweat heavily after this exercise.
PREVENTION:
You can apply different variations: sit-ups, push-ups, jump up, knees up by base position, sprint to the right or left while maintaining the circle shape.
