Set the timer for 3 minutes.
Players have 1 minute to run from the baseline to the opposite baseline and back, 3 times.
****It is recommended to run 3 down & backs within 40 seconds, and have 20 seconds to rest.****
After 1 minute is over, they run from the baseline to the opposite baseline and back 3 times, again.
****Again, aim for 40 seconds running, 20 seconds rest.****
After the minute is over, the last round is up. They have 1 minute to run 3 down & backs.
This drill sounds easy, but it is NOT. It requires mental toughness, and stamina. This will wear your players out. Perfect drill for conditioning.
If the players cannot complete the drill within the time period, make the players run it again. Remind them that how much it hurts now, will be nothing compared to how much it will hurt if they have to do it again.
