The dynamic warm up and injury prevention exercises only require 70% effort. That passing exercise before possession doesn’t require your full focus and attention. Just run kinda hard and speed up the time between your touches a little bit more when your coach asks for game speed. No. No. And no. A good coach should know when to tailor training for more relaxed efforts and will tell you. Otherwise, players should be switched on, especially at the start of a training session. Unless you are learning a brand-new skill where slowing down is important, training should involve speeds and pressures similar to what we encounter in a match. Even that passing exercise you’ve done 10 million times.
