I did 200-300 liters of squats every day for the first two days. Then leg press, brace, can practice "ma bu". In short, try to keep your muscles tense. If you feel there is still spare capacity, you can also tie sandbags to practice sprinting. On the last day, you can relax your legs and practice sprinting a little (don't tie sandbags)
In this way, the sports meeting can restore its previous state as much as possible.
