How often should I exercise to prevent getting sore?

[BumbleDeev]

So I've been excercising and running on the track at school, and i found my legs are gettng kind of sore. I have a dance competition next month so i need to practice dance a lot too.
I dont want to get too sore before the competition.
So what should my schedule be? how often should i exercise, run, and dance? and when should i take breaks?

What matters the most is the length of the exercise, for example, if you are a beginner try to gradually build up your exercise gradually so you don't get sore. And as you are a dancer try to balance your both timings. If you are dancing more than the usual try to lessen the running. After the exercise try walking, and always warm up before exercising. Stay hydrated as the lactic acid which causes soreness is soluble and less likely to be sore.

Once your legs are sore, just give them a full day of rest or until they are not sore anymore and continue your training. They will build endurance and strength to continually take the beating.
