Re: Soreness and aerobic execise
Soreness indicates that you have been exercising close to your limit and your muscles need to heal and grow in response. You may want to do hard workouts every other day to give your muscles time to heal and grow between workouts. After some period of time, the same workouts will no longer be as hard, and you should not feel much soreness after them, due to your muscles growing in response to the exercise. You may then be able to do them every day if you wish.
