Is going to two fitness classes in one day over kill?
I have bootcamp tomorrow evening but think I might squeeze in a class in the morning. Don't want to overdo it though. I have been exercising 8 weeks now and have built up to at least an hour 6 days a week, mostly interval type stuff.
The problem is my knees are pretty sore and I don't want to cause an injury. Ate sore knees normal?
