So, I went to Zumba last night. I wore heavy sweat pants which is not advisable in 90+ degree heat. I felt like i didn't work hard enough the week before because I didn't feel the pain afterward. I set out this week to really work it. I sweat hard and I took the squats as deep as I could stand and the lunges as high as I could. I worked hard and about 2/3 through the class I started to feel sick and dizzy and it was everything I could do to make it to the end. I don't advise that approach to exercise at all. I felt awful all night long. Today however I don't really ache but I feel stronger. I think I'm gonna start doing it twice a week. :) I will pace myself though. No more overdoing it.
