I hate exercising anyway but every now and then I get in a groove where I could keep going for hours. I was in that groove today when I went to the gym during my lunch and after 40 mins I had to stop. I really wanted to keep going but I had to have time to shower before returning to work.
I always judge my workout success by how wet my shirt is. Today you could clearly see the dry outline of my sports bra. Hope I'm in the groove again tomorrow.
