Exercise is suppose to be enjoyed not hated. Sure as humans we are going to have days where we don't feel like working out or eating healthy. That will always come up. How we view it and what we do with it is another story. It's summer. Try new things. Ever done stand up paddling, gone hiking, horse back riding, rollar skating, canoeing, etc...? You never know sitting there thinking about it.
GO do it! Enjoy the summer and stay healthy!
