Working out

So - I am trying hard to get back in the routine of going to the gym everyday at lunch time. What do I do today...forget my clothes at home. NICE. How can I work out with out my gym clothes? I'm considering running to the store to buy new ones - but I really don't have enough money to go buy a whole new set of clothes. Oh well - I will take the kids for a bike ride tonight - that will work. I want to lose 5 lbs before we head up to Ohio this weekend. I'm watching my food and getting exercise everyday - I certainly think I can drop that. Mostly just water anyway! I'll let you know...I did already drop 1.5 lbs from yesterday, that's a great start!
