Training Woes

Today I'm really struggling with my training program. I just don't want to do it! I'm focusing on building strength in my knees and ankles so that I don't have as much pain when I walk longer distances, but I'm just not motivated. I don't know what the answer is other than Just Do It! I'll try to force myself today and maybe ask some people at the gym how they stay motivated. I'll also listen to podcasts for answers while I work. Maybe that will help...I hope so!
