I'm really excited about this post, because, well, it wasn't me who wrote it. I have invited my first ever guest blogger, Natalie, to write about summer exercise. A survivor of a half iron man, countless marathons, half marathons, triathlons, team relays, and numerous other outdoor competitions, Natalie takes the cake when it comes to training and exercising. Therefore, read this blog carefully. She also has her own blog, which is full of humor, tips, tricks, and giveaways.
