Rusty was one of the first fitness bloggers I followed online. With his speciality being in helping men and women add muscle definition while staying slim enough to fit into stylish clothing. His unique "definition without excess size" approach to fitness is perfect for anyone who wants that lean and muscular GQ look. 

Chris Lopez is one of the world’s top kettlebell experts. He lives in a remote surfing village on the Caribbean side of Costa Rica and his only piece of workout equipment is the kettlebell. He’s been training with kettlebells since 2003 and has received his Russian Kettlebell certification directly from Pavel Tsatsouline (world renowned trainer to special forces soldiers and featured on Joe Rogan). In other words, Chris is as legit as they come when it comes to kettlebell training.
